A pink, Gram-stain-negative, motile, halotolerant bacterium with subpolar flagellum, designated strain BH87090T, was isolated from a saline soil sample collected from the south-west coastal area of South Korea (125° 58′ 58.08″ E 34° 45′ 37.32″ N). The isolate formed opaque pink to red colonies on marine agar plates at 30 °C. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sulfoquinovosyl diacylglycerol, phosphatidylcholine and one unidentified phospholipid. The sole respiratory quinone was ubiquinone-10 (Q-10). The major cellular fatty acids were C18 : 1ω7c, C19 : 0 cyclo ω8c, C16 : 0 and 11-methyl C18 : 1ω7c. The genomic DNA G+C content was 61.8 mol%. These chemotaxonomic characteristics were all consistent with specific properties of the genus Roseivivax . Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate affiliated to the cluster with members of the genus Roseivivax in the Roseobacter clade, which suggested that the strain belonged to the genus Roseivivax . However, the low 16S rRNA gene similarities (93.5–95.3 %) of strain BH87090T with all the members of the genus Roseivivax indicated that it represented a novel species of the genus Roseivivax . On the basis of phenotypic and genotypic data, strain BH87090T should be classified as a novel species of the genus Roseivivax . The name Roseivivax roseus sp. nov. is proposed, with strain BH87090T ( = DSM 23042T = KCTC 22650T) as the type strain.

A novel bacterium, designated strain F051-1T, isolated from a seawater sample collected from the coast at Damupo beach in Pohang, Korea, was investigated in a polyphasic taxonomic study. Cells were yellow-pigmented, strictly aerobic, Gram-staining-negative and rod-shaped. The temperature, pH and NaCl ranges for growth were 4–30 °C, pH 6.0–9.0 and 1.0–6.0 % (w/v), respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain F051-1T belongs to the genus Psychroserpens in the family Flavobacteriaceae . Its closest relatives were Psychroserpens burtonensis ACAM 188T (96.8 % 16S rRNA gene sequence similarity) and Psychroserpens mesophilus KOPRI 13649T (95.7 %). The major cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and anteiso-C15 : 0. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, two unidentified aminolipids, one unidentified phospholipid and eight unidentified lipids. The major respiratory quinone was menaquinone-6 and the genomic DNA G+C content of the strain was 33.5 mol%. On the basis of phenotypic, phylogenetic and genotypic data, strain F051-1T represents a novel species within the genus Psychroserpens , for which the name Psychroserpens damuponensis sp. nov. is proposed. The type strain is F051-1T ( = KCTC 23539T  = JCM 17632T).

A Gram-stain-negative, short-rod-shaped bacterium, designated 22DY03T, was isolated from a sediment sample collected from the East Pacific Rise. The isolate required NaCl and grew best with 3–7 % (w/v) sea salts at temperature of between 30 and 35 °C at pH 7.0. It formed non-pigmented colonies and produced exopolysaccharide, but did not produce bacteriochlorophyll a. Strain 22DY03T was positive for hydrolysis of aesculin and Tween 20 and negative for hydrolysis of casein, DNA, gelatin, starch and Tween 40, 60 and 80. The major respiratory quinone was ubiquinone-10. The polar lipid profile consisted of a mixture of phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, diphosphatidylglycerol, two unidentified phospholipids and four unidentified polar lipids. The major fatty acids were C19 : 0 cyclo ω8c, C18 : 1ω7c and 11-methyl C18 : 1ω7c. The genomic DNA G+C content was 64.6 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain 22DY03T should be assigned to the genus Roseivivax . The 16S rRNA gene sequence similarities between the isolate and the type strains of species of the genus Roseivivax were in the range of 94.1–95.8 %. On the basis of phenotypic and genotypic data, it is concluded that strain 22DY03T represents a novel species of the genus Roseivivax , for which the name Roseivivax pacificus sp. nov. (type strain 22DY03T = CGMCC 1.12410T = JCM 18866T) is proposed.

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).

