Abstract
Strain AA17T was isolated from an apparently healthy fragment of Montipora capitata coral from the reef surrounding Moku o Lo'e in Kāne'ohe Bay, O'ahu, Hawai'i, USA, and was taxonomically evaluated using a polyphasic approach. Comparison of a partial 16S rRNA gene sequence found that strain AA17T shared the greatest similarity with Aestuariibacter halophilus JC2043T (96.6%), and phylogenies based on 16S rRNA gene sequences grouped strain AA17T with members of the Aliiglaciecola, Aestuariibacter, Lacimicrobium, Marisediminitalea, Planctobacterium, and Saliniradius genera. To more precisely infer the taxonomy of strain AA17T, a phylogenomic analysis was conducted and indicated that strain AA17T formed a monophyletic clade with A. halophilus JC2043T, divergent from Aestuariibacter salexigens JC2042T and other related genera. As a result of monophyly and multiple genomic metrics of genus demarcation, strain AA17T and A. halophilus JC2043T comprise a distinct genus for which the name Fluctibacter gen. nov. is proposed. Based on a polyphasic characterisation and identifying differences in genomic and taxonomic data, strain AA17T represents a novel species, for which the name Fluctibacter corallii sp. nov. is proposed. The type strain is AA17T (= LMG 32603 T = NCTC 14664T). This work also supports the reclassification of A. halophilus as Fluctibacter halophilus comb. nov., which is the type species of the Fluctibacter genus. Genomic analyses also support the reclassification of Paraglaciecola oceanifecundans as a later heterotypic synonym of Paraglaciecola agarilytica.

Abstract
An aerobic Gram-stain-negative, curved rod-shaped and non-spore-forming bacterial strain (NBU2194T) was isolated from seawater collected in an intertidal zone in Ningbo, Zhejiang Province, PR China. It was motile though a single polar flagellum and grew at 20-42 °C (optimum, 30 °C), in 0-2.0 % NaCl (0 %, w/v) and at pH 5.0-9.0 (pH 6.0-7.0). The sole respiratory quinone was ubiquinone-8. The major cellular fatty acids were C16 : 0, C16 : 1 ω7c and/or C16 : 1 ω6c. The polar lipids contained diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, one unidentified phospholipid and two unidentified aminophosphoglycolipids. A phylogenetic analysis based on 16S rRNA gene sequences and 65 genomic core genes showed that strain NBU2194T formed a distinct lineage in the family Alteromonadaceae. The genome of strain NBU2194T was 4 913 533 bp with a DNA G+C content of 43.9 mol% and coded 3895 genes, 12 rRNA genes and 47 tRNA genes. The average nucleotide identity, amino acid identity and digital DNA-DNA hybridization values between strain NBU2194T and related species of Alteromonadaceae were below the threshold limit for prokaryotic species delineation. NBU2194T could be distinguished from other genera in the family Alteromonadaceae based on phenotypic, chemotaxonomic and genomic characteristics. On the basis of the polyphasic taxonomic evidence collected in this study, strain NBU2194T is considered to represent a novel genus and species in the family Alteromonadaceae, for which the name Paraneptunicella aestuarii is proposed. The type strain is NBU2194T (=KCTC 82442T=GDMCC 1.2217T).

