Abstract
Group A rotavirus is the leading cause of acute gastroenteritis in cattle and swine. Although, vaccination against this virus is an effective strategy for prevention, additional strategy to control disease is necessary. Egg yolk immunoglobulin (IgY)-based passive immunization could be a better option in preventing this disease. Bovine rotavirus (BRV) is group A rotavirus and possesses a genome of 11 segments of double-stranded RNA. The outer layer of capsid is composed of two proteins (VP7 and VP4), which induce virus neutralizing antibodies. Trypsin cleavage of VP4 produces VP8 (28 kDa) and VP5 (60 kDa) fragments. Since a number of studies have demonstrated the induction of neutralizing antibodies using VP8 subunit vaccines, we have produced IgY against the recombinant VP8. The cDNA spanning the VP8 subunit was amplified from bovine rotavirus-infected cells and cloned into pET21d(+) expression vector to generate recombinant VP8. The resulting carboxy-terminal His-tagged VP8 proteins were expressed in Escherichia coli strain BL21(DE3) by isopropyl β-D-1-thiogalactopyranoside (IPTG) induction. The recombinant proteins were purified using Ni-NTA agarose beads, and the purified protein was used as the immunizing agent to produce polyclonal antibodies in chicken. The resulting polyclonal antisera specifically recognized VP8 in Western blot assay and were able to neutralize BRV replication in cell cultures. These results demonstrate that IgY can be used in immunological assays and, in addition, in passive immunization of newborn calves against BRV.

Abstract
A Gram-stain-negative, non-flagellated, non-gliding, aerobic and rod-shaped or ovoid bacterium, designated strain KEM-10T, was isolated from water in an estuary environment in the Yellow Sea, South Korea, and subjected to a polyphasic taxonomic study. Strain KEM-10T grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of 2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain KEM-10T belonged to the genus Algoriphagus, joining the type strain of Algoriphagus litorisediminis showing 97.4 % sequence similarity. Strain KEM-10T exhibited 16S rRNA gene sequence similarity of 92.2-96.1 % to the type strains of the other Algoriphagus species. Strain KEM-10T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the major fatty acids. The major polar lipids detected in strain KEM-10T were phosphatidylethanolamine and phosphatidylcholine. The DNA G+C content of strain KEM-10T was 40.6 mol%. The mean DNA-DNA relatedness value between strain KEM-10T and the type strain of A. litorisediminis was 12 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain KEM-10T is separated from recognized species of the genus Algoriphagus. On the basis of the data presented, strain KEM-10T is considered to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus aquaemixtae sp. nov. is proposed. The type strain is KEM-10T (=KCTC 52839T=NBRC 112780T).

Abstract
A Gram-stain-negative, coccoid to oval-shaped and non-motile bacterial strain, designated MM-7T, was isolated from seawater of the Yellow Sea, South Korea, and was subjected to a polyphasic taxonomic study. Strain MM-7T grew optimally at pH 7.0-8.0, at 25 °C and in the presence of 2-3 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain MM-7T joins the branch comprising the species of the genus Roseobacter, clustering with the type strains of Roseobacter litoralis and Roseobacter denitrificans, with which it exhibited 97.9 and 96.8 % sequence similarity values, respectively. The DNA G+C content of strain MM-7T was determined to be 60.8 mol%, and its mean DNA-DNA relatedness values with Rsb. litoralis JCM 21268T was 10.3±0.4 %. Strain MM-7T contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) as the major fatty acid. The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain MM-7T is distinguishable from other species of the genus Roseobacter. On the basis of the data presented, strain MM-7T is considered to represent a novel species of the genus Roseobacter, for which the name Roseobacter ponti sp. nov. is proposed. The type strain is MM-7T (=KCTC 52469T=NBRC 112431T).