A polyphasic taxonomic study was carried out on strains CHu50b-3-2T and CHu40b-3-1 isolated from a 67 cm-long sediment core collected from the Daechung Reservoir at a water depth of 17 m, Daejeon, Republic of Korea. The cells of the strains were Gram-stain-negative, non-spore-forming, non-motile and rod-shaped. Comparative 16S rRNA gene sequence studies showed a clear affiliation of two strains with γ-Proteobacteria, which showed the highest pairwise sequence similarities to Lysobacter hankyongensis KTce-2T (96.5 %), Lysobacter pocheonensis Gsoil193T (96.3 %), Lysobacter ginsengisoli Gsoil 357T (96.1 %), Lysobacter solanacearum T20R-70T (96.1 %), Lysobacter brunescens KCTC 12130T (95.4 %) and Lysobacter capsici YC5194T (95.3 %). The phylogenetic analysis based on 16S rRNA gene sequences showed that the strains formed a clear phylogenetic lineage with the genus Lysobacter . The major fatty acids were identified as summed feature 9 (iso-C17 : 1  ω9c and/or C18 : 1 10-methyl), iso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The respiratory quinone was identified as ubiquinone Q-8. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The genomic DNA G+C content was determined to be 66.8 mol% (genome) for strain CHu50b-3-2T and 66.4 mol% (HPLC) for strain CHu40b-3-1. Based on the combined genotypic and phenotypic data, we propose that strains CHu50b-3-2T and CHu40b-3-1 represent a novel species of the genus Lysobacter , for which the name Lysobacter profundi sp. nov. is proposed. The type strain is CHu50b-3-2T (=KCTC 72973T=CCTCC AB 2019129T). Besides Lysobacter panaciterrae Gsoil 068T formed a phylogenetic group together with strain Luteimonas aquatica RIB1-20T (EF626688) that is clearly separated from all other known Lysobacter strains. Based on the phylogenetic relationships together with fatty acid compositions, Lysobacter panaciterrae Gsoil 068T should be reclassified as a member of the genus Luteimonas: Luteimonas aquatica comb. nov. (type strain Gsoil 068T=KCTC 12601T=DSM 17927T).

A Gram-negative bacterium, designated S1-65T, was isolated from soil samples collected from a cotton field located in the Xinjiang region of PR China. Results of 16S rRNA gene sequence analysis revealed that strain S1-65T was affiliated to the genus Steroidobacter with its closest phylogenetic relatives being ‘Steroidobacter cummioxidans’ 35Y (98.4 %), ‘ Steroidobacter agaridevorans ’ SA29-B (98.3 %) and Steroidobacter agariperforans KA5-BT (98.3 %). 16S rRNA-directed phylogenetic analysis showed that strain S1-65T formed a unique phylogenetic subclade next to ‘ S. agaridevorans ’ SA29-B and S. agariperforans KA5-BT, suggesting that strain S1-65T should be identified as a member of the genus Steroidobacter . Further, substantial differences between the genotypic properties of strain S1-65T and the members of the genus Steroidobacter , including average nucleotide identity and digital DNA–DNA hybridization, resolved the taxonomic position of strain S1-65T and suggested its positioning as representing a novel species of the genus Steroidobacter . The DNA G+C content of strain S1-65T was 62.5 mol%, based on its draft genome sequence. The predominant respiratory quinone was ubiquinone-8. The main fatty acids were identified as summed feature 3 (C16:1ω6c/C16:1ω7c), C16 : 0 and iso-C15 : 0. In addition, its polar lipid profile was composed of aminophospholipid, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Here, we propose a novel species of the genus Steroidobacter : Steroidobacter gossypii sp. nov. with the type strain S1-65T (=JCM 34287T=CGMCC 1.18736T).

A yellow-pigmented, Gram-stain-negative, rod-shaped, non-spore-forming bacterium designated strain HLJ-RS18T, which could degrade fluorene, was isolated from rice seeds collected from Heilongjiang Province, China. Similarities of full-length of 16S rRNA gene sequences between strain HJL-RS18T and the type strains of the genus Novosphingobium with validly published names ranged from 93.8 to 97.1 %. Phylogenetic analysis with maximum-likelihood and neighbour-joining methods revealed that strain HLJ-RS18T belonged to genus Novosphingobium and strain HLJ-RS18T formed a distinct clade to Novosphingobium chloroacetimidivorans BUT-14T (96.9 % similarity based on 16S rRNA gene). DNA–DNA hybridization of HLJ-RS18T and BUT-14T showed a low relatedness value of 22.4±0.9 %, which indicated that strain HLJ-RS18T represents a novel species of the genus Novosphingobium . The genomic DNA G+C content of strain HLJ-RS18T was 62 mol%. Ubiquinone Q-10 was the major respiratory quinone. Spermidine was the predominant polyamine. Polar lipids consisted mainly of aminophospholipid, phosphatidylglycerol, phosphatidylethanolamine, phospholipid and sphingoglycolipid. The predominant fatty acid composition of HLJ-RS18T were summed 8 (C18 : 1ω7c and/or C18 : 1ω6c, 61.5 %), C16 : 0 (14.2 %), summed 3 (C16 : 1ω7c and/or C16 : 1ω6c, 13.5 %) and C14 : 0 2-OH (6.8 %). Phylogenetic analysis, DNA–DNA hybridization, chemotaxonomic data and phenotypic characteristics support the conclusion that HLJ-RS18T represents a novel species within the genus Novosphingobium . Therefore, we propose the species Novosphingobium fluoreni sp. nov. with HLJ-RS18T ( = DSM 27568T = ACCC19180T) as the type strain.

