<Emphasis Type="Italic">Flavobacterium koreense</Emphasis> sp. nov., <Emphasis Type="Italic">Flavobacterium chungnamense</Emphasis> sp. nov., and <Emphasis Type="Italic">Flavobacterium cheonanense</Emphasis> sp. nov., isolated from a freshwater reservoir

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium.

A Gram-positive and endospore-forming bacterial strain, designated S4^T, was isolated from the rhizosphere of ferns in Daejeon, Republic of Korea. This isolate is strictly aerobic, motile, and rod-like in shape, and it is positive for catalase, oxidase, esterase lipase, and β-galactosidase activities. In addition, this strain grows when cultured at temperatures between 15 and 37°C and at pH values ranging from 5.5 to 9.0. The DNA G+C content was determined to be 53.2 mol%. Strain S4^T has meso-diaminopimelic acid in the cell-wall peptidoglycan; it also contains menaquinone 7 (MK-7) as the predominant isoprenoid quinone and anteiso-C_15:0 (57.5%), iso-C_16:0 (11.3%), and C_16:0 (9.4%) as the major cellular fatty acids.

Kretzschmaria varians, a species apparently related to K. micropus, is described as new.

<Emphasis Type="Italic">Spirosoma lituiforme</Emphasis> sp. nov., isolated from soil

A Gram-staining-negative, non-motile, curved rod-shaped, aerobic bacterium, designated S1-2-4^T, was isolated from soil in Jeollabuk-do province, Republic of Korea, and was characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain S1-2-4^T was a member of the family Cytophagaceae and most closely related to ‘Spirosoma radiotolerans’ DG5A (97.2%), Spirosoma fluviale MSd3^T (96.4%), and Spirosoma linguale DSM 74^T (96.3%). The genomic DNA G + C content of strain S1-2-4^T was 49.7 mol%. The major fatty acids were summed feature 3 (C_16:1ω7c/C_16:1ω6c), C_16:1ω5c, and C_16:0, and the major polar lipid was phosphatidylethanolamine. MK-7 was the predominant respiratory quinone. Phenotypic and chemotaxonomic data supported the affiliation of strain S1-2-4^T with the genus Spirosoma. DNA-DNA hybridization between strain S1-2-4^T and ‘Spirosoma radiotolerans’ showed relatively low DNA-DNA relatedness (31%). Strain S1-2-4^T could be distinguished from its closest phylogenetic neighbors based on its phenotypic, genotypic, and chemotaxonomic features. Therefore, strain S1-2-4^T represents a novel member of the genus Spirosoma, for which the name Spirosoma lituiforme sp. nov. is proposed. The type strain is S1-2-4^T (= KCTC 52724^T = JCM 32128^T).     

<Emphasis Type="Italic">Viridibacterium curvum</Emphasis> gen. nov., sp. nov., isolated from freshwater

A Gram stain-negative, yellowish green-pigmented, facultatively anaerobic, motile, curved rod-shaped bacterium designated as strain JJ016^T was isolated from an artificial lake in South Korea, and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain JJ016^T indicated that the isolate belonged to the family Rhodocyclaceae and exhibited 95.0% identity to Uliginosibacterium gangwonense 5YN10-9^T. The major cellular fatty acids of the novel strain were summed feature 3 (C_16:1 ω6c and/or C_16:1 ω7c), C_16:0, C_14:0, and summed feature 8 (C_18:1 ω7c and/or C_18:1 ω6c). The DNA G+C content of strain JJ016^T was 61.9 mol%. The major respiratory quinone and major polar lipid of strain JJ016^T were ubiquinone-8 and phosphatidylethanolamine, respectively. Based on the morphological and physiological properties and the biochemical evidence presented, we concluded that strain JJ016^T represents a novel species of a new genus in the family Rhodocyclaceae, for which the name Viridibacterium curvum gen. nov., sp. nov. is proposed. The type strain is JJ016^T (=KACC 16899^T =JCM 18715^T).     

<Emphasis Type="Italic">Acidovorax monticola</Emphasis> sp. nov., isolated from soil

A novel strain K-4-16^T was isolated from forest soil of Namsan Mountain, Seoul, South Korea, and was taxonomically characterized by a polyphasic approach. Strain K-4-16^T was observed to be a Gram-staining negative, grayish white-coloured, motile with peritrichous flagella, and rod shaped bacterium. It was able to grow at 15–45 °C, at pH 4.5–10.5, and at 0–4% (w/v) NaCl concentration. Based on the 16S rRNA gene sequence analysis, strain K-4-16^T belongs to the genus Acidovorax and is closely related to Acidovorax anthurii CFBP 3232^T (98.3% sequence identity), Acidovorax konjaci K2^T (97.9% sequence identity), Acidovorax valerianellae CFBP 4730^T (97.8% sequence identity), and Acidovorax caeni R-24608^T (97.8% sequence identity). The only respiratory quinone was ubiquinone-8. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. The predominant fatty acids of strain K-4-16^T were summed feature 3 (C_16:1ω7c and/or C_16:1ω6c), C_16:0, and summed feature 8 (C_18:1ω7c and/or C_18:1ω6c). The genomic DNA G+C content of this novel strain was 64.7 mol%. The DNA–DNA relatedness between strain K-4-16^T and its reference strains were below the threshold value of 70%. The morphological, physiological, chemotaxonomic, and phylogenetic analyses clearly distinguished this strain from its close phylogenetic neighbors. Thus, strain K-4-16^T represents a novel species of the genus Acidovorax, for which the name Acidovorax monticola sp. nov. is proposed. The type strain is K-4-16^T (=?KEMB 9005-570^T?=?KACC 19171^T?=?NBRC 113141^T).