Abstract
A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterium, designated OITF-20T, was isolated from the tidal flat in Oido, an island of South Korea. The novel strain grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain OITF-20T fell within the clade comprising the type strains of species of the genus Lutibacter. Strain OITF-20T exhibited 16S rRNA gene sequence similarity values of 97.8, 97.6 and 97.6 % to the type strains of Lutibactercrassostreae, Lutibacterflavus and Lutibacterlitoralis, respectively, of 94.9-96.8 % to the type strains of the other species of the genus Lutibacter and of less than 93.4 % to the type strains of the other recognized species. Strain OITF-20T contained MK-6 as the predominant menaquinone and iso-C15 : 0 3-OH, C15 : 1ω6c and iso-C15 : 0 as the major fatty acids. The major polar lipids of strain OITF-20T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain OITF-20T was 31.1 mol% and its mean DNA-DNA relatedness values with the type strains of L. crassostreae, L. flavus and L. litoralis were 17-27 %. The differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain OITF-20T is separated from other recognized species of the genus Lutibacter. On the basis of the data presented, strain OITF-20T is considered to represent a novel species of the genus Lutibacter, for which the name Lutibacter litorisediminis sp. nov. is proposed. The type strain is OITF-20T (=KCTC 52501T=NBRC 112458T).

Abstract
A Gram-stain-negative, facultative aerobic, non-flagellated, and rod-shaped bacterium, designated AR-13(T), was isolated from a seawater on the East Sea in South Korea, and subjected to a polyphasic taxonomic study. Strain AR-13(T) grew optimally at 30°C, at pH 7.0-8.0 and in the presence of 0-0.5% (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences showed that strain AR-13(T) fell within the clade comprising the type strains of Arcobacter species, clustering coherently with the type strain of Arcobacter venerupis. Strain AR-13(T) exhibited 16S rRNA gene sequence similarity values of 98.1% to the type strain of A. venerupis and of 93.2-96.9% to the type strains of the other Arcobacter species. Strain AR-13(T) contained MK-6 as the only menaquinone and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), C16:0, C18:1 ω7c, and summed feature 2 (iso-C16:1 I and/or C14:0 3-OH) as the major fatty acids. The major polar lipids detected in strain AR-13(T) were phosphatidylethanolamine, phosphatidylglycerol, and one unidentified aminophospholipid. The DNA G+C content was 28.3 mol% and its mean DNA-DNA relatedness value with the type strain of A. venerupis was 21%. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain AR-13(T) is separated from recognized Arcobacter species. On the basis of the data presented, strain AR-13(T) is considered to represent a novel species of the genus Arcobacter, for which the name Arcobacter acticola sp. nov. is proposed. The type strain is AR-13(T) (=KCTC 52212(T) =NBRC 112272(T)).

Abstract
A Gram-stain-negative, non-spore-forming, non-flagellated and coccoid, ovoid or rod-shaped bacterial strain, HDSW-34T, was isolated from seawater of Hwang-do on the Yellow Sea, South Korea, and subjected to a taxonomic study using a polyphasic approach. Strain HDSW-34T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain HDSW-34Tclustered with the type strains of four species of the genus Octadecabacter, showing 96.7-97.6 % sequence similarity. Strain HDSW-34T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids detected in strain HDSW-34T were phosphatidylcholine, phosphatidylglycerol, one unidentified aminolipid and one unidentified lipid.

Abstract
A Gram-stain-positive, facultatively anaerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, GHD-1T, was isolated from a tidal flat sediment on the Yellow Sea, South Korea. It grew optimally at 30 °C, at pH 6.5-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain GHD-1T fell within the cluster comprising the type strains of species of the genus Demequina. Strain GHD-1T exhibited 16S rRNA gene sequence similarity values of 97.0-98.8 % to the type strains of Demequinaglobuliformis, D. salsinemoris, D. flava, D. sediminicola and D. activiva, and of 95.5-96.9 % to the type strains of the other species of the genus Demequina. The peptidoglycan type of strain GHD-1T is A4β based on l-Orn-l-Ser-l-Asp. It contained DMK-9(H4) and DMK-8(H4) as the major menaquinones and anteiso-C15 : 0, C16 : 0, iso-C16 : 0 and anteiso-C17 : 0 as the major fatty acids. The major polar lipids were phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and one unidentified glycolipid. The DNA G+C content of strain GHD-1T was 68.7 mol%, and its DNA-DNA relatedness values with the type strains of five phylogenetically related species of the genus Demequina were 13-29 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain GHD-1T is separated from other recognized species of the genus Demequina. On the basis of the data presented, strain GHD-1T is considered to represent a novel species of the genus Demequina, for which the name Demequina litorisediminis sp. nov. is proposed. The type strain is GHD-1T (=KCTC 52260T=NBRC 112299T).