Abstract
Strain GS-14T was isolated from a mangrove sediment sample collected at Beilun Estuary National Nature Reserve, Guangxi Province, PR China. Cells were Gram-stain-negative, strictly aerobic and rod-shaped with a polar flagellum. Optimal growth occurred in the presence of 3-6 % (w/v) NaCl, at pH 6-8 and at a temperature of 37 °C. The predominant polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Ubiquinone 8 (Q-8) was the sole respiratory quinone. The major fatty acids (>10 % of the total fatty acids) were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The DNA G+C content was 47.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain GS-14T had the highest sequence similarity to Aestuariibacter aggregatus WH169T (96.63 %), Aliiglaciecola coringensis AK49T (96.56 %) and Alteromonas lipolytica JW12T (96.22 %). In addition, the OrthoANIu value and dDDH values calculated from the genomes of strain GS-14T and A. aggregatus WH169T were 79.5 and 21.9 %, respectively. Based on the polyphasic taxonomic results, strain GS-14T is considered to represent a novel species in a new genus, for which the name Marisediminitalea mangrovi gen. nov., sp. nov. is proposed. The type strain of Marisediminitalea mangrovi is GS-14T (=KCTC 72401T=MCCC 1K03622T). Because Aestuariibacter aggregatus WH169T clustered with strain GS-14T in the phylogenetic trees and was clearly separated from the two species within the genus Aestuariibacter, it is reclassified as a member of the genus Marisediminitalea as Marisediminitalea aggregata comb. nov. (type strain WH169T=CGMCC 1.8995T=LMG 25283T). The type species of the genus Marisediminitalea is Marisediminitalea aggregata gen. nov., comb. nov.

Abstract
A Gram-stain-negative, aerobic, short rod-shaped bacterium with a single polar flagellum, designated strain S27-2T, was isolated from surface seawater from the Indian Ocean. Growth was observed in 0-12.0 % (w/v) NaCl with an optimum of 0.5-2.0 % (w/v) NaCl, pH 6.0-9.0 with an optimum of pH 7.0, and growth temperature of 10-41 °C with an optimum of 25-37 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S27-2T belonged to the family Alteromonadaceae and formed a distinct lineage with the type strain of Pseudobowmanella zhangzhouensis. Levels of 16S rRNA gene sequence similarity between strain S27-2T and members of related genera included in the trees ranged from 86.7 to 93.8 %. Strain S27-2T contained Q-8 as the predominant ubiquinone. The principal fatty acids (>10 %) were C16 : 0 (22.1 %), C16 : 1ω7c/ω6c (22.7 %) and C18 : 1ω7c/ω6c (20.1 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, one unidentified phospholipid and two unknown lipids. The G+C content of strain S27-2T was 43.7 mol%. On the basis of the polyphasic taxonomic evidence presented in this study, strain S27-2T should be classified as a novel species in a new genus within the family Alteromonadaceae, for which the name Neptunicella marina gen. nov., sp. nov. is proposed, with the type strain S27-2T (= KCTC52335T=MCCC 1A02149T).

Abstract
A novel bacterial strain, S66T, was isolated from eelgrass collected on the coastline of Zealand, Denmark. Polyphasic analyses involving phenotypic, phylogenetic and genomic methods were used to characterize strain S66T. The strain was Gram-reaction-negative, rod-shaped, aerobic, and displayed growth at 10-25 °C (optimum 20-25 °C) and at pH 7-9 (optimum pH 7.5). Furthermore, strain S66T grew on seaweed polysaccharides agar, agarose, porphyran, κ-carrageenan, alginate and laminarin as sole carbon sources. Major fatty acids were C16 : 0, C16 : 1ω7c and C18 : 1ω7c. The respiratory quinone was determined to be Q-8, and major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content was determined to be 42.2 mol%. Phylogenetic analyses based on the 16S rRNA gene and GyrB sequence comparisons showed that the bacterium was affiliated with the genus Paraglaciecola within the family Alteromonadaceae of the class Gammaproteobacteria. The percentage similarity between the 16S rRNA gene and GyrB sequences of strain S66T and other members of the genus Paraglaciecola were 94-95 % and 84-85 %, respectively. Based on the genome sequence of S66T, the average nucleotide identity (ANI) between strain S66T and other members of the genus Paraglaciecola was 77-80 %, and DNA-DNA hybridization prediction showed values of less than 24 % relatedness, respectively, between S66T and other species of the genus Paraglaciecola. The phenotypic, phylogenetic and genomic analyses support the hypothesis that strain S66T represents a novel species of the genus Paraglaciecola, for which the name Paraglaciecola hydrolytica sp. nov. is proposed. The type strain is S66T (=LMG 29457T=NCIMB 15060T=DSM 102834T).

