A Gram-reaction-negative, strictly aerobic, non-motile bacterium, designated strain G4T, was isolated from a sandy beach of Taean in South Korea. Cells were ovoid rods and were catalase- and oxidase-positive. Growth of strain G4T was determined at 15–35 °C (optimum 25–30 °C) and pH 6–8 (optimum pH 6.5–7.5). Strain G4T contained Q-10 as the predominant isoprenoid quinone and C18 : 1ω7c (59.0 %), C18 : 1 ω7c 11-methyl (11.3 %) and C12 : 1 3-OH (9.8 %) as the major fatty acids. The major cellular polar lipids were identified as phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, an unidentified amino lipid, an unidentified phospholipid and an unidentified lipid. The DNA G+C content was 62.4 mol%. Phylogenetic and comparative analysis based on 16S rRNA gene sequences indicated that strain G4T fell within the family Rhodobacteraceae of Alphaproteobacteria and was most closely related to members of the genera Marinovum, Leisingera and Phaeobacter with 95.5–96.4 % sequence similarities. On the basis of phenotypic, chemotaxonomic and molecular properties, strain G4T represents a novel species of a novel genus within the family Rhodobacteraceae, for which the name Litorimicrobium taeanense gen. nov., sp. nov. is proposed.

A Gram-stain-negative, motile bacterium with two lateral flagella, designated strain B201T, was isolated from beach sand from the Taean coast in South Korea. Cells were ovoid rods and positive for catalase and oxidase. Growth of strain B201T was observed between 15 and 45 °C (optimum, 30 °C) and between pH 5.0 and 9.0 (optimum, pH 6.0–7.5). Strain B201T contained ubiquinone Q-8 as the major isoprenoid quinone, but MK-6 was also present as a minor quinone. The major fatty acids of strain B201T were C17 : 0 cyclo, C16 : 0, summed feature 2 (iso-C16 : 1 I/C14 : 0 3-OH and/or C12 : 0 ALDE), C12 : 0 and C19 : 0 cyclo ω8c. The major cellular polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and three aminolipids. The genomic DNA G+C content was 53.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain formed a phyletic lineage with Pusillimonas ginsengisoli DCY25T within the genus Pusillimonas. Strain B201T was most closely related to P. ginsengisoli DCY25T and Pusillimonas soli MJ07T with similarities of 98.6 and 97.5 %, respectively. However, DNA–DNA relatedness values of strain B201T with P. ginsengisoli DCY25T and P. soli MJ07T were 30.2±5.4 and 4.9±1.8 %, respectively. On the basis of chemotaxonomic data and molecular properties, strain B201T represents a novel species of the genus Pusillimonas, for which the name Pusillimonas harenae sp. nov. is proposed; the type strain is B201T ( = KACC 14927T = JCM 16917T).

Strain 15-4T, a Gram-stain-negative, rod-shaped, non-motile bacterial strain that produced flexirubin-type pigments, was isolated from Tibet Province, China, and characterized by using a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the family Chitinophagaceae, phylum ‘Bacteroidetes’, and was related to members of the genus Niabella, with sequence similarities ranging from 94.1 to 96.4 %. Strain 15-4T contained MK-7 as the predominant menaquinone and its DNA G+C content was 46.9 mol%. The major fatty acids of strain 15-4T were iso-C15 : 0 (41.3 %), iso-C15 : 1 G (14.9 %), iso-C17 : 0 3-OH (13.2 %) and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH, 16.0 %). These chemotaxonomic data supported the affiliation of strain 15-4T to the genus Niabella. However, a number of physiological and biochemical features enabled the isolate to be differentiated phenotypically from recognized species of the genus Niabella. On the basis of the evidence presented, it is proposed that strain 15-4T represents a novel species, Niabella tibetensis sp. nov.; the type strain is 15-4T ( = CCTCC AB 209167T = NRRL B-59394T). On the basis of these data, an emended description of the genus Niabella is also proposed.

A light-pink-coloured bacterium, designated strain 5416T-32T, was isolated from an air sample in Korea. Cells of the strain were strictly aerobic, Gram-negative, motile (single polar or subpolar flagellum) and rod-shaped. Optimal growth occurred at 25–30 °C and at pH 6.0–7.0. The major quinones were Q-10 and Q-8. The major fatty acids were C18 : 1 ω7c (53.8 %) and C16 : 0 (15.9 %). The G+C content of the genomic DNA was 65.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 5416T-32T was most closely related to Skermanella parooensis, with a similarity of 96.2 %, but relatively low sequence similarities (<92 %) were found with respect to other species with validly published names held in GenBank. Phenotypic and genotypic analyses indicated that strain 5416T-32T could not be assigned to any recognized species. Therefore strain 5416T-32T represents a novel species of the genus Skermanella, for which the name Skermanella aerolata sp. nov. is proposed. The type strain is 5416T-32T (=KACC 11604T=DSM 18479T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming, rod-shaped bacterial strain, designated THG 15T, was isolated from soil of a field cultivated with Rhus vernicifera in Okcheon province, South Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain THG 15T grew optimally at 25–30 °C and at pH 7 in the absence of NaCl on nutrient agar. Strain THG 15T displayed β-glucosidase (aesculinase) activity that was responsible for its ability to transform ginsenoside Rb1 (one of the dominant active components of ginseng) into compound K via Rd and F2. On the basis of 16S rRNA gene sequence similarities, strain THG 15T was shown to belong to the family Flavobacteriaceae and was most closely related to Chryseobacterium soldanellicola PSD1-4T (97.7 % sequence similarity), Chryseobacterium soli JS6-6T (97.5 %) and Chryseobacterium indoltheticum LMG 4025T (97.3 %). The G+C content of the genomic DNA was 35.7 mol%. The major menaquinone was MK-6 and the major fatty acids were iso-C15 : 0 (50.3 %), iso-C17 : 0 3-OH (21.9 %), summed feature 4 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH; 9.5 %) and iso-C17 : 1ω9c (9.3 %). DNA sequence analysis and chemotaxonomic data supported the affiliation of strain THG 15T to the genus Chryseobacterium. DNA–DNA relatedness values between strain THG 15T and its closest phylogenetic neighbours were <15 %. Strain THG 15T could be differentiated genotypically and phenotypically from recognized species of the genus Chryseobacterium. The isolate therefore represents a novel species, for which the name Chryseobacterium ginsenosidimutans sp. nov. is proposed. The type strain is THG 15T ( = KACC 14527T  = JCM 16719T).