Abstract
A Gram-stain-negative, aerobic, non-flagellated and pleomorphic bacterium, designated HJR-2T, was isolated from a junction between the ocean and a freshwater lake on the East Sea, South Korea. It grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 0-1.5 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain HJR-2T clustered with the type strains of Vasilyevaea enhydra and Vasilyevaea mishustinii and this cluster fell within the clade comprising the type strains of Devosia species. Strain HJR-2T exhibited 16S rRNA gene sequence similarity values of 97.2 and 97.0 % to the type strains of V. enhydra and V. mishustinii, respectively, and 93.9-96.2 % to the type strains of Devosia species. Strain HJR-2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c, 11-methyl C18 : 1ω7c and C16 : 0 as major fatty acids. Major polar lipids of strain HJR-2T were phosphatidylglycerol and two unidentified glycolipids. The DNA G+C content was 66.0 mol% and its mean DNA-DNA relatedness values with the type strains of V. enhydra and V. mishustinii were 11-17 %. Differential phenotypic properties, together with its phylo genetic and genetic distinctiveness, revealed that strain HJR-2T is separated from V. enhydra, V. mishustinii and Devosia species. On the basis of the data presented, strain HJR-2T (=KCTC 52211T=NBRC 112271T) is considered to be the type strain of a novel species of the genus Devosia, for which the name Devosiaconfluentis sp. nov. is proposed. In this study, it is also proposed that V. enhydra and V. mishustinii be reclassified as members of the genus Devosia.

Abstract
A Gram-stain-negative, aerobic, motile and rod-shaped or ovoid bacterial strain, designated YSM-23T, was isolated from a tidal flat on the South Sea in South Korea, and subjected to a polyphasic taxonomic study. Strain YSM-23T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences showed that strain YSM-23T represented a member of the genus Colwellia. Strain YSM-23T exhibited 16S rRNA gene sequence similarity values of 98.0, 97.4 and 97.3 % to the type strains of Colwellia aestuarii, Colwellia polaris and Colwellia chukchiensis, respectively, and of 94.5-96.8 % to the type strains of the other species of the genus Colwellia. Strain YSM-23T contained Q-8 as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the major fatty acid. The major polar lipids detected in strain YSM-23T were phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content of strain YSM-23T was 43.8±0.08 mol% and its DNA-DNA relatedness values with the type strain of C. aestuarii, C. polaris and C. chukchiensis were 10±3.5-22±4.9 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain YSM-23T is separated from species of the genus Colwelliawith validly published names. On the basis of the data presented, strain YSM-23T is considered to represent a novel species of the genus Colwellia, for which the name Colwellia sediminilitoris sp. nov. is proposed. The type strain is YSM-23T (=KCTC 52213T=NBRC 111994T).

