Abstract

A yellow-pigmented, Gram-staining-negative, non-motile, strictly aerobic and rod-shaped bacterium, designated CS100, was isolated from soil in Chungbuk, Korea. Phylogenetic analysis and comparative studies based on the 16S rRNA gene sequence showed that strain CS100 belonged to the genus in the family . Strain CS100 showed the highest sequence similarities to JCM 13953 (97.6 %) and KACC 11410 (97.1 %). Sequence similarity to other members of the genus was 91.5–97.0 %. Growth occurred at 4–30 °C, at pH 5.0–9.0 and in the presence of 0–2 % (w/v) NaCl. Flexirubin-type pigments were produced. Menaquinone-6 (MK-6) was the major respiratory quinone and the major fatty acids were iso-C (17.3 %), summed feature 3 (comprising iso-C 2-OH and/or Cω7, 15.5 %) and C (11.8 %). The DNA G+C content was 36.4 mol%. Strain CS100 hydrolysed skimmed milk and gelatin, but not chitin or pectin, and showed oxidase and catalase activities. DNA–DNA relatedness was 3.0 % with JCM 13953 and 11.5 % with KACC 11410. On the basis of the evidence from this study, strain CS100 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CS100 ( = KACC 15048 = JCM 17386).
