Echinimonas agarilytica gen. nov., sp. nov., a new gammaproteobacterium isolated from the sea urchin Strongylocentrotus intermedius

Neiella litorisoli sp. nov., an alginate lyase: producing bacterium from South China Sea, and proposal of Echinimonadaceae fam. nov. in the order Alteromonadales

A Gram-stain-negative, rod-shaped bacterium, designated HB171785^T, was isolated from soil sample collected from Qishui Bay, Hainan, China. The strain grew optimally at pH 7-8, 37-40 °C and with NaCl 3-4%. The predominant isoprenoid quinone was found to be Q-8 and the major fatty acids were C_16:0, C_16:1 ω7c/C_16:1 ω6c, C_18:1 ω7c/C_18:1 ω6c and C_12:0 3OH. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The size of the draft genome was 4.32 Mbp with G + C content 49.7%. Phylogenetic analysis of 16S rRNA gene sequence indicated that the closest phylogenetically related species were Neiella marina j221^T, "Neiella holothuriorum" 126 and Echinimonas agarilytica KMM 6351^T with the similarities of 98.2, 96.0 and 95.0%, respectively. The phylogenetic tree based on 16S rRNA gene and phylogenomic tree based on core genome showed that strain HB171785^T clustered together with N. marina j221^T, with the highest values of average nucleotide identity (82.9%) and digital DNA-DNA hybridization (25.4%). The combined phylogenetic relatedness, phenotypic and genotypic features supported the conclusion that strain HB171785^T represents a novel species of the genus Neiella, for which the name Neiella litorisoli sp. nov. is proposed. The type strain is HB171785^T (= MCCC 1K04625^T = KCTC 82319^T). In addition, Echinimonadaceae fam. nov. in the order Alteromonadales was proposed.

Vibrio amylolyticus sp. nov. and Vibrio gelatinilyticus sp. nov., two marine bacteria isolated from surface seawater of Qingdao

Two Gram-stain-negative, oxidase-positive, facultative anaerobic and rod-shaped motile bacteria, designated strains ZSDZ34 and ZSDE26, were isolated from offshore surface seawater collected near Qingdao. Phylogenetic analysis based on 16S rRNA gene sequences placed ZSDE26^T and ZSDZ34^T within the genus Vibrio, family Vibrionaceae, class Gammaproteobacteria. Strain ZSDE26^T was most closely related to Vibrio gallaecicus VB 8.9^T with 97.3 % sequence similarity, whereas ZSDZ34^T was most closely related to Vibrio aestuarianus subsp. cardii DSM 109723^T with 97.8 % sequence similarity. Strain ZSDE26^T grew with 1-5 % (w/v) NaCl (optimum, 4 %), at 16-28 °C (optimum, 28 °C) and at pH 6.0-9.0 (optimum, pH 7.0). Growth of strain ZSDZ34^T occurred with 1-6 % (w/v) NaCl (optimum, 3 %), at 16-37 °C (optimum, 28 °C) and at pH 6.0-9.0 (optimum, pH 7.0). Both strains shared the same major fatty acid components (more than 10 % of total fatty acids) of summed feature 3 (C_16 : 1 ω7c and/or C_16 : 1 ω6c), summed feature 8 (C_18 : 1 ω7c and/or C_18 : 1 ω6c) and C_16 : 0. Additionally, strain ZSDZ34^T contained a higher proportion of iso-C_16 : 0. The DNA G+C contents of strains ZSDE26^T and ZSDZ34^T were 42.8 and 44.5 mol%, respectively. On the basis of the results of polyphasic analysis, ZSDE26^T and ZSDZ34^T are considered to represent novel species within the genus Vibrio, for which the names Vibrio amylolyticus sp. nov. (type strain, ZSDE26^T=KCTC 82890^T=MCCC 1K06290^T) and Vibrio gelatinilyticus sp. nov. (type strain, ZSDZ34^T=KCTC 82888^T=MCCC 1K06292^T) are proposed, respectively.

Neiella holothuriorum sp. nov., isolated from the gut of a sea cucumber Apostichopus japonicus

