A taxonomic study was carried out on strain 22II14-10F7T, which was isolated from the deep-sea water of the Atlantic Ocean with oil-degrading enrichment. The bacterium was Gram-stain-negative, oxidase- and catalase-positive and rod-shaped. Growth was observed at salinities from 0.5 to 15 % and at temperatures from 4 to 37 °C; it was unable to hydrolyse Tween 40, 80 or gelatin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 22II14-10F7T represented a member of the genus Zunongwangia , with highest sequence similarity of 97.3 % to Zunongwangia profunda SM-A87T, while the similarities to other species were all below 94.0 %. The DNA–DNA hybridization estimate of the similarity between strain 22II14-10F7T and Z. profunda SM-A87T was 27.20±2.43 % according to their genome sequences. The principal fatty acids were iso-C15 : 0, anteiso-C15 : 0 , iso-C15 : 1 G, iso-C17 : 0 3-OH, summed feature 3 (C16 : 1ω7c/ω6c) and summed feature 9 (iso-C17 : 1ω9c or C16 : 0 10-methyl). The G+C content of the chromosomal DNA was 35.5 mol%. The major respiratory quinone was determined to be MK-6. Phosphatidylethanolamine (PE), two aminolipids (AL1 and AL2) and five unknown lipids (L1–L5) were present. The combined genotypic and phenotypic data show that strain 22II14-10F7T represents a novel species of the genus Zunongwangia , for which the name Zunongwangia atlantica sp. nov. is proposed, with the type strain 22II14-10F7T ( = CGMCC1.12470T = LMG 27421T = MCCC 1A06481T).

A taxonomic study was carried out on strain CIC4N-9T, which was isolated from deep-sea water of the Indian Ocean. The bacterium was Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and non-motile. Growth was observed at salinities of 0–9% and at temperatures of 4–41 °C. The isolate was able to degrade gelatin but not aesculin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CIC4N-9T belonged to the genus Pararhodobacter , with the highest sequence similarity to the only recognized species, Pararhodobacter aggregans D1-19T (96.9 %). The average nucleotide identity and estimated DNA–DNA hybridization values between strain CIC4N-9T and P. aggregans D1-19T were 80.4 and 23.0 %, respectively. The principal fatty acids were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0, C18 : 1ω7c 11-methyl, C18 : 0 and C17 : 0. The G+C content of the chromosomal DNA was 66.8 mol%. The sole respiratory quinone was determined to be Q-10. Phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, two unknown phospholipids, four unknown aminolipids and one unknown polar lipid were present. The combined genotypic and phenotypic data show that strain CIC4N-9T represents a novel species within the genus Pararhodobacter , for which the name Pararhodobacter marinus sp. nov. is proposed. The type strain is CIC4N-9T (=MCCC 1A01225T=KCTC 52336T).

A taxonomic study was carried out on strain R8-12T, which was isolated from deep-sea water of the Indian Ocean during the screening of oil-degrading bacteria. The isolate was Gram-stain-negative, oxidase and catalase-positive. Growth was observed at salinities from 0.5 to 15 % (optimum 3 %), at pH from 6–10 (optimum 7–8) and at temperatures from 10 to 42 °C (optimum 28 °C). On the basis of 16S rRNA gene sequence similarity, strain R8-12T was shown to belong to the genus Alcanivorax and to be related to Alcanivorax venustensis DSM 13974T (97.2 %), A. dieselolei B-5T (95.0 %), A. balearicus MACL04T (94.6 %), A. hongdengensis A-11-3T (94.3 %), A. jadensis T9T (93.8 %), A. borkumensis SK2T (93.7 %) and A. pacificus W11-5T (93.7 %). The gyrB sequence similarities between R8-12T and other species of the genus Alcanivorax ranged from 77.9 % to 86.9 %. The major fatty acids were C16 : 0 (31.8 %), C18 : 1ω7c (20.3 %), C19 : 0ω8c cyclo (15.8 %) and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) (8.9 %). The polar lipids were phosphatidylglycerol (PG), phosphatidylethanolamine (PE), two aminolipids (AL1–AL2) and two phospholipids (PL1–PL2). Three alkane hydroxylase (alkB) genes were identified in the genome. The G+C content of the chromosomal DNA was 66.1 mol%. DNA–DNA hybridization showed that strain R8-12T and A. venustensis DSM 13974T had a DNA–DNA relatedness of 63±3 %. According to its phenotypic features and fatty acid composition as well as the 16S rRNA and gyrB gene sequences, the novel strain represents a member of the genus Alcanivorax , but could be easily distinguished from all other known species of the genus Alcanivorax described to date. The name Alcanivorax marinus sp. nov. is proposed, with the type strain R8-12T ( = MCCC 1A00382T = LMG 24621T = CCTCC AB 208234T).

