During diversity studies of the glacier forefields of the Larsemann Hills, East Antarctica, a novel psychrotolerant, non-motile Gram-negative, shiny yellow, rod-shaped, aerobic bacterium, designated strain PB4T was isolated from a soil sample. Strain PB4T produces indole from tryptophan and hydrolyses casein. It grows between 0 and 25 °C with an optimum growth temperature of 20 °C. A wide range of substrates are used as sole carbon sources and acid is produced from numerous carbohydrates. The major menaquinone is MK-6. Identified polar lipids are ethanolamines and ornithine lipids. Major fatty acids (>10 %) are iso-C15 : 0 (13.0 %) and iso-2OH-C15 : 0 (51.2 %). G+C content is 33.7 mol%. The polyamine pattern is composed of sym-homospermidine (25.1 µmol g−1 dry weight), minor amounts of cadaverine (0.2 µmol g−1 dry weight) and spermidine (0.4 µmol g−1 dry weight) and traces of putrescine and spermine (<0.1 µmol g−1 dry weight). Strain PB4T had highest 16S rRNA gene similarities with the type strains of Chryseobacterium humi (97.0 %) and Chryseobacterium marinum (96.5 %). Considering phenotypic and genotypic characterization, strain PB4T represents a novel species in the genus Chryseobacterium (family Flavobacteriaceae ), for which the name Chryseobacterium frigidisoli sp. nov. is proposed. The type strain is PB4T ( = DSM 26000T = LMG 27025T).

A novel psychrotolerant, Gram-negative, shiny white, curved-rod-shaped, facultatively anaerobic bacterium PB1T was isolated from a soil sample collected from a glacier forefield of the Larsemann Hills, East Antarctica. Isolate PB1T has catalase and low urease activity and hydrolyses gelatin and starch. Strain PB1T is able to grow between −5 °C and 30 °C with optimum growth at 14–20 °C. Glycerol, dl-arabinose, d-xylose, d-galactose, d-fructose, d-lyxose, d-fucose and potassium gluconate are used as sole carbon sources. The major quinone is ubiquinone Q-8. The major fatty acids (>10 %) for PB1T are C16 : 0 (19.1 %), C16 : 1ω7cis (44.6 %) and C18 : 1ω7cis (16.2 %). The major polyamines are putrescine [54.9 µmol (g dry weight)−1] and 2-hydroxy putrescine [18.5 µmol (g dry weight)−1]. DNA G+C content is 62.5 mol%. Strain PB1T is phylogenetically related to species of the genus Herbaspirillum , with highest 16S rRNA gene sequence similarities to Herbaspirillum canariense (97.3 %), Herbaspirillum aurantiacum (97.2 %), Herbaspirillum soli (97.2 %) and Herbaspirillum frisingense (97.0 %). The DNA–DNA relatedness values were below 30 % between PB1T and the type strains of Herbaspirillum canariense , Herbaspirillum aurantiacum and Herbaspirillum soli . The different geographical origin of strain PB1T from its closest phylogenetic relatives resulted in different phenotypic and genotypic specifications, whereby strain PBT represents a novel species of the genus Herbaspirillum , for which the name Herbaspirillum psychrotolerans is proposed. The type strain is PB1T (DSM 26001T = LMG 27282T).

Members of the metabolically diverse order Nitrosomonadales inhabit a wide range of environments. Two strains affiliated with this order were isolated from soils in Germany and characterized by a polyphasic approach. Cells of strains 0125_3T and Swamp67T are Gram-negative rods, non-motile, non-spore-forming, non-capsulated and divide by binary fission. They tested catalase-negative, but positive for cytochrome c-oxidase. Both strains form small white colonies on agar plates and grow aerobically and chemoorganotrophically on SSE/HD 1 : 10 medium, preferably utilizing organic acids and proteinaceous substrates. Strains 0125_3T and Swamp67T are mesophilic and grow optimally without NaCl addition at slightly alkaline conditions. Major fatty acids are C16 : 1  ω7c, C16 : 0 and C14 : 0. The major polar lipids are diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyglycerol. The predominant respiratory quinone is Q-8. The G+C content for 0125_3T and Swamp67T was 67 and 66.1 %, respectively. The 16S rRNA gene analysis indicated that the closest relatives (<91 % sequence similarity) of strain 0125_3T were Nitrosospira multiformis ATCC 25196T, Methyloversatilis universalis FAM5T and Denitratisoma oestradiolicum AcBE2-1T, while Nitrosospira multiformis ATCC 25196T, Nitrosospira tenuis Nv1T and Nitrosospira lacus APG3T were closest to strain Swamp67T. The two novel strains shared 97.4 % 16S rRNA gene sequence similarity with one another and show low average nucleotide identity of their genomes (83.8 %). Based on the phenotypic, chemotaxonomic, genomic and phylogenetic analysis, we propose the two novel species Usitatibacter rugosus sp. nov (type strain 0125_3T=DSM 104443T=LMG 29998T=CECT 9241T) and Usitatibacter palustris sp. nov. (type strain Swamp67T=DSM 104440T=LMG 29997T=CECT 9242T) of the novel genus Usitatibacter gen. nov., within the novel family Usitatibacteraceae fam. nov.

