Abstract

A novel marine bacterium was isolated from a sediment sample from Hwasun Beach in Jeju, Republic of Korea. The cells were found to be Gram-negative, aerobic, oxidase-positive, catalase-positive, motile rods. The organism required natural seawater or artificial sea salts for growth. The temperature and pH ranges for growth were 20–42 °C and pH 5.1–12.1, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the order and formed a robust cluster with members of the genus . Its phylogenetic neighbours were the type strains of (96.8 % 16S rRNA gene sequence similarity), (96.7 %), (96.5 %) and (96.2 %), ‘’ DCY11 (96.2 %) and ‘ Devosia euplotis’ (96.2 %). The predominant ubiquinone was Q-10, the major fatty acids were C, C and C and the G+C content of the DNA was 59.1 mol%. On the basis of phenotypic data and the results of phylogenetic analyses, strain HST3-14 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is strain HST3-14 (=KCTC 12772 =JCM 14206).
