Abstract

A non-motile, yellow-pigmented bacterium, designated strain CW9, was isolated from a water-cooling system in Gwangyang, Republic of Korea. The cells were Gram-negative, catalase- and oxidase-positive, short rods. The major fatty acids were iso-C (45.5 %), iso-C 9 (14.4 %), iso-C 3-OH (13.0 %) and summed feature 3 (comprising iso-C 2-OH and/or C 7; 8.8 %). The DNA G+C content was 35.6 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain CW9 formed a lineage within the genus and was closely related to ATCC 35910 (98.4 % sequence similarity) and ATCC 29897 (97.8 % sequence similarity). Phenotypic characteristics and DNA–DNA relatedness data served to distinguish strain CW9 from these two species. On the basis of the evidence presented in this study, strain CW9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CW9 (=KCTC 12894=JCM 14756).