Abstract
A Gram-stain-negative, aerobic, non-spore-forming, motile by gliding and coccoid, ovoid or rod-shaped bacterial strain, designated GHTF-27T, was isolated from a tidal flat at Goheung, South Korea, and subjected to a taxonomic study using a polyphasic approach. The novel strain grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2.0-5.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain GHTF-27T belongs to the genus Gramella. It exhibited 16S rRNA gene sequence similarity values of 97.6-98.3 % to the type strains of Gramella aestuariivivens, Gramella echinicola, Gramella gaetbulicola, Gramella aquimixticola, Gramella aestuarii and Gramella portivictoriae, respectively, and of 93.8-96.7 % to the type strains of the other species of the genus Gramellawith validly published names. Strain GHTF-27T contained MK-6 as the predominant menaquinone and iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids of strain GHTF-27T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain GHTF-27T was 39.7 mol% and DNA-DNA relatedness values with the type strains of the six phylogenetically closely related species of the genus Gramellawere 12-28 %. The differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain GHTF-27T is separated from other species of the genus Gramella. On the basis of the data presented, strain GHTF-27T is considered to represent a novel species of the genus Gramella, for which the name Gramella sediminilitorissp. nov. is proposed. The type strain is GHTF-27T (=KCTC 52208T =NBRC 111992T).

Abstract
A Gram-stain-negative, non-flagellated, non-gliding and rod-shaped bacterial strain, designated GM-5T, was isolated from seawater from near the Korean peninsula. Strain GM-5T was found to grow optimally at pH 7.0-8.0, at 25 °C and in the presence of 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain GM-5T falls within the clade comprising the genus Roseivirga, with which it exhibits 94.8-96.8 % sequence similarity. Strain GM-5T was found to contain MK-7 as the predominant menaquinone and iso-C15 : 1 G, iso-C15 : 0, and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids were identified as phosphatidylethanolamine, an unidentified phospholipid and two unidentified lipids. The DNA G+C content of strain GM-5T was determined to be 42.3 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, revealed that strain GM-5T is distinguishable from species of the genus Roseivirga with validly published names. On the basis of the data presented, strain GM-5T is proposed to represent a novel species of the genus Roseivirga, for which the name Roseivirga maritima sp. nov. is proposed. The type strain is GM-5T (=KCTC 42718T =NBRC 111589T).

Abstract
A new secondary metabolite, named griseusrazin A (1), was isolated from the marine-derived bacterium Streptomyces griseus subsp. griseus. The structure of the compound was determined by analysis of spectroscopic data including MS, COSY, HSQC, HMBC, and (15)N-HMBC data. Griseusrazin A (1) inhibited the production of inflammatory mediators, such as prostaglandin E2 and nitric oxide, which was mediated through the suppression of the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. The production of pro-inflammatory cytokines, such as interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α, in the LPS-stimulated cells was also effectively blocked by griseusrazin A (1). Furthermore, this anti-inflammatory activity of 1 was linked to its inhibitory effects against the nuclear translocation of NF-κB p50 and p65, as wells as NF-κB binding activity. In the further study to elucidate the anti-inflammatory mechanism, 1 was shown to induce heme oxygenase-1 (HO-1) expression through the enhancement of nuclear translocation of nuclear factor E2-related factor 2. Furthermore, the anti-inflammatory activity of 1 in the LPS-stimulated cells was partially reversed by an HO inhibitor, tin protoporphyrin. These results indicate that the anti-inflammatory effect of 1 is associated with Nrf2-mediated HO-1 expression.

Abstract
A Gram-stain-negative, coccoid- or short-rod-shaped and non-motile bacterial strain, designated MDM-7T, was isolated from seawater of the Yellow Sea, South Korea, and was subjected to a polyphasic taxonomic study. Strain MDM-7T grew optimally at pH 7.0-8.0, at 30 °C and in the presence of 2-3 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain MDM-7T fell within the clade comprising species of the genus Loktanella, clustering with the type strains of Loktanella vestfoldensisand Loktanella agnita, with which it exhibited 96.1 and 95.6 % similarity, respectively. 16S rRNA gene sequence similarity values between strain MDM-7T and the type strains of other Loktanella species were 93.1-95.0 %. The DNA G+C content of strain MDM-7T was 62.6 mol%. Strain MDM-7T contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/ or C18 : 1ω6c) as the major fatty acid. The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol and an unidentified aminolipid. Differential phenotypic properties, together with phylogenetic distinctiveness, demonstrated that strain MDM-7T is distinguishable from recognized Loktanella species. On the basis of the data presented, strain MDM-7T is considered to represent a novel species of the genus Loktanella, for which the name Loktanella marina sp. nov. is proposed. The type strain is MDM-7T (=KCTC 42722T=CECT 8899T).

