ABSTRACT
A Gram-stain-negative, strictly aerobic bacterium, designated strain PeD5T, was isolated from a green alga Pediastrum duplex from the Nakdong river of the Republic of Korea. Cells were non-motile cocci, catalase-negative and oxidase-positive. Growth of PeD5T was observed at 25-40 °C (optimum, 35 °C) and pH 5.0-10.0 (optimum, pH 7-8), and in the presence of 0-0.25% (w/v) NaCl (optimum, 0%). PeD5T contained C160, C181ω7c 11-methyl, summed feature 3 (comprising C161ω7c and/or C161ω6c) and summed feature 8 (comprising C181ω7c and/or C181ω6c) as major cellular fatty acids (>5%) and ubiquinone-10 as the sole isoprenoid quinone. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified phospholipid and an unidentified aminolipid were detected as major polar lipids. The genomic DNA G+C content of PeD5T was 71.0 mol%. PeD5T was most closely related to Roseomonas stagni HS-69T with a 97.6% 16S rRNA sequence similarity and shared less than 96.3% 16S rRNA sequence similarities with type strains of other species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that PeD5T formed a phyletic lineage with Roseomonas stagni HS-69T within the genus Roseomonas. On the basis of results of phenotypic, chemotaxonomic and molecular analysis, strain PeD5T clearly represents a novel species of the genus Roseomonas, for which the name Roseomonas algicola sp. nov. is proposed. The type strain is PeD5T (=KACC 19925T=JCM 33309T).
