Abstract

A novel anaerobic, thermophilic and cellulolytic bacterium (strain CSK1) was isolated from a cellulose-degrading bacterial community. On the basis of 16S rRNA gene sequence similarity, strain CSK1 was mapped to cluster III of the genus . Strain CSK1 is closely related to (96·2 %) and (95·1 %). Strain CSK1 is a non-motile, spore-forming, straight or slightly curved rod. The optimum temperature and initial pH for its growth and cellulose degradation are 50–55 °C and pH 7·5. Strain CSK1 grew under a gas phase containing up to 4 % O. Phylogenetic and phenotypic analyses support the differentiation of strain CSK1 from its closest relatives. Strain CSK1 therefore represents a novel species, for which the name sp. nov. is proposed, with CSK1 (=DSM 16021=IAM 15070) as the type strain.
