sp. nov., a biosurfactant-producing actinobacterium isolated from marine sediment.

A novel actinobacterium producing biosurfactant, designated OTB305, was isolated from marine sediment sampled at Otsuchi Bay, Iwate Prefecture, Japan and its taxonomic position was examined using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences exhibited that strain OTB305 was closely related to JCM 19630 (98.8 %) and DSM 42084 (98.
