Abstract

A xylanolytic bacterium, US15, was isolated from swamp forest soil in Ulsan, Korea. The cells of the novel strain were Gram-positive, non-motile, short-rod-shaped and showed chemotaxonomic properties that were consistent with its classification in the genus . Chemotaxonomic results showed MK-12 and MK-11 as major menaquinones, predominating iso- and anteiso-branched cellular fatty acids, glucose, galactose and mannose as cell-wall sugars, peptidoglycan-type B2 with glycolyl residues and a DNA G+C content of 66·5 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain US15 was closely related to IFO 3750, IFO 12610 and LMG 20991 (96·9, 96·8 and 96·2 % similarities, respectively), and formed a separate lineage within the genus . Combined genotypic and phenotypic data showed that strain US15 (=DSM 16915=KCTC 19080) merits recognition as the type strain of a novel species within the genus , for which the name sp. nov. is proposed.