Four strains assigned the names FT13WT, FT14W, FT58WT and FT68WT were isolated from a subtropical stream in PR China. All the strains were Gram-stain-negative, catalase- and oxidase-positive, rod-shaped and motile with flagella. Comparisons based on 16S rRNA gene sequences showed that strains FT13WT, FT14W, FT58WT and FT68WT belonged to genus Janthinobacterium and shared 16S rRNA gene similarities in the range of 98.8–99.7 % with Janthinobacterium lividum DSM 1522T, Janthinobacterium agaricidamnosum DSM 9628T and ‘Janthinobacterium svalbardensis JA-1', respectively. The calculated pairwise average nucleotide identity (ANI) values among the genomes of above seven strains were in the range of 79.0–92.2 %, except that the ANI value was 96.8 % between strain FT13WT and FT14W. The respiratory quinone of strains FT13WT, FT14W, FT58WT and FT68WT was determined to be Q-8. The major fatty acids were C16 : 1 ω7c, C16 : 0, C18 : 1 ω7c and C12 : 0. The polar lipids included phosphatidylethanolamine, phosphatidylglycerol and one unidentified phospholipid. The genome sizes of strains FT13WT, FT14W, FT58WT and FT68WT were 6.45, 6.38, 5.73 and 6.37 Mbp with G+C contents of 63.4, 63.7, 61.6 and 63.1 mol%, respectively. Combining phenotypic, biochemical, genotypic and ANI data, strain FT13WT and FT14W should belong to the same species. The four strains were considered to represent three novel species within genus Janthinobacterium , for which the names Janthinobacterium violaceinigrum sp. nov. (type strain FT13WT=GDMCC 1.1638T=KACC 21319T), Janthinobacterium aquaticum sp. nov. (FT58WT=GDMCC 1.1676T=KACC 21468T) and Janthinobacterium rivuli sp. nov. (FT68WT=GDMCC 1.1677T=KACC 21469T) are proposed.

Four strains (SYSU SYW-1T, SYW-2, SYW-3 and XLW-1) were isolated from seawater near the shore in Guangdong Province, China. Cells were Gram-stain-negative, aerobic, non-motile and non-spore-forming. Growth was observed at a temperature range of 16–40 °C (optimum, 32 °C), a pH range of 4–8 (optimum, pH 7) and in the presence of up to 10 % (w/v) NaCl. The major polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified phospholipid. The respiratory quinone was ubiquinone 8 (UQ-8), and the predominant fatty acids were C18 : 0 3-OH, C10 : 0, C14 : 0 and C18 : 1ω9c. Comparison of 16S rRNA gene and genome sequences confirmed that these strains represented a novel member of the genus Francisella , with less than 98.8 % 16S rRNA gene sequence similarity and less than 95 % genomic average nucleotide identity to recognized Francisella species. The phylogenetic tree based on 16S rRNA gene sequences and the protein-concatamer tree based on a concatenation of 28 protein marker sequences both indicated that the strains clustered with ‘Francisella salina’ TX07-7308 and ‘Francisella marina’ E95-16, but formed a distinct lineage group among the other members of the genus Francisella . The DNA G+C contents of the four strains were determined to be 32.9, 32.7, 32.9 and 32.9 %, respectively (genome). On the basis of phenotypic and genotypic features, the strains are considered to represent a novel species of the genus Francisella , for which the name Francisella salimarina sp. nov. is proposed. The type strain is SYSU SYW-1T (=CGMCC 1.17031T=NBRC 113781T).

Gravel Soil

A Gram-stain-negative, aerobic, non-motile, pink-pigmented, coccus bacterium, designated CPCC 101081T, was isolated from a gravel soil sample collected from Badain Jara desert, PR China. Growth of the isolate occurred at 10–37 °C and pH 5.0–8.0, with optimal growth at 28–32 °C and pH 7.0, respectively. The major cellular fatty acids were summed feature 8 (C18:1ω7c/C 18:1ω6c), summed feature 3 (C 16:1ω6c/C16:1ω7c) and C18:12-OH. Q-10 was detected as the main respiratory quinone. Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified phospholipid, an amino-containing lipid and an unidentified glycophospholipid were examined in the polar lipids extraction. The 16S rRNA gene sequence comparison of strain CPCC 101081T with the available sequences in the GenBank database showed that the isolate was closely related to members of the genus Rosenomonas, with the highest similarity to Roseomonas rosea DSM 14916T (97.4 %). In the phylogenetic trees based on 16S rRNA gene sequences and the core genomes, strain CPCC 101081T was included within the clade of the genus Roseomonas , representing a species level, with the closest neighbor of R. rosea DSM 14916T . The genomic DNA G+C content was 68.7 mol%. The average nucleotide identity and the digital DNA–DNA hybridization values between strain CPCC 101081T and the related type strains of the genus Roseomonas were all far lower than the cut-off values for definition species. On the basis of above phenotypic and genotypic characteristics, strain CPCC 101081T is proposed to represent a novel species of the genus Roseomonas with the name Roseomonas harenae sp. nov. strain CPCC 101081T (=KCTC 62852T=NBRC 113512T) is the type strain of the species.