Abstract
A bacterial strain designated K7T was isolated from the South China Sea and characterized using a polyphasic taxonomic approach. Cells of strain K7T were Gram-stain-negative, aerobic, poly-β-hydroxybutyrate-accumulating, motile by means of a monopolar flagellum, non-spore forming rods surrounded by a thick capsule and forming yellow colonies. Growth occurred at 4-35 °C (optimum, 25-30 °C), at pH 5.0-9.0 (optimum, pH 7.0) and with 0.5-10 % (w/v) NaCl [optimum, 1-4 % (w/v)]. The predominant fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The major isoprenoid quinone was Q-8 and the DNA G+C content was 46.5 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, one uncharacterized phospholipid, two uncharacterized aminophospholipids and five uncharacterized lipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain K7T formed a distinct lineage with respect to closely related genera in the family Alteromonadaceae. Strain K7T was most closely related to Aestuariibacter, Aliiglaciecola, Paraglaciecola and Glaciecola, and the levels of 16S rRNA gene sequence similarity with respect to the type species of related genera were less than 95 %. On the basis of the genotypic and phenotypic data, strain K7T represents a novel species of a new genus of the family Alteromonadaceae, for which the name Planctobacterium marinum gen. nov., sp. nov. is proposed. The type strain of Planctobacterium marinum is K7T (=BCRC 80901T=LMG 28835T=KCTC 42657T).

A Gram-stain-negative heterotrophic bacterium, designated GSD6T, capable of growth on aliphatic hydrocarbons as a sole carbon and energy source, was isolated from sea-tidal flat sediment of the Yellow Sea, South Korea. Cells were facultatively aerobic, catalase- and oxidase-positive, motile rods with a single polar flagellum. Growth of strain GSD6T was observed at 4–37 °C (optimum 30 °C), at pH 5.5–9.0 (optimum pH 6.5–7.5) and in the presence of 1–9 % (w/v) NaCl (optimum 2 %). Strain GSD6T contained ubiquinone-8 (Q-8) as the sole isoprenoid quinone and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0, C18 : 1ω7c, C17 : 0 10-methyl and C17 : 1ω8c as the major fatty acids. Phosphatidylethanolamine and phosphatidylglycerol were identified as the major polar lipids. The G+C content of the genomic DNA was 44.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain GSD6T formed a phylogenetic lineage with members of the genus
Aliiglaciecola
. Strain GSD6T was most closely related to
Aliiglaciecola lipolytica
E3T with a 16S rRNA gene sequence similarity of 97.4 %, but their DNA–DNA hybridization value was 39.1±7.1 %. On the basis of phenotypic, chemotaxonomic and molecular features, strain GSD6T represents a novel species of the genus
Aliiglaciecola
, for which the name Aliiglaciecola aliphaticivorans sp. nov. is proposed. The type strain is GSD6T ( = KACC 18129T = JCM 30133T). An emended description of the genus
Aliiglaciecola
is also proposed.

Abstract
A strain, JS7-9(T), which was isolated from the surface freshwater of the Jiulong River, China, was subjected to taxonomic study. The bacterium was Gram-negative, facultatively anaerobic, rod-shaped and motile by means of a single polar flagellum. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JS7-9(T) is affiliated to the family Alteromonadaceae, showing 90.5-94.2 % of 16S rRNA gene sequence similarity with the genera Bowmanella (94.0-94.2 %), Aestuariibacter (93.0-93.5 %), Glaciecola (91.0-93.1 %), Alteromonas (90.5-93.1 %) and Salinimonas (90.6-91.8 %). The major fatty acids were identified as C16:0, Sum In Feature 3 (C16:1 ω7c/ω6c), Sum In Feature 8 (C18:1 ω7c/ω6c) and C17:1 ω8c, and Q-8 as the predominant isoprenoid quinone. Based on the phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain JS7-9(T) is considered to represent a novel species of a novel genus of the family Alteromonadaceae, for which the name Pseudobowmanella zhangzhouensis gen. nov., sp. nov. is proposed, with the type strain JS7-9(T) (=MCCC 1A00758(T) = KCTC 42143(T)).

