Abstract

A Gram-negative, aerobic, saffron-coloured marine bacterium, designated HST1-43, was isolated from beach sediment on the coast in Jeju, Korea, and its taxonomic status was established in a polyphasic study. 16S rRNA gene sequence analyses revealed that the isolate belonged to the family . The closest phylogenetic neighbours of strain HST1-43 were members of the genera , and , with levels of sequence similarity in the range 96.3–96.5 %. The isolate was non-motile and required sea salts or natural seawater for growth. The optimum temperature and pH ranges for growth were 25–30 °C and pH 6.1–8.1, respectively. MK-6 was the major menaquinone. The dominant cellular fatty acids were iso-C, C, C, iso-C and iso-C 3-OH. The DNA G+C content was 36.2±0.4 mol%. On the basis of phylogenetic distance and phenotypic characteristics, the isolate is considered to represent a novel genus and species in the family , for which the name gen. nov., sp. nov. is proposed. The type strain is HST1-43 (=KCTC 12721=JCM 14021).
