A novel xylan-degrading bacterium, designated XDB9T, was isolated from forest humus collected from Gyeryong Mountain in Korea. Cells were Gram-positive, aerobic, motile and endosporeforming rods. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain XDB9T was most closely related to members of the genus Lysinibacillus. 16S rRNA gene sequence similarities between strain XDB9T and the type strains of species of the genus Lysinibacillus ranged from 98.0 to 98.5 %. The cell-wall peptidoglycan type of strain XDB9T was A4α, which is based on L-Lys-D-Asp. Strain XDB9T contained iso-C15:0 and C16:1ω7c alcohol as the major fatty acids and MK-7 as the predominant menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 37.2 mol%. The DNA-DNA hybridization results and differential phenotypic properties showed that strain XDB9T could be distinguished from recognized species of the genus Lysinibacillus. It was concluded that strain XDB9T represents a new taxon for which the name Lysinibacillus xylanilyticus sp. nov. is proposed. The type strain is XDB9T (5KCTC 13423T=CCUG 57438T).