A rod-shaped, yellow-pigmented, Gram-stain-negative, non-motile and aerobic bacterium, designated 7-3AT, was isolated from soil from King George Island, maritime Antarctica, and subjected to a polyphasic taxonomic study. Growth occurred at 4–37 °C (optimum, 20°C) and at pH 5.0–9.0 (optimum, pH 7.0–8.0). Tolerance to NaCl was up to 4 % (w/v) with optimum growth in the absence of NaCl. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 7-3AT represented a member of the family Flavobacteriaceae . Strain 7-3AT showed the highest sequence similarities with Kaistella yonginensis HMD 1043T (96.65 %), Kaistella carnis NCTC 13525T (96.53 %), Kaistella chaponensis DSM 23145T (96.27 %), Kaistella antarctica LMG 24720T (96.13 %) and Kaistella jeonii DSM 17048T (96.06 %). A whole genome-level comparison of 7-3AT with K. jeonii DSM 17048T, K. antarctica LMG 24720T, K. chaponensis DSM 23145T, and Kaistella palustris DSM 21579T revealed average nucleotide identity (ANI) values of 79.03, 82.25, 78.12, and 74.42 %, respectively. The major respiratory isoprenoid quinone was identified as MK-6 and a few ubiquinones Q-10 were identified. In addition, flexirubin-type pigments were absent. The polar lipid profile of 7-3AT was found to contain one phosphatidylethanolamine, six unidentified aminolipids (AL) and two unidentified lipids (L). The G+C content of the genomic DNA was determined to be 34.54 mol%. The main fatty acids were iso-C15 : 0, summed feature 9 (comprising iso-C17 : 1ω9c and/or C16 : 0 10-methyl), anteiso-C15 : 0, iso-C13 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). On the basis of the evidence presented in this study, a novel species of the genus Kaistella , Kaistella flava sp. nov., is proposed, with the type strain 7-3AT (=CCTCC AB 2016141T= KCTC 52492T). Emended descriptions of Kaistella yonginensis , Kaistella jeonii , Kaistella antarctica and Kaistella chaponensis are also given.

A Gram-stain-negative, non-motile and aerobic bacterium, designated CF17T, was isolated from coastal planktonic seaweeds, East China Sea. The isolate grew at 18–37 °C (optimum 25–28 °C), pH 6.5–9.0 (optimum 7.0–8.0) and with 0–5 % NaCl (optimum 1–2 %, w/v) and 0.5–10 % sea salts (optimum 2–3 %, w/v). Growth of strain CF17T could be stimulated prominently by supplementing the growth medium with the autoclaved supernatant of a culture of strain CF5, which was isolated from the same sample along with strain CF17T. The cell morphology of strain CF17T was a bean-shaped rod consisting of a swollen end and a long prostheca. The phylogenetic analysis of 16S rRNA gene sequences indicated that strain CF17T clustered with Gemmobacter nectariphilus DSM 15620T within the genus Gemmobacter . The DNA G+C content of strain CF17T was 61.4 mol%. The respiratory quinone was ubiquinone Q-10. The major fatty acids included C18 : 1ω7c and C18 : 0. The polar lipids of strain CF17T consisted of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, two uncharacterized phospholipids, one uncharacterized aminolipid, three uncharacterized glycolipids and one uncharacterized lipid. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain CF17T ( = CGMCC 1.11024T = JCM 18498T) is considered to represent a novel species of the genus Gemmobacter , for which the name Gemmobacter megaterium sp. nov. is proposed.