Abstract
A Gram-stain-negative, aerobic, motile, rod-shaped or ovoid bacterial strain, designated DB-2T, was isolated from a tidal flat of the Yellow Sea in South Korea, and subjected to a taxonomic study using a polyphasic approach. Strain DB-2T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2.0-3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain DB-2T belonged to the genus Pseudoalteromonas. Strain DB-2T exhibited 16S rRNA gene sequence similarities of 97.17-97.36 % to the type strains of Pseudoalteromonas mariniglutinosa, Pseudoalteromonas spongiae and Pseudoalteromonas tetraodonis and of 93.79-96.99 % to the type strains of the other species of the genus Pseudoalteromonas. Strain DB-2T contained Q-8 as the predominant ubiquinone and C16 : 0, C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C12 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain DB-2T were phosphatidylglycerol, phosphatidylethanolamine, two unidentified glycolipids, an unidentified phospholipid and an unidentified aminolipid. The DNA G+C content of strain DB-2T was 54.9 ± 0.2 mol% and mean DNA-DNA relatedness values with the type strains of P. mariniglutinosa, P. spongiae and P. tetraodonis were 10-17 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain DB-2T is separated from recognized species of the genus Pseudoalteromonas. On the basis of these data, strain DB-2T is considered to represent a novel species of the genus Pseudoalteromonas, for which the name Pseudoalteromonas aestuariivivens sp. nov. is proposed. The type strain is DB-2T ( = KCTC 42779T = CECT 8945T).

Abstract
A Gram-stain-negative, motile, aerobic, rod- or ovoid-shaped bacterium, designated DB-1T, was isolated from a tidal flat on the Yellow Sea in South Korea and subjected to a taxonomic study using a polyphasic approach. Strain DB-1T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 0.5-2.0% (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain DB-1T falls within the clade comprising species of the genus Marinobacterium, clustering coherently with the type strain of Marinobacterium nitratireducens and showing a sequence similarity value of 98.4 %. The novel strain exhibited 16S rRNA gene sequence similarities of 91.5-94.4 % to the type strains of other species of the genus Marinobacterium. Strain DB-1T contained Q-8 as the predominant ubiquinone and C18:1ω7c, summed feature 3 (C16:1ω7c and/or C16:1ω6c) and C16:0 as the major fatty acids. The major polar lipids detected in strain DB-1T were phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminolipid, one unidentified glycolipid, one unidentified phospholipid and two unidentified lipids. The DNA G+C content of strain DB-1T was 62.3 mol% and the mean DNA-DNA relatedness value with the type strain of M. nitratireducens was 21±4.6%. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain DB-1T is separated from recognized species of the genus Marinobacterium. On the basis of the data presented, strain DB-1T is considered to represent a novel species of the genus Marinobacterium, for which the name Marinobacterium aestuariivivens sp. nov. is proposed. The type strain is DB-1T (=KCTC 42778T=NBRC 111756T).

Abstract
A Gram-stain-negative, motile, aerobic and rod-shaped bacterium, designated HJM-18T, was isolated from the place where the ocean and a freshwater lake meet at Hwajinpo, South Korea, and subjected to a taxonomic study using a polyphasic approach. Strain HJM-18T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 1.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain HJM-18T belonged to the genus Marinobacter. Strain HJM-18T exhibited 16S rRNA gene sequence similarity values of 97.05–98.22 % to the type strains of Marinobacter algicola, Marinobacter flavimaris, Marinobacter adhaerens, Marinobacter salarius, Marinobacter salsuginis, Marinobacter guineae and Marinobacter gudaonensis and of 93.21–96.98 % to the type strains of the other species of the genus Marinobacter. Strain HJM-18T contained Q-9 as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω9c as the major fatty acids. The major polar lipids detected in strain HJM-18T were phosphatidylethanolamine, phosphatidylglycerol and one unidentified aminophospholipid. The DNA G+C content was 58 mol% and the mean DNA–DNA relatedness values with the type strains of the seven phylogenetically related species of the genus Marinobacter were 10–27 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain HJM-18T is separated from recognized species of the genus Marinobacter. On the basis of the data presented, strain HJM-18T represents a novel species of the genus Marinobacter, for which the name Marinobacter confluentis sp. nov. is proposed. The type strain is HJM-18T ( = KCTC 42705T = NBRC 111223T).