A novel mesophilic, hydrogen-, and sulfur-oxidizing bacterium, designated strain ST-419T, was isolated from a deep-sea hydrothermal vent plume on the Carlsberg Ridge of the Northwestern Indian Ocean. The isolate was a Gram-staining-negative, non-motile and coccoid to oval-shaped bacterium. Growth was observed at 4–50 °C (optimum 37 °C), pH 5.0–8.6 (optimum pH 6.0) and 1.0–5.0 % (w/v) NaCl (optimum 3.0 %). ST-419T could grow chemlithoautotrophically with molecular hydrogen, sulfide, elemental sulfur and thiosulfate as energy sources. Molecular oxygen, nitrate and elemental sulfur could be used as electron acceptors. The predominant fatty acids were C16 : 1ω7c, C18 : 1ω7c and C16 : 0.

The bacterium was Gram-stain-positive, oxidase- and catalase-positive and rod-shaped. Growth was observed at salinity of 0–15.0% NaCl and at temperatures of 10–45 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PA15-N-34T belonged to the genus Alcanivorax , with the highest sequence similarity to Alcanivorax profundi MTEO17T (97.7 %), followed by Alcanivorax nanhaiticus 19 m-6T (97.3 %) and 12 other species of the genus Alcanivorax (93.4 %–97.0 %). The average nucleotide identity and DNA–DNA hybridization values between strain PA15-N-34T and type strains of the genus Alcanivorax were 71.46–81.78% and 18.7–25.2 %, respectively. The principal fatty acids (>10 %) were summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c; 31.2 %), C16 : 0 (25.0 %) and summed feature 3 (14.6 %). The DNA G+C content was 57.15 mol%. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, four unidentified aminolipids and three unidentified lipids. The novel strain can be differentiated from its closest type strain by a negative test for urease and the presence of diphosphatidylglycerol and aminolipid. The combined genotypic and phenotypic data show that strain PA15-N-34T represents a novel species within the genus Alcanivorax , for which the name Alcanivorax sediminis sp. nov. is proposed, with the type strain PA15-N-34T (=MCCC 1A14738T=KCTC 72163T).

A novel Gram-stain-positive, motile, aerobic, non-spore-forming and slender rod-shaped actinobacterium, designated strain CTD02-10-2T, was isolated from deep sea water of the Indian Ocean. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CTD02-10-2T was grouped into a separated branch with Chryseoglobus frigidaquae JCM 14730T (98.4 % nucleotide sequence identity). The respiratory quinones were menaquinones with 11, 12, 13 and 14 isoprene units and anteiso-C15 : 0, iso-C16 : 0, anteiso-C15 : 1 A and anteiso-C17 : 0 were the major fatty acids. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and three unknown glycolipids. The genome of strain CTD02-10-2T was 2.59 Mb, with a DNA G+C content of 69.6 mol% and contained genes involved in the biosynthesis of alkylresorcinol, ansamycin, and carotenoids. In silico DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between strain CTD02-10-2T and C. frigidaquae JCM 14730T were clearly below the thresholds used for the delineation of a new species. Based on its morphological and chemotaxonomic characteristics, as well as genotypic data, strain CTD02-10-2T was classified as a novel species of the genus Chryseoglobus , for which the name Chryseoglobus indicus sp. nov. is proposed. The type strain is CTD02-10-2T (=JCM 33842T=MCCC 1A16619T).