A Gram-staining-negative, facultatively aerobic bacterium, designated SM-2T, was isolated from a sea-tidal flat of Yellow Sea, South Korea. Cells were catalase- and oxidase-positive motile rods with a single polar flagellum. Growth of strain SM-2T was observed at 10–37 °C (optimum, 25–30 °C), at pH 5.5–8.5 (optimum, pH 7.0–7.5) and in the presence of 0–11 % (w/v) NaCl (optimum, 2 %). Strain SM-2T contained ubiquinone-8 (Q-8) as the sole isoprenoid quinone and C17 : 1ω8c, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C17 : 0 and C18 : 1ω7c as the major fatty acids. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified lipid were identified as the major cellular polar lipids. The G+C content of the genomic DNA was 52.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SM-2T formed a tight phyletic lineage with Zhongshania antarctica ZS5-23T, Zhongshania guokunii ZS6-22T and Spongiibacter borealis CL-AS9T, but that S. borealis CL-AS9T was distinct from other species of the genus Spongiibacter . Based on 16S rRNA gene sequence similarities, strain SM-2T was most closely related to S. borealis CL-AS9T, Z. antarctica ZS5-23T and Z. guokunii ZS6-22T, with similarities of 99.5 %, 98.9 % and 98.7 %, respectively, but the DNA–DNA hybridization values among these species were clearly lower than 70 %. On the basis of chemotaxonomic data and molecular properties, we propose strain SM-2T represents a novel species of the genus Zhongshania with the name Zhongshania aliphaticivorans sp. nov. (type strain SM-2T = KACC 18120T = JCM 30138T). We also propose the transfer of Spongiibacter borealis Jang et al. 2011 to the genus Zhongshania as Zhongshania borealis comb. nov. (type strain CL-AS9T = KCCM 90094T = JCM 17304T).

Strain BA42AL-1T grew in media containing 5–20 % (w/v) salts (optimum 7.5 % salts). It grew between pH 6.0 and 9.0 (optimally at pH 7.5) and at 15–45 °C (optimally at 37 °C). Phylogenetic analysis based on the comparison of 16S rRNA gene sequences revealed that strain BA42AL-1T is a member of the genus Aquisalimonas . The closest relatives to this strain were Aquisalimonas halophila YIM 95345T and Aquisalimonas asiatica CG12T with sequence similarities of 99.4 % and 97.0 %, respectively. DNA–DNA hybridization between the novel isolate and Aquisalimonas halophila YIM 95345T revealed a relatedness of 54 %. The major fatty acids of strain BA42AL-1T were C18 : 1ω6c/C18 : 1ω7c, C19 : 0 cyclo ω8c and C16 : 0, and lower contents of C12 : 0 and C18 : 0. The polar lipid pattern of strain BA42AL-1T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylcholine, two glycolipids, a lipid and four unknown phospholipids. The G+C content of the genomic DNA of this strain was 65.0 mol%. Based on the DNA–DNA hybridization, phenotypic, chemotaxonomic and phylogenetic data presented in this study, strain BA42AL-1T is proposed as a novel species of the genus Aquisalimonas , for which the name Aquisalimonas lutea sp. nov. is suggested. The type strain is BA42AL-1T ( = CCM 8472T = CECT 8326T = LMG 27614T).

16S rRNA gene sequences deposited for the type strains of Paraoerskovia marina (CTT-37T; GenBank accession no. AB445007) and Koreibacter algae (DSW-2T; FM995611) show a similarity of 100 %. Consequently, the type strains were subjected to a polyphasic recharacterization under direct comparison in order to clarify their taxonomic position. PvuII RiboPrint patterns and quantitative ratios of cellular fatty acids revealed strain-specific differences between P. marina DSM 21750T ( = CTT-37T) and K. algae DSM 22126T ( = DSW-2T). The percentage of DNA–DNA binding of 94 % indicated that the two type strains belong to the same genomospecies. Agreement in the peptidoglycan structure and polar lipid pattern, highly similar fatty acid profiles and MALDI-TOF mass spectra, the ability to produce acid from the same carbon sources, corresponding enzymic activities and DNA G+C contents of 70.8±0.3 mol%, in addition to the consistent characteristics reported in the original descriptions, support the view that the two strains should be affiliated to the same species. According to Rules 38 and 42 of the Bacteriological Code, Koreibacter algae should be reclassified as later heterotypic synonym of Paraoerskovia marina , and the descriptions of the genus Paraoerskovia Khan et al. 2009 and of Paraoerskovia marina Khan et al. 2009 are emended accordingly.