A Gram-stain negative, aerobic, rod-shaped bacterium, designated 126^T, was isolated from the intestinal content of a sea cucumber, Apostichopus japonicus, in China. Strain 126^T was found to grow optimally at 25-28 °C and pH 7.5-8.0 in marine 2216 E medium, with tolerance of 1-7% (w/v) NaCl. Strain 126^T is motile by means of one to several polar flagella. The dominant fatty acids of strain 126^T were identified as C_16:1 ω7c/C_16:1 ω6c (29.5%), C_18:1 ω7c/C_18:1 ω6c (19.8%) and C_16:0 (16.7%). The respiratory quinone was found to be Q-8. The polar lipid profile was found to be mainly composed of phosphatidylglycerol and phosphatidylethanolamine. The total length of the draft genome is approximately 4.2 × 10⁶ bp, encoding 3655 genes and 3576 coding sequences. The G + C content of the genomic DNA is 48.0%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 126^T belongs to the genus Neiella and is closely related to Neiella marina J221^T (96.5%). Genomic comparisons of 126^T to N. marina J221^T revealed that they had similar genome size, G + C content and complement of clusters of orthologous groups. However, average nucleotide identity and digital DNA-DNA hybridization values between strains126^T and N. marina J221^T was 75.5% and 19.7%, which could distinguish the strains. On the basis of these phenotypic and genotypic data, strain 126^T is concluded to represent a novel species, for which the name Neiella holothuriorum sp. nov. is proposed. The type strain is 126^T (= GDMCC 1.2530^T = KCTC 82829^T).

Veronia nyctiphanis gen. nov., sp. nov., Isolated from the Stomach of the Euphausiid Nyctiphanes simplex (Hansen, 1911) in the Gulf of California, and Reclassification of Enterovibrio pacificus as Veronia pacifica comb. nov

The bacterial strain 42Xb2 ^T was isolated from a female adult krill Nyctiphanes simplex infected with the apostome parasitoid ciliate Pseudocollinia brintoni in January 2007 in the Gulf of California. The strain has the morphological, phenotypic, and molecular characteristics of the bacteria of the family Vibrionaceae. The 16S rRNA gene sequence has a similarity of 97.7% with Enterovibrio pacificus SW014 ^T and 96.1% similarity with Enterovibrio norvegicus LMG 19839 ^T. A phylogenomic and a multilocus sequence analyses placed this strain close to the genera Enterovibrio, Grimontia, and Salinivibrio, but clearly forming a separate branch from these bacterial genera. Genomic analyses presented further support this result. A novel genus Veronia gen. nov. and a species Veronia nyctiphanis sp. nov. is here described with CAIM 600 ^T (= DSM 24592 ^T = CECT 7578 ^T) as the type strain. Morphological, physiological, and genetic evidence presented here support the unification of Enterovibrio pacificus and Veronia nyctiphanis in the new genus Veronia. Enterovibrio pacificus is reclassified as Veronia pacifica. V. pacifica is assigned as the type species of the new genus Veronia.Genome Sequencing Data The GenBank/EMBL/DDBJ accession numbers for the genome sequence of Veronia nyctiphanis CAIM 600 ^T is PEIB01 and of Enterovibrio pacificus CAIM 1920 ^T is LYBM01. The 16S rRNA gene sequence of V. nyctiphanis CAIM 600 ^T is JX129353.

Vibrio japonicus sp. nov., a novel member of the Nereis clade in the genus Vibrio isolated from the coast of Japan

A novel Vibrio strain, JCM 31412^T, was isolated from seawater collected from the Inland Sea (Setonaikai), Japan, and characterized as a Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, motile, ovoid-shaped bacterium with one polar flagellum. Based on 16S rDNA gene identity, strain JCM 31412^T showed a close relationship with type strains of Vibrio brasiliensis (LMG 20546^T, 98.2% identity), V. harveyi (NBRC 15634^T, 98.2%), V. caribbeanicus (ATCC BAA-2122^T, 97.8%) and V. proteolyticus (NBRC 13287^T, 97.8%). The G+C content of strain JCM 31412^T DNA was 46.8%. Multi-locus sequence analysis (MLSA) of eight loci (ftsZ, gapA, gyrB, mreB, pyrH, recA, rpoA and topA; 5535bp) further clustered strain JCM 31412^T in the Nereis clade, genus Vibrio. Phenotypically, strain JCM 31412^T differed from the closest related Vibrio species in its utilization of melibiose and raffinose, and its lack of casein and gelatin hydrolysis. It was further differentiated based on its fatty acid composition, specifically properties of C_12:03OH and summed features, which were significantly different from those of V. brasiliensis, V. nigripulchritudo and V. caribbeanicus type strains. Overall, the results of DNA-DNA hybridization, and physiological and biochemical analysis differentiated strain JCM 31412^T from other described species of the genus Vibrio. Based on these polyphasic taxonomic findings, it was therefore concluded that JCM 31412^T was a novel Vibrio species, for which the name Vibrio japonicus sp. nov. was proposed, with JCM 31412^T (= LMG 29636^T = ATCC TSD-62^T) as the type strain.

List of new names and new combinations previously effectively, but not validly, published

The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper, to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below, and these authors’ names will be included in the author index of the present issue. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
