Abstract:
A Gram-stain-negative, strictly aerobic, catalase-negative, oxidase-positive and non-motile rod-shaped bacterium, designated strain CrO1 T , was isolated from a freshwater alga Cryptomonas obovoidea in the Nakdong river of South Korea. Colonies of CrO1 T were white, convex and circular and growth was observed at 25–40 °C (optimum, 37 °C) and pH 6.0–9.0 (optimum, pH 7) and in the presence of 0–0.5 % (w/v) NaCl (optimum, 0 %). CrO1 T contained C 16 : 0 , summed feature 5 (comprising C 18 : 0 ante and/or C 18 : 2 ω6,9 c ), C 18 : 0 , summed feature 3 (comprising C 16 : 1 ω7 c and/or C 16 : 1 ω6 c ) and summed feature 8 (comprising C 18 : 1 ω7 c and/or C 18 : 1 ω6 c ) as the major cellular fatty acids ( 〉 5 %) and ubiquinone-8 as the sole respiratory quinone. Phosphatidylethanolamine was detected as the major polar lipid. The DNA G+C content of CrO1 T , calculated from the whole genome sequence was 69.6 mol%. CrO1 T was most closely related to Ramlibacter humi 18x22-1 T with a 97.6 % 16S rRNA sequence similarity and shared less than 97.4 % 16S rRNA sequence similarities with other type strains. Phylogenetic analyses based on the 16S rRNA gene and whole genome sequences revealed that CrO1 T formed a distinct phyletic lineage within the genus Ramlibacter . On the basis of the results of phenotypic, chemotaxonomic and molecular analysis, CrO1 T clearly represents a novel species of the genus Ramlibacter , for which the name Ramlibacter algicola sp. nov. is proposed. The type strain is CrO1 T (=KACC 19926 T =JCM 33302 T ).