Abstract
A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped bacterial strain, designated SSK3-2T, was isolated from the locality where the ocean and a freshwater spring meet at Jeju island, South Korea, and subjected to a polyphasic taxonomic study. Strain SSK3-2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain SSK3-2T clustered with the type strain of Primorskyibacter sedentarius, with which it exhibited 97.3 % sequence similarity. Strain SSK3-2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids detected in strain SSK3-2T were phosphatidylcholine, phosphatidylglycerol, one unidentified lipid and one unidentified aminolipid. The DNA G+C content of strain SSK3-2T was 60.6 mol% and its mean DNA–DNA relatedness value with P. sedentarius JCM 16874T was 19 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK3-2T is separated from P. sedentarius. On the basis of the data presented, strain SSK3-2T is considered to represent a novel species of the genus Primorskyibacter, for which the name Primorskyibacter insulae sp. nov. is proposed. The type strain is SSK3-2T ( = KCTC 42602T = CECT 8871T).

Abstract
A Gram-strain-negative, coccoid or oval-shaped, non-motile bacterial strain, designated MDM-1T, was isolated from a tidal-flat sediment on the Korean peninsula. Strain MDM-1T was found to grow optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain MDM-1T falls within the clade comprising species of the genus Algoriphagus, clustering with the type strains of Algoriphagus halophilus, A. lutimaris, A. chungangensis and A. machipongonensis, with which it exhibited 97.2–98.5 % 16S rRNA gene sequence similarity. Sequence similarities to the type strains of the other recognized species of the genus Algoriphagus were 92.8–97.6 %. Strain MDM-1T was found to contain MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) as the major fatty acids. The major polar lipids were identified as phosphatidylcholine, phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain MDM-1T was determined to be 42.7 mol% and the mean DNA–DNA relatedness with A. halophilus KCTC 12051T, A. lutimaris S1-3T, A. chungangensis KCTC 23759T, A. machipongonensis DSM 24695T and A. ratkowskyi CIP 107452T was 19.7–5.2 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain MDM-1T is distinguishable from recognized species of the genus Algoriphagus. On the basis of the data presented, strain MDM-1T is proposed to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus aestuarii sp. nov. is proposed. The type strain is MDM-1T ( = KCTC 42199T = NBRC 110552T).

Abstract
A Gram-stain-negative, aerobic, non-spore-forming bacterial strain, motile by gliding and with rod-shaped or ovoid cells, was isolated from water of an estuary environment at Hwajinpo, South Korea. The strain was designated HJM-19T and subjected to a polyphasic taxonomic study. The novel strain grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 1.0-2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain HJM-19T belongs to the genus Gramella. It exhibited 16S rRNA gene sequence similarity values of 97.2-98.1 % to the type strains of Gramella portivictoriae, Gramella aestuariivivens, Gramella marina, Gramella echinicola and Gramella aestuarii, and of 93.9-96.5 % to the type strains of the other species of the genus Gramella with validly published names. Strain HJM-19T contained MK-6 as the predominant menaquinone and anteiso-C15 : 0, anteiso-C17 : 1ω9c and C17 : 0 2-OH as the major fatty acids. The major polar lipids of strain HJM-19T were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain HJM-19T was 48.0 mol%, and its DNA-DNA relatedness values with the type strains of the five phylogenetically closely related species of the genus Gramella were 11-23 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain HJM-19T is separated from other species of the genus Gramella. On the basis of the data presented, strain HJM-19T is considered to represent a novel species of the genus Gramella, for which the name Gramella aquimixticola sp. nov. is proposed. The type strain is HJM-19T ( = KCTC 42706T = NBRC 111224T).

