An alkaliphilic and halotolerant Gram-stain-positive bacterium, which was isolated from sediment samples from the South China Sea, was subjected to a taxonomic study. The isolate, strain L1T, grew well at a wide range of temperatures and pH values, 10.0–45.0 °C and pH 6–11, with optima at 30 °C and pH 9.0, respectively. The growth of strain L1T occurred at total salt concentrations of 0–10 % (w/v) with an optimum at 2 % (w/v). Phylogenetic analysis based on 16S rRNA sequence comparison indicated that the isolate represented a member of the genus Bacillus . The strains most closely related to strain L1T were Bacillus nanhaiisediminis JCM 16507T, Bacillus halodurans DSM 497T and Bacillus pseudofirmus DSM 8715T, with 16S rRNA similarities of 96.5 %, 95.9 % and 95.7 %, respectively. DNA–DNA hybridization of strain L1T with the type strains of the most closely related species, B. nanhaiisediminis JCM 16507T, B. halodurans DSM 497T and B. pseudofirmus DSM 8715T, showed reassociation values of about 21.7 %, 14.3 % and 13.9 %, respectively. The DNA G+C content of strain L1 T was 40.76 mol%. The predominant isoprenoid quinone was menaquinone 7 (MK-7). The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant cellular fatty acids of strain L1T were iso-C14 : 0 and anteiso-C15 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Based on the phenotypic and phylogenetic characteristics, it is proposed that strain L1T ( = JCM 18543T = DSM 26145T) should be classified as the type strain of Bacillus ligniniphilus sp. nov.

A novel marine actinomycete, designated LHW63021T, was isolated from a marine sponge, genus Craniella, collected in the South China Sea. A polyphasic approach was applied to characterize the taxonomic position of this strain. The strain was found to have scarce aerial mycelia that differentiated into spore chains. The cell-wall hydrolysates contained meso-diaminopimelic acid as the diagnostic diamino acid. Glucose, galactose, mannose and madurose were found in the whole-cell hydrolysates. The dominant polar lipids were phosphatidylinositol and diphosphatidylglycerol. MK-9(H6) and MK-9(H8) were the predominant menaquinones. The major fatty acids were iso-C16 : 0, iso-C18 : 0, 10-methyl C17 : 0 and C18 : 1 ω9c. The DNA G+C content based on the draft genome sequence was 72.0 mol%. 16S rRNA gene sequence analysis indicated that strain LHW63021T was a member of the genus Actinomadura and had the highest similarity to Actinomadura echinospora DSM 43163T (97.3 %). Phylogenetic trees supported their close relationship. The average nucleotide identity and digital DNA–DNA hybridization values between the whole genome sequences of strain LHW63021T and A. echinospora DSM 43163T were 79.13 and 23.20 %, respectively. The evidence from the polyphasic study shows that strain LHW63021T represents a novel species of the genus Actinomadura , for which the name Actinomadura craniellae sp. nov. is proposed. The type strain is LHW63021T (=DSM 106125T=CCTCC AA 2018015T).

A novel, aerobic, heterotrophic, orange-pigmented, Gram-staining-negative, rod-shaped, gliding bacterial strain, designated JLT2000T, was isolated from surface water of the South China Sea. The strain was oxidase- and catalase-positive. The major cellular fatty acids of strain JLT2000 T were C12 : 0, iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 0 3-OH, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 0. MK-7 was the major respiratory quinone and the major polar lipids were phosphatidylcholine and phosphatidylethanolamine. The genomic DNA G+C content of strain JLT2000T was 37.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JLT2000T formed a branch within the genus Marivirga , but was clearly separated from the two established species of this genus, Marivirga tractuosa and Marivirga sericea . The 16S rRNA gene sequence similarity of strain JLT2000T with the type strains of these two species was 95.8 % and 96.1 %, respectively. Strain JLT2000T had a shorter cell length and wider growth range in different temperatures and salinities than those of Marivirga tractuosa NBRC 15989T and Marivirga sericea NBRC 15983T. In addition, strain JLT2000T could utilize more carbon sources and hydrolyse more polymers than Marivirga tractuosa NBRC 15989T and Marivirga sericea NBRC 15983T. Based on this polyphasic analysis, strain JLT2000T represents a novel species of the genus Marivirga , for which the name Marivirga lumbricoides sp. nov. is proposed. The type strain is JLT2000T ( = JCM 18012T = CGMCC 1.10832T).

