Williamsia maris sp. nov., a novel actinomycete isolated from the Sea of Japan

Abstract

The taxonomic position of a marine actinomycete, strain SJS0289/JS1T, was determined using a polyphasic taxonomic approach. The organism, which had phenotypic properties consistent with its classification in the genusWilliamsia, formed a distinct clade in the 16S rRNA gene tree together with the type strain ofWilliamsia muralis, but was readily distinguished from this species using DNA–DNA relatedness and phenotypic data. The genotypic and phenotypic data show that the organism merits recognition as a new species ofWilliamsia. The name proposed for the new species isWilliamsia maris; the type strain is SJS0289/JS1T(=DSM 44693T=JCM 12070T=KCTC 9945T=NCIMB 13945T).
