Pseudoalteromonas byusanensis sp. nov., isolated from tidal flat sediment in Korea

Abstract

A Gram-negative, motile, strictly aerobic, violet-pigment-producing bacterium, designated strain FR1199(T), was isolated from tidal flat sediment of Byunsan, South Korea. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain FR1199(T) represents a distinct line of descent within the genus Pseudoafteromonas. The phenotypic features of strain FR1199(T) were similar to those of Pseudoalteromonas phenolica and Pseudoalteromonas luteoviolacea, but several physiological and chemotaxonomical properties readily distinguished strain FR1199(T) from these species. Major fatty acids were straight-chain saturated (C-16:0) and monounsaturated C(18:1)omega 7c fatty acids. The DNA G+C content was 39 mol%. On the basis of polyphasic evidence, it is concluded that the isolate represents a novel species within the genus Pseudoalteromonas, for which the name Pseudoalteromonas byunsanensis sp. nov. is proposed. The type strain is FR1199(T) (=JCM 12483(T)=KCTC 12274(T)).