Abstract
A Gram-stain-negative, aerobic, non-motile and rod-shaped bacterial strain, designated W-WS13T, was isolated from wood falls collected around Wando, an island in the South Sea of South Korea, and subjected to a polyphasic taxonomic study. Strain W-WS13T grew optimally at 30 °C, at pH 7.5 and in the presence of 0.5 % NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain W-WS13T belonged to the genus Pedobacter, clustering robustly with the type strain of Pedobacter arcticus, sharing 95.9 % sequence similarity. Strain W-WS13T exhibited 16S rRNA gene sequence similarity of 90.1–95.6 % to the type strains of the other species of the genus Pedobacter. Strain W-WS13T contained MK-7 as the predominant menaquinone and iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipid detected in strain W-WS13T was phosphatidylethanolamine. The DNA G+C content of strain W-WS13T was 36.9 mol%. Phylogenetic distinctiveness and differential phenotypic properties of strain W-WS13T revealed that the novel strain is separated from recognized species of the genus Pedobacter. On the basis of the data presented, strain W-WS13T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter lignilitoris sp. nov. is proposed. The type strain is W-WS13T ( = KCTC 42500T = CECT 8725T).

Abstract
A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK2-2(T), was isolated from the place where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK2-2(T) grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2.0-3.0% (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain SSK2-2(T) fell within the clade comprising the type strains of species of the genus Maribacter, joining the type strain of Maribacter sedimenticola with which it shared 99.4% similarity. Sequence similarities to the type strains of other Maribacter species were 94.6-98.2%. Strain SSK2-2(T) contained MK-6 as the predominant menaquinone and iso-C17 : 0 3-OH, iso-C15 : 0, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0) as the major fatty acids. The major polar lipids of strain SSK2-2(T) were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-2(T) was 38.2 mol% and mean levels of DNA-DNA relatedness with the type strains of four phylogenetically related species of the genus Maribacter were 11-24%. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK2-2(T) is separate from other Maribacter species. On the basis of the data presented, strain SSK2-2(T) is considered to represent a novel species of the genus Maribacter, for which the name Maribacter confluentis sp. nov. is proposed. The type strain is SSK2-2(T) ( = KCTC 42604(T) = CECT 8869(T)).

Abstract
A Gram-stain-negative, aerobic, non-flagellated, non-gliding and ovoid or rod-shaped bacterium, designated strain W-BA8T, was isolated from a brown algae reservoir on the South Sea, South Korea, and subjected to a polyphasic taxonomic approach. Strain W-BA8T grew optimally at 25 °C, at pH 7.0-7.5 and in the presence of 1.0-2.0% (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain W-BA8T clustered with the type strains of species of the genus Lacinutrix. Strain W-BA8T exhibited 16S rRNA gene sequence similarity values of 94.9-96.5% to the type strains of Lacinutrix species and of less than 95.8% to the type strains of other recognized species. Strain W-BA8T contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C15 : 1 G, iso-C15 : 0 3-OH and iso-C17 : 0 3-OH as major fatty acids. The polar lipid profile of strain W-BA8T contained phosphatidylethanolamine, two unidentified lipids and one unidentified glycolipid as major components. The DNA G+C content of strain W-BA8T was 35 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, revealed that strain W-BA8T is separated from other species of the genus Lacinutrix. On the basis of the data presented, strain W-BA8T is considered to represent a novel species of the genus Lacinutrix, for which the name Lacinutrix undariae sp. nov. is proposed. The type strain is W-BA8T ( = KCTC 42176T = CECT 8671T).

