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.

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 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).

Two Gram-stain-negative, catalase- and oxidase-positive, rod-shaped, motile strains (FT29WT and FT103WT) were isolated from a subtropical stream in PR China. Comparisons based on 16S rRNA gene sequences showed that strains FT29WT and FT103WT showed 98.7 and 98.6 % 16S rRNA gene sequence similarities to Rugamonas rubra CCM 3730T as their closest neighbour, respectively. The calculated pairwise OrthoANIu values between strain R. rubra CCM 3730T and strains FT29WT and FT103WT were all 81.4 %. The respiratory quinone of strains FT29WT and FT103WT was determined to be Q-8. The major fatty acids were C16 : 1 ω7c, C16 : 0 and C12 : 0. The polar lipids of strain FT103WT included phosphatidylethanolamine, phosphatidylglycerol and one unidentified phospholipid, but strain FT29WT did not contain phosphatidylglycerol. The genome sizes of strains FT29WT and FT103WT were 7.23 and 6.84 Mbp with G+C contents of 63.8 and 63.9 %, respectively. Although the pairwise OrthoANIu value between strains FT29WT and FT103WT was 95.2 % which located in the transition region of species demarcation, the dissimilarities in the aspects of phenotypic, biochemical and genotypic characteristics supported these two strains should belong to the different species within genus Rugamonas , for which the names Rugamonas aquatica sp. nov. (type strain FT29WT=GDMCC 1.1643T=KACC 21316T) and Rugamonas rivuli sp. nov. (type strain FT103WT=GDMCC 1.1685T=KACC 21477T) are proposed.

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.

A novel salt-tolerant alpha-proteobacterium, designated SALINAS58T, was isolated from Santa Engracia hypersaline spring water in the Añana Salt Valley, Álava, Spain. The isolate was Gram-negative, aerobic, non-motile, catalase-positive, oxidase-negative, rod-shaped and formed orange colonies on marine agar. Optimal growth was observed at pH 6.0–6.5, at 30 °C and in the presence of 1% (w/v) NaCl. The main cellular fatty acids (>20%) were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c) and summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c). The major respiratory quinone was ubiquinone Q-10 and the major polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidilglycerol, four unidentified glycolipids and one unidentified phospholipid. Strain SALINAS58T had the highest 16S rRNA gene sequence similarity to Altererythrobacter marensis MSW-14T (96.6%), Altererythrobacter aquaemixtae JSSK-8T (96.5%) and Pontixanthobacter luteolus SW-109T (96.5%) followed by Altererythrobacter atlanticus 26DY36T (96.4%). Results of the phylogenetic analysis, based on 16S rRNA gene sequences, and phylogenetic approaches based on whole genome nucleotide differences, showed that strain SALINAS58T could be distinguished from recognized species of the genus Altererythrobacter . The genomic DNA G+C content was 61.4 mol%. Digital DNA–DNA hybridization, average nucleotide identity and average aminoacid identity values between the genome of strain SALINAS58T and A. marensis MSW-14T were 18.4, 73.1 and 68.1%, respectively. Based on data from this polyphasic characterization, strain SALINAS58T (=CECT 30029T=LMG 31726T) is considered to be classified as representing a novel species in the genus Altererythrobacter , for which the name Altererythrobacter muriae sp. nov. is proposed.

A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0–28 °C, pH 6.0–8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family Sphingosinicellaceae but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to Polymorphobacter arshaanensis DJ1R-1T (95.24 %), Sphingoaurantiacus capsulatus YLT33T (94.78 %) and Sandarakinorhabdus limnophila DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of Polymorphobacter arshaanensis , Sphingoaurantiacus capsulatus and Sandarakinorhabdus limnophila . Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family Sphingosinicellaceae is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).

Two Gram-stain-negative, yellow-pigmented and strictly aerobic bacteria, designated strains SE-s27T and SE-s28T, were isolated from forest soil. Both strains were non-motile rods that were catalase-positive and oxidase-negative and grew optimally at 25–30 °C, pH 8.0 and with 0 % (w/v) NaCl. Strain SE-s28T produced flexirubin-type pigments, but strain SE-s27T did not produce them. Both strains contained menaquinone-6 as the sole respiratory quinone and phosphatidylethanolamine as a major polar lipid. As the major cellular fatty acids (>10 %), SE-s27T contained iso-C15 : 1 and iso-C15 : 1G, whereas SE-s28T contained iso-C15 : 0 and summed feature 3 comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH. The DNA G+C contents of strains SE-s27T and SE-s28T were 33.1 and 44.3 mol%, respectively. The results of phylogenetic analysis based on 16S rRNA gene sequences revealed that SE-s27T and SE-s28T formed respective distinct phylogenetic lineages within the genus Flavobacterium . Strains SE-s27T and SE-s28T were most closely related to Flavobacterium macrobrachii an-8T and Flavobacterium piscinae ICH-30T with 98.0 and 94.5 % 16S rRNA gene sequence similarities, respectively. In conclusion, strains SE-s27T and SE-s28T represent novel species of the genus Flavobacterium , for which the names Flavobacterium solisilvae sp. nov. and Flavobacterium silvaticum sp. nov. are proposed. The type strains of F. solisilvae and F. silvaticum are SE-s27T (=KACC 18802T=JCM 31544T) and SE-s28T (=KACC 18803T=JCM 31545T), respectively.

Harbour Seals

A polyphasic taxonomic study was performed on two previously unidentified Arcanobacterium -like Gram-positive strains isolated from harbour seals. Comparative 16S rRNA gene sequencing showed that both bacteria belonged to the genus Arcanobacterium and were most closely related to Arcanobacterium haemolyticum CIP 103370T (98.4 % 16S rRNA gene sequence similarity), A. canis P6775T (97.4 %), A. phocae DSM 10002T (97.4 %), A. pluranimalium M430/94/2T (95.7 %) and A. hippocoleae CCUG 44697T (95.5 %). The presence of the major menaquinone MK-9(H4) supported the affiliation of the isolates with the genus Arcanobacterium . The polar lipid profile consisted of major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, an unidentified phospholipid and two unidentified glycolipids. The major fatty acids were C16 : 0, C18 : 0, C18 : 1ω9c and summed feature 5 (comprising C18 : 2ω6,9c and/or anteiso-C18 : 0). Physiological and biochemical tests clearly distinguished the isolates from other members of the genus Arcanobacterium . Based on the common origin and various physiological properties comparable to those of A. phocae , it is proposed that the isolates are classified as members of a novel species with the name Arcanobacterium phocisimile sp. nov. The type strain is 2698T ( = LMG 27073T  = CCM 8430T).
