Abstract

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, designated strain KIS83-12, was isolated from soil of Gaui island in the Taean region of South Korea. The strain grew at 15–33 °C (optimum, 28 °C), at pH 5.0–8.0 (optimum, pH 7.0). Growth did not occur in the presence of NaCl. The strain was catalase-negative and oxidase-positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that KIS83-12 was most closely related to DCY12 (96.9 %), MN28 (96.5 %), CW-KD 4 (96.5 %) and NAA16 (96.0 %), and formed a robust phyletic lineage with members of the genus . The main isoprenoid quinone was Q-8. Major polar lipids included phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Fatty acids present in large and moderate amounts (>5.0 %) were summed feature 8 (Cω7 and/or Cω6), C, Cω5, summed feature 2 (iso-C I and/or C 3-OH) and C. The DNA G+C content was 67.9 mol%. On the basis of the taxonomic data obtained in this study, KIS83-12 represents a novel species of the genus , for which the name sp. nov. is proposed, with KIS83-12 ( = KACC 16967 = DSM 27281) as the type strain.
