Exiguobacterium enclense sp. nov., isolated from sediment.

A Gram-stain-positive bacterium, designated strain NIO-1109T, was isolated from a marine sediment sample from Chorao Island, Goa, India. Phenotypic and chemotaxonomic characteristics and data from phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NIO-1109T was related to the genus Exiguobacterium . Strain NIO-1109T exhibited >98.0 % 16S rRNA gene sequence similarity with respect to Exiguobacterium indicum HHS 31T (99.5 %) and Exiguobacterium acetylicum NCIMB 9889T (99.1 %); the type strains of other species showed <98 % similarity. Levels of DNA–DNA relatedness between strain NIO-1109T and E. acetylicum DSM 20416T and E. indicum LMG 23471T were less than 70 % (33.0±2.0 and 37±3.2 %, respectively). Strain NIO-1109T also differed from these two closely related species in a number of phenotypic traits. Based on phenotypic, chemotaxonomic and phylogenetic data, strain NIO-1109T is considered to represent a novel species of the genus Exiguobacterium , for which the name Exiguobacterium enclense sp. nov. is proposed. The type strain is NIO-1109T ( = NCIM 5457T = DSM 25128T = CCTCC AB 2011124T).
