A Gram-stain-negative, short rod-shaped, non-motile, non-spore-forming bacterial strain, designated H7T, was isolated from the Gobi desert, Xinjiang Province of China. The temperature, NaCl and pH ranges for growth were 8–40 °C (optimum 30 °C), 0–5 % (w/v) NaCl and pH 6–10 (optimum pH 7), respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain H7T belonged to the genus Sphingobacterium and showed highest sequence similarity (91 %) to Sphingobacterium composti DSM 18850. The genomic DNA G+C content was 44.3 mol%. MK-7 was identified as the predominant respiratory quinone. Strain H7T contained C16 : 1ω7c and/or C16 : 1ω6c, iso-C15 : 0 and iso-C17 : 0 3-OH as major fatty acids. These data support the affiliation of strain H7T to the genus Sphingobacterium while phenotypic data indicated it is a representative strain of a novel species for which the name Sphingobacterium gobiense sp. nov. is proposed. The type strain is H7T ( = ACCC 05757T = KCTC 32293T).

A Gram-negative bacterium, designated DCY13T, was isolated from soil of a ginseng field in South Korea. Comparative analysis of 16S rRNA gene sequences showed that strain DCY13T shared the highest sequence similarity (95.0 %) with Sediminibacterium salmoneum NBRC 103935T and 87.6–91.4 % sequence similarity with other members of the family Chitinophagaceae . Cells were non-spore-forming rods, catalase- and oxidase-positive, motile by gliding and facultatively anaerobic. The only respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0 and iso-C15 : 1 G. The G+C content of the genomic DNA was 47.5±1.0 mol%. In addition to phosphatidylethanolamine, the major polar lipids were two unidentified aminophospholipids, one unidentified aminolipid and three unidentified polar lipids. The major cell-wall sugars were ribose, xylose and galactose. It is proposed that strain DCY13T represents a novel species in the genus Sediminibacterium , for which the name Sediminibacterium ginsengisoli sp. nov. is proposed. The type strain is DCY13T ( = KCTC 12833T  = JCM 15794T  = DSM 22335T). Emended descriptions of the genus Sediminibacterium and of Sediminibacterium salmoneum are also proposed.

A Gram-stain-negative, aerobic, orange-pigmented, rod-shaped and non-motile bacterium, designated strain A6B8T, was isolated from seawater of the Mariana Trench. The isolate grew at 4–50 °C (optimum 30–35 °C), at pH 6.5–8.0 (optimum pH 7.5) and with 0.5–4.0 % (w/v) NaCl (optimum 1.0–2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain A6B8T was related most closely to the genus Muriicola and shared highest sequence similarity of 97.7 % with Muriicola jejuensis EM44T. Chemotaxonomic analysis showed menaquinone 6 (MK-6) was the predominant isoprenoid and iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH were the major cellular fatty acids. The polar lipid profile of strain A6B8T included phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids. The genomic DNA G+C content was 47.1 mol%. The DNA–DNA relatedness value (23.3 %) clearly demonstrated that strains A6B8T and M. jejuensis EM44T were representatives of two different species. Based on the phenotypic, phylogenetic and chemotaxonomic characterizations, A6B8T ( = CGMCC 1.12606T = KCTC 32436T) is considered to be the type strain of a novel species of the genus Muriicola , for which the name Muriicola marianensis sp. nov. is proposed.

Polyphasic Characterization

Strain M2T, isolated from marine sediment collected at Jeju Island, was an aerobic, Gram-stain-negative, oxidase- and catalase-positive, motile, rod-shaped bacterium that formed circular, raised, yellow colonies. Strain M2T grew at 15–42 °C, pH 5.5–9.0 and with 1–9 % (w/v) NaCl. Phylogenetic analysis based on its 16S rRNA gene sequences indicated that strain M2T was closely related to Kineobactrum sediminis F02T (98.0 % sequence similarity). Ubiquinone-8 was determined to be the sole respiratory quinone. Summed feature 3 (C16 : 1  ω6c/C16 : 1  ω7c) and summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c) were identified as the predominant fatty acids. The DNA G+C content and digital DNA–DNA relatedness between strain M2T and K. sediminis F02T were 60.7 mol% and 19.5 %, respectively. Phosphatidylglycerol and phosphatidylethanolamine were identified as the major polar lipids. Thus, polyphasic characterization revealed that strain M2T represents a novel species in the genus Kineobactrum , for which the name Kineobactrum salinum sp. nov. is proposed. The type strain is M2T (=KCTC 72815T=VTCC 910108T).

