An aerobic, Gram-stain-negative, rod-shaped and non-motile bacterium, JS14SB-1T, was isolated from the surface freshwater of the Jiulong River, PR China. Strain JS14SB-1T grew at 15–38 °C (optimum, 28–35 °C), at pH 6.0–9.0 (optimum pH 7.0) and in the presence of 1.0–7.0 % (w/v) NaCl [optimum 3.0–5.0 % (w/v)]. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain JS14SB-1T was affiliated to the genus Kordia, sharing low similarities (95.1–97.1 %) to all type strains of species of this genus. The digital DNA–DNA hybridization (DDH) value between strain JS14SB-1T and the closely related strain Kordia jejudonensis SSK3-3T was 20.70 ± 2.33 % and far below the 70 % DDH value taken as the gold standard for delineation of bacterial species. The major fatty acids were identified as iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids were phosphatidylethanolamine, glycolipid, aminolipid, several unidentified phospholipids and lipids. The predominant menaquinone was MK-6. The G+C content of the genomic DNA was 33.8 mol%. Based on the phenotypic, phylogenetic and chemotaxonomic distinctiveness, strain JS14SB-1T is considered to represent a novel species of the genus Kordia, for which the name Kordia zhangzhouensis sp. nov. is proposed; the type strain is JS14SB-1T ( = MCCC 1A00726T = KCTC 42140T).

A Gram-negative, motile, rod-shaped bacterium (WSF2T) was isolated from coastal seawater of the Boso Peninsula in Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain WSF2T represented a separate lineage within the genus Pseudovibrio. The DNA G+C content of strain WSF2T was 51.7 mol%. DNA–DNA hybridization values between strain WSF2T and the type strains of Pseudovibrio species were significantly lower than those accepted as the phylogenetic definition of a species. Furthermore, some biochemical characteristics indicated that strain WSF2T differed from other Pseudovibrio species. Based on these characteristics, it is proposed that the isolate represents a novel species, Pseudovibrio japonicus sp. nov. The type strain is WSF2T (=IAM 15442T=NCIMB 14279T=KCTC 12861T).

Abstract A Gram-stain-negative, aerobic, rod-shaped bacterium, designated strain TRM85114T, was isolated from Jincaotan in Pamir, PR China. We found it has the ability to degrading 1-naphthylamine. Strain TRM85114T grows at 4-40 °C (optimum, 30 °C), at pH 6.0-9.0 (optimum, pH 6.0-7.0) and with 3%-15% (w/v) NaCl (optimum, 3%-6%). Phylogenetic analysis of 16S rRNA gene sequences revealed that strain TRM85114T is affiliated with the genus Halomonas, sharing high sequence similarity (97.3%) with the type strain of Halomonas korlensis CGMCC 1.6981T. The major fatty acids of strain TRM85114T are C12:0 3-OH, C16:0, C17:0 cyclo, C19:0 cyclo ω8c, summed feature 3 (C16:1 ω7c and/or C16:1 ω6c) and summed feature 8 (C18:1 ω6c and/or C18:1 ω7c). The predominant respiratory quinone is Q-7. The genomic DNA G + C content of strain TRM85114T was determined to be 61.6 mol%. Calculating the average nucleotide identities and the digital DNA-DNA hybridization values between strain TRM85114T and the related type Halomonas strains further revealed that TRM85114T represented a novel species of the genus Halomonas. The name Halomonas jincaotanensis sp. nov. is proposed. The type strain is TRM85114T (CCTCC AB 2021006T =LMG 32311T).

Emended Description

Strain JC268T was isolated from pebbles collected from a dam located in Lalitpur, Uttar Pradesh, India. Cells of strain JC268T were coccoid, appeared in pairs/triads/tetrads or short chains and were Gram-stain-positive, non-spore-forming, non-motile and obligately aerobic. Strain JC268T was catalase- and oxidase-positive and utilized citrate for growth. The genomic DNA G+C content of strain JC268T was 65.3 mol%. The cell-wall peptidoglycan contained l-lysine–l-serine–d-aspartic acid as interpeptide bridge with the type A4α. The major menaquinone was MK-8(H4). Major (>10 %) fatty acids were iso-C16 : 0, iso-C16 : 1H and anteiso-C17 : 1ω9c. Diphosphatidylglycerol, phosphoglycolipid, phosphatidylinositol, glycolipid, four unidentified lipids, an amino lipid and phospholipid were the polar lipids of strain JC268T. EzTaxon-e blast search of 16S rRNA gene sequences showed that strain JC268T has highest similarity to Barrientosiimonas humi 39T (98.65 %) and Tamlicoccus marinus MSW-24T (97.8 %) of the family Dermacoccaceae. Genome reassociation (based on DNA–DNA hybridization) of strain JC268T with Barrientosiimonas humi CGMCC 4.6864T ( = 39T) and T. marinus KCTC 19485T ( = MSW-24T) yielded values of 32.5 ± 2 % and 27.3 ± 2 %, respectively. Based on the data from phylogenetic and polyphasic taxonomic analyses, strain JC268T represents a novel species of the genus Barrientosiimonas for which the name Barrientosiimonas endolithica sp. nov., is proposed. The type strain of Barrientosiimonas endolithica is JC268T ( = KCTC 29672T = NBRC 110608T). Our data suggest that T. marinus should be reclassified within the genus Barrientosiimonas. Thus, a reclassification is proposed for T. marinus, the type and only species of the genus Tamlicoccus, as Barrientosiimonas marina comb. nov., which implies the emendation of the description of the genus Barrientosiimonas.
