A taxonomic study was carried out on a bacterial strain designated as Jip2T isolated from a soil sample mixed with rotten rice straw. It was a Gram-negative, aerobic, motile, and rod-shaped bacterium. It grew well on nutrient agar medium and utilized a fairly narrow spectrum of carbon source. The G+C content of the genomic DNA was 65.3 mol%. The major ubiquinone was Q-8. The major fatty acids were branched fatty acids, especially large amounts of iso C15:0 and iso C17:1 w9c were detected in the cells grown on TSA agar for 24 h. Comparative 16S rDNA study showed a clear affiliation of this bacterium to the genus Rhodanobacter. The 16S rDNA sequence of strain Jip2T showed 96.4% sequence similarity to that of Rhodanobacter lindaniclasticus RP5575T. On the basis of phenotypic characteristics and 16S rDNA sequence analysis, strain Jip2T is clearly distinct from Rhodanobacter lindaniclasticus. We propose the name Rhodanobacter fulvus sp. nov. for strain Jip2T (=IAM 15025T=KCTC 12098T).