Abstract
A Gram-negative, rod shaped, motile, aerobic bacterium, designated as strain AK49(T) was isolated from a water sample from a mangrove forest in Coringa village, Andhra Pradesh, India. Strain AK49(T) was observed to form yellow coloured, smooth, circular, convex colonies on marine agar, with entire margins. Cells of strain AK49(T) are 0.5-1.0 µm wide and 1.5-3.5 µm long. Growth was observed at 25-37 °C (optimum 30 °C), 2-6 % NaCl (optimum 2 %) and pH 6-8 (optimum 7). Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain AK49(T) is closely related to two species recently reclassified as members of the genus Aliiglaciecola: Aliiglaciecola lipolytica JCM 15139(T) (sequence similarity 95.43 %) and Aliiglaciecola litoralis JCM 15896(T) (sequence similarity 96.91 %). The major cellular fatty acids of strain AK49(T) were found to include C16:0, C18:1ω7c and summed feature 3 (C16:1ω7c/C15:0 iso-2-OH). The polar lipid content of cell membrane was found to include phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid, an unidentified lipid and an unidentified glycolipid. The genomic DNA G+C content of strain AK49(T) was determined to be 41.9 mol%. Based on the taxonomic methods, including chemotaxonomic, phenotypic and phylogenetic approaches, strain AK49(T) is described here as a novel species belonging to the genus Aliiglaciecola, for which the name Aliiglaciecola coringensis sp. nov. is proposed. The type strain of Aliiglaciecola coringensis sp. nov. is AK49(T) (=MTCC 12003(T )= JCM19197(T)).

Abstract
A Gram-stain-negative, motile, mesophilic, aerobic, rod-shaped bacterium, strain 8-8(T), was isolated from surface seawater at Muroto, Kochi, Japan. The strain exhibited agar-degrading activity. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain fell within the family Alteromonadaceae and clustered distantly with members of the genus Glaciecola (≤ 94.0% similarity). The DNA G+C content was 41.8 mol%. The major fatty acids were C16 : 1ω7c and/or iso-C15 : 0 2-OH, C16 : 0 and C18 : 1ω7c and the major hydroxy fatty acid was C12 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unidentified polar lipid; lysophosphatidylethanolamine and unidentified polar lipids were found as minor components. The major quinone was Q-8. On the basis of phenotypic, genotypic and chemotaxonomic data, strain 8-8(T) represents a novel species of a new genus, for which the name Agaribacter marinus gen. nov., sp. nov. is proposed. The type strain of Agaribacter marinus is 8-8(T) ( = NBRC 110023(T) = LMG 28167(T)).

Abstract
Following phylogenetic analysis based on 16S rRNA gene sequences, together with DNA G+C contents and differential chemotaxonomic and physiological characteristics, a new genus with the name Aliiglaciecola gen. nov. is proposed to more appropriately accommodate two recognized species of the genera
Glaciecola
and
Aestuariibacter
. Accordingly,
[Glaciecola] lipolytica
and [
Aestuariibacter] litoralis
should be reassigned to the novel genus as Aliiglaciecola lipolytica comb. nov. (type strain, E3T = JCM 15139T = CGMCC 1.7001T) and Aliiglaciecola litoralis comb. nov. (type strain, KMM 3894T = JCM 15896T = NRIC 0754T), respectively. Aliiglaciecola lipolytica is proposed as the type species of this new genus. Physiologically, the combined characteristics of positive reactions for nitrate reduction and growth at 4 °C and 36 °C distinguish the new genus from the genera
Aestuariibacter
and
Glaciecola
by one to three traits. Moreover, the new genus is also distinguished from the genus
Glaciecola
by the fatty acid profile and distinguished from the genus
Aestuariibacter
by the differences of major isoprenoid quinone (MK-7 vs Q-8) and DNA G+C content (40.8–43.0 mol% vs 48.0–54.0 mol%).