A novel bacterium, designated strain KXZD1103T, was isolated from sediment collected at a cold seep field of the Formosa Ridge in the South China Sea. Cells were Gram-stain-negative, facultatively anaerobic, motile, oxidase- and catalase-positive, and grew optimally at 28 °C, pH 6.0–pH 7.0 and in the presence of 1–3 % (w/v) NaCl. The major cellular fatty acids were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c) and C16 : 0. The major respiratory ubiquinone was Q-8. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Analysis of 16S rRNA gene sequences revealed that strain KXZD1103T grouped with members of the genus Nitrincola , with Nitrincola lacisaponensis 4CAT (98.1 % sequence similarity) and Nitrincola schmidtii R4-8T (97.7 %) as its closest neighbours. Genome sequencing revealed a genome size of 4.17 Mb and a DNA G+C content of 50.1 %. Genomic average nucleotide identity values for strain KXZD1103T with the type strains within the genus Nitrincola ranged from 71.0 to 75.7 %, while the in silico DNA–DNA hybridization values for strain KXZD1103T with these strains ranged from 16.1 to 21.6 %. On the basis of the results of phylogenetic, phenotypic and chemotaxonomic analyses, strain KXZD1103T is considered to represent a novel species of the genus Nitrincola , for which the name Nitrincola iocasae sp. nov. is proposed. The type strain is KXZD1103T (=KCTC 72678T=MCCC 1K04283T).

A Gram-stain-negative, aerobic, rod-shaped and motile bacterial strain, designated L53-10-65T, was isolated from deep seawater of the South China Sea. Strain L53-10-65T was found to grow at 4–41 °C (optimum, 28 °C), at pH 5.0–9.0 (pH 7.0–8.0) and in 0–7 % (w/v) NaCl (2 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain L53-10-65T fell within the genus Devosia , with the highest similarity to Devosia indica IO390501T (98.4 %), followed by ‘ Devosia lucknowensis ’ L15T (97.7 %) and Devosia riboflavina IFO 13584T (96.8 %). The digital DNA–DNA hybridization (dDDH) values between strain L53-10-65T and the three relatives above were 43.7, 21.5 and 20.9 %, respectively; the average nucleotide identity (ANI) values were 91.3, 78.4 and 76.8 %, respectively. These values were below the 70 % dDDH and 95–96 % ANI thresholds for bacterial species delineation. The major cellular fatty acids of strain L53-10-65T were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C18 : 1 ω7c 11-methyl and C16 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and glycolipids. The respiratory quinone was identified as Q-10. The DNA G+C content of strain L53-10-65T was 61.3 mol%. Based on the results of phylogenetic analysis and distinctive phenotypic characteristics, strain L53-10-65T is concluded to represent a novel species of the genus Devosia , for which the name Devosia marina sp. nov. is proposed. The type strain of the species is L53-10-65T (=MCCC 1A05139T=KCTC 72888T). Moreover, we propose that Devosia subaequoris is a later heterotypic synonym of Devosia soli based on the present results.

Blue holes are unique geomorphological units characterized by steep redox and biogeochemical gradients. Yongle Blue Hole is located on the largest atoll (Yongle Atoll) of the western Xisha Islands in the South China Sea. A Gram-stain-negative, facultatively anaerobic, non-motile, non-flagellated marine bacterium with creamy white colonies, designated JC036T, was isolated from Yongle Blue Hole. Cells were short-rod-shaped and catalase-negative. 16S rRNA gene sequence analysis showed that sequence similarities were lower than 91.6 % against all validly named species in the family Prolixibacteraceae ; a reconstructed phylogenetic tree indicated that strain JC036T formed a lineage with strains in the family Prolixibacteraceae . Growth occurred at 4–37 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum, 7.0) and in the presence of 2–6 % (w/v) NaCl (optimum, 3 %). The prevalent isoprenoid quinone of strain JC036T was menaquinone-7 (MK-7). Iso-C15 : 0 and iso-C17 : 0 3-OH were the predominant fatty acids. The major polar lipids included a phospholipid, phosphatidylethanolamine, an aminophospholipid and four unidentified lipids. The genomic DNA G+C content of strain JC036T was 37.8 mol%. Based on physiological and biochemical characteristics and whole genome comparisons, we propose a new genus and species, Puteibacter caeruleilacunae gen. nov., sp. nov., within the family Prolixibacteraceae . The type strain of Puteibacter caeruleilacunae is JC036T (=JCM 33128T=MCCC 1K03579T). From this study, a deeper understanding of the community of the microorganism and their roles in biogeochemical cycles, especially anaerobic bacteria, is provided.

