Abstract
A xylanolytic bacterium, strain S1-3T, was isolated from soil collected in Nan province, Thailand. It was characterized taxonomically based on phenotypic characteristics and 16S rRNA gene sequence comparison. The strain 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. Iso-C16:0 (39.5 %) and anteiso-C15:0 (26.8 %) were predominant cellular fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major polar lipids. The DNA G+C content was 53.3 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain S1-3T was affiliated to the genus Cohnella, and was closely related to Cohnella ginsengisoli GR21-5T and Cohnella thermotolerans CCUG 47242T with 95.7 and 95.3% sequence similarity, respectively. Strain S1-3T could be clearly distinguished from related species of the genus Cohnella by its physiological and biochemical characteristics as well as by its phylogenetic position. Therefore, the strain represents a novel species of the genus Cohnella, for which the name Cohnella thailandensis sp. nov. is proposed. The type strain is S1-3T (=KCTC 22296T =TISTR 1890T =PCU 306T).