Abstract
A Gram-stain-negative, non-flagellated, non-gliding, aerobic and rod-shaped or ovoid bacterial strain, designated W-BA7(T), was isolated from a brown alga reservoir on the South Sea in South Korea. This strain grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of approximately 2.0% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain W-BA7(T) belonged to the genus Polaribacter, clustering coherently with the type strain of Polaribacter sejongensis, showing 99.3% sequence similarity. Strain W-BA7(T) exhibited 16S rRNA gene sequence similarity of 93.4-98.6% to the type strains of the other species of the genus Polaribacter. Strain W-BA7(T) contained MK-6 as the predominant menaquinone and iso-C15 : 0 3-OH and anteiso-C15 : 0 as the major fatty acids. The major polar lipids of strain W-BA7(T) were phosphatidylethanolamine, three unidentified lipids, one unidentified glycolipid, one unidentified aminolipid and one unidentified aminophospholipid. The DNA G+C content of strain W-BA7(T) was 31.9 mol%, and the mean DNA-DNA relatedness with the type strains of four phylogenetically related species of the genus Polaribacter was 12-27%. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain W-BA7(T) is separated from recognized species of the genus Polaribacter. On the basis of the data presented, strain W-BA7(T) is considered to represent a novel species of the genus Polaribacter, for which the name Polaribacter undariae sp. nov. is proposed. The type strain is W-BA7(T) ( =KCTC 42175(T) =CECT 8670(T)).

Abstract
A Gram-stain-positive, facultatively anaerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, designated BS-12M(T), was isolated from a tidal flat sediment on the South Sea, South Korea. Strain BS-12M(T) grew optimally at 35 °C, at pH 7.0-8.0 and in the presence of 2.0% (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain BS-12M(T) fell within the cluster comprising the type strains of species of the genus Demequina, joining the type strain of Demequina aestuarii with which it shared the highest sequence similarity (98.6%). It exhibited 16S rRNA gene sequence similarity of 96.1-97.9% to the type strains of other species of the genus Demequina. The peptidoglycan type of strain BS-12M(T) was A4β based on L-Orn -L-Ser -D-Glu. Strain BS-12M(T) contained demethylmenaquinone-9(H4) as the major menaquinone and anteiso-C15:0 and C16:0 as the major fatty acids. The major polar lipids of strain BS-12M(T) were phosphatidylinositol and phosphatidylinositolmannoside. The DNA G+C content of strain BS-12M(T) was 70.7 mol% and its DNA-DNA relatedness values with the type strains of five phylogenetically related species of the genus Demequina were 15-34%. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain BS-12M(T) is separate from other species of the genus Demequina. On the basis of the data presented, strain BS-12M(T) is considered to represent a novel species of the genus Demequina, for which the name Demequina activiva sp. nov. is proposed. The type strain is BS-12M(T) ( =KCTC 29674(T) = NBRC 110675T).

Abstract
A Gram-stain-negative, coccoid- or oval-shaped, gliding bacterial strain, designated HDW-31T, belonging to the class
Alphaproteobacteria
, was isolated from seawater of the Yellow Sea, Korea, and was subjected to a taxonomic study using a polyphasic approach. Strain HDW-31T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain HDW-31T fell within the clade comprising the genus
Altererythrobacter
, clustering with the type strains of
Altererythrobacter luteolus
and
Altererythrobacter gangjinensis
, with which strain HDW-31T exhibited 97.0 and 96.0 % sequence similarity values, respectively. Sequence similarities to the type strains of the other recognized species of the genus
Altererythrobacter
were 93.5–96.0 %. The DNA G+C content was 57.9 mol% and mean DNA–DNA relatedness between strain HDW-31T and the type strain of
A. luteolus
was 5.3 %. Strain HDW-31T contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and C16 : 0 as the major fatty acids. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, a sphingoglycolipid, two unidentified glycolipids and an unidentified lipid. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, demonstrated that strain HDW-31T is distinguishable from recognized species of the genus
Altererythrobacter
. On the basis of the data presented, strain HDW-31T is considered to represent a novel species of the genus
Altererythrobacter
, for which the name Altererythrobacter aestiaquae sp. nov. is proposed. The type strain is HDW-31T ( = KCTC 42006T = CECT 8527T).