An aerobic, Gram-stain-negative, rod-shaped and non-motile strain (XY-359T) was isolated from the mouth of a marine invertebrate Onchidium species from the South China Sea. It grew at pH 6.0–8.5 (optimum, pH 7.5), at 15−37 °C (optimum, 30 °C) and in the presence of 0.5–4.5 % (w/v) NaCl (optimum, 2.5 %). It could not hydrolyse Tweens 20, 40, 60 or 80 and no flexirubin-type pigments were produced. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid, six unidentified phospholipids and two unidentified polar lipids. The major fatty acids were iso-C17:0 3-OH, iso-C15:1 G and iso-C15:0 3-OH. The respiratory quinone was MK-6. Strain XY-359T showed the greatest degree of 16S rRNA sequence similarity to Flagellimonas algicola AsT0115T (96.54 %), followed by Muricauda flava DSM 22638T (96.27 %). Phylogenetic analysis based on 16S rRNA gene sequences and 31 core genes indicated that strain XY-359T belongs to the genus Muricauda . The genome size of strain XY-359T was 4 207 872 bp, with 39.1 mol% of DNA G+C content. The average nucleotide identity and digital DNA–DNA hybridization values between strain XY-359T and F. algicola AsT0115T were 74.58 % and 18.5 %, respectively, and those between strain XY-359T and M. flava DSM 22638T were 74.2 % and 18.3 %. The combined phenotypic, chemotaxonomic and phylogenetic data suggest that strain XY-359T represents a novel species of the genus Muricauda , for which the name Muricauda onchidii sp. nov. is proposed. The type strain is XY-359T (=MCCC 1K03658T =KCTC 72218T). Moreover, based on the proposal of nesting Spongiibacterium and Flagellimonas within Muricauda by García (Validation List No. 193) and the analyses of phylogenetic trees and average amino acid identities in this study, the transfers of F. algicola , F. pacifica and F. maritima to the genus Muricauda as Muricauda algicola comb. nov., Muricauda parva nom. nov. and M. aurantiaca nom. nov., respectively, are proposed, with an emended description of the genus Muricauda .

Emended Description

A novel marine bacterial strain, HY1T, was isolated from sediment of the South China Sea. The strain was aerobic and heterotrophic and formed saffron yellow-pigmented colonies on marine agar 2216. Cells were non-motile, Gram-negative rods, frequently occurring in chains. blastn searches revealed that the 16S rRNA gene sequence of strain HY1T showed high similarity with those of members of the genera Gillisia (91.7–93.8 %) and Salegentibacter (92.6–93.5 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain clustered with members of both Salegentibacter and Gillisia and phylogenetic trees constructed using three different methods (neighbour-joining, maximum-parsimony and minimum-evolution) indicated that strain HY1T clustered more frequently with members of the genus Salegentibacter. The DNA G+C content of strain HY1T was 44.4 mol% and its major cellular fatty acids (⩾5 % of the total fatty acids) were iso-15 : 1 (5.0 %), iso-15 : 0 (6.8 %), anteiso-15 : 0 (6.4 %), 15 : 0 (10.4 %), iso-16 : 0 (13.5 %), summed feature 3 (comprising iso-15 : 0 2-OH and/or 16 : 1ω7c; 6.3 %), iso-17 : 0 3-OH (5.2 %) and 17 : 0 2-OH (5.0 %). Cells contained menaquinone 6. Based on the phylogenetic and phenotypic analyses, strain HY1T should be classified as representing a novel species within the genus Salegentibacter, for which the name Salegentibacter catena sp. nov. is proposed. The type strain is HY1T (=CGMCC 1.6101T=JCM 14015T). Based on this study and on previously described Salegentibacter species, an emended description of the genus Salegentibacter is given.