Comparative genome analysis between strain KIS59-12T and A. rhizosphaerae Vu-144T showed that average nucleotide identity value was 69.4 % and the digital DNA–DNA hybridization value was 19.1 %. The major respiratory quinone was menaquinone-7. The major polar lipids were phosphatidylethanolamine and an unknown polar lipid. The predominant cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH, which supported the affiliation of strain KIS59-12T with the genus Arachidicoccus . The major polyamines were homospermidine and putrescine. The genomic DNA G+C content was 36.4 mol%. On the basis of phylogenetic, physiological and chemotaxonomic characteristics, strain KIS59-12T represents a novel species of the genus Arachidicoccus , for which the name Arachidicoccus soli sp. nov. is proposed. The type strain of Arachidicoccus soli is KIS59-12T (=KACC 17340T=NBRC 113161T).

A Gram-staining-negative, non-spore-forming, non-gliding and rod-shaped bacterial strain KYW566T, was isolated from seawater of the Suncheon Bay, Korea, and its taxonomic position was investigated by using a polyphasic study. The cells contained MK-6 as the only respiratory quinone and contained iso-C15 : 0 (13.8 %), iso-C16 : 0 3-OH (13.1 %), anteiso-C15 : 0 (9.3 %), iso-C15 : 0 3-OH (8.7 %), iso-C15 : 1 G (6.3 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) (6.0 %) as the major fatty acids. The DNA G+C content of strain KYW566T was 41.6±0.8 mol% (mean±sd of three determinations). A phylogenetic tree based on 16S rRNA gene sequences showed that strain KYW566T forms an evolutionary lineage within the radiation enclosing the members of the genus Lutibacter with Lutibacter flavus IMCC1507T as its nearest neighbour (96.7 % sequence similarity). A number of phenotypic characteristics distinguished strain KYW566T from described members of the genus Lutibacter . On the basis of the evidences presented in this study, strain KYW566T represents a novel species, for which the name Lutibacter agarilyticus sp. nov. is proposed. The type strain is KYW566T ( = KCTC 23842T = JCM 18281T).

A Gram-stain-negative, rod-shaped and non-endospore-forming bacterium, designated strain AG1-2T, was isolated from Takakia lepidozioides collected from the Gawalong glacier in Tibet, China and characterized using a polyphasic taxonomic approach. The predominant fatty acids of strain AG1-2T were iso-C15 : 0 (36.0 %), iso-C17 : 0 3-OH (20.2 %), summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl, 16.4 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 11.1 %). The major polar lipids were phosphatidylethanolamine, three unidentified aminolipids and two unidentified lipids. Strain AG1-2T contained MK-6 as the dominant menaquinone, and the genomic DNA G+C content was 37.3 mol%. The phylogenetic analysis based on the 16S rRNA gene sequences showed that strain AG1-2T was affiliated to species of the genus Chryseobacterium , and its closest related species were Chryseobacterium taiwanense Soil-3-27T, Chryseobacterium hispalense AG13T, Chryseobacterium camelliae THG C4-1T and Chryseobacterium taeanense PHA3-4T with a sequence similarity of 98.0, 97.8, 97.3 and 97.1 %, respectively. However, the DNA–DNA relatedness values between these strains and strain AG1-2T were 29, 21, 21 and 45 %, respectively. Based on phylogenetic inference and phenotypic data, strain AG1-2T is considered to represent a novel species of the genus Chryseobacterium , for which the name Chryseobacterium takakiae sp. nov. is proposed.
