A xylan-degrading bacterium, strain X11-1T, was isolated from soil collected in Nan province, Thailand. The strain was characterized based on its phenotypic and genotypic characteristics. Strain X11-1T was a Gram-stain-positive, facultatively anaerobic, spore-forming, rod-shaped bacterium. It contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-7, anteiso-C15:0 (56.6 %) and C 16:0 (14.0 %) were the predominant cellular fatty acids and diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol were the major phospholipids. The DNA G+C content was 51.6 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain X11-1T was affiliated to the genus Paenibacillus and was closely related to Paenibacillus naphthalenovorans KACC 11505T and Paenibacillus validus CCM 3894T, with 96.5% sequence similarity. Therefore, the strain represents a novel species of the genus Paenibacillus, for which the name Paenibacillus xylanisolvens sp. nov. is proposed. The type strain is X11-1T (=KCTC 13042T =PCU 311T =TISTR 1829T).
