Abstract

A Gram-positive, spore-forming, rod-shaped halophilic bacterial strain, IGA7-4, was isolated from a mangrove area on Ishigaki Island (Japan), and was characterized taxonomically using a polyphasic approach. Strain IGA7-4 was strictly aerobic and non-motile and formed central endospores. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain IGA7-4 is affiliated to the genus , and exhibits sequence similarities of 99.6–98.0 % to the type strains of species. Levels of DNA–DNA relatedness between strain IGA7-4 and the type strains of species were 9.5–46.6 %. The DNA G+C content of strain IGA7-4 was 46.5 mol%. The cell-wall peptidoglycan type (Orn–Asp), major cellular fatty acids (anteiso-C, anteiso-C, iso-C and iso-C) and quinone type (MK-7) of the isolate support its affiliation to the genus . On the basis of phylogenetic analysis, phenotypic characteristics and chemotaxonomic data, the isolate represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is IGA7-4 (=MBIC08268=IAM 15427=KCTC 13121).
