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

The taxonomic position of a marine actinomycete, strain SJS0289/JS1^T, was determined using a polyphasic taxonomic approach. The organism, which had phenotypic properties consistent with its classification in the genus Williamsia, formed a distinct clade in the 16S rRNA gene tree together with the type strain of Williamsia muralis, but was readily distinguished from this species using DNADNA relatedness and phenotypic data. The genotypic and phenotypic data show that the organism merits recognition as a new species of Williamsia. The name proposed for the new species is Williamsia maris; the type strain is SJS0289/JS1^T (=DSM 44693^T=JCM 12070^T=KCTC 9945^T=NCIMB 13945^T).
