Abstract

A bacterial strain, TR7-06, which has cellulase and -glucosidase activities, was isolated from compost at a cattle farm near Daejeon, Republic of Korea. It was a Gram-positive, aerobic or facultatively anaerobic, non-motile, rod-shaped bacterium. Phylogenetic analysis based on 16S rRNA gene sequences showed that this strain belongs to the genus , with highest sequence similarity to DSM 20107 (98.5 %). Cell wall analysis revealed the presence of type A4, -orn–-Glu peptidoglycan. The cell-wall sugars detected were mannose and glucose. The predominant menaquinone was MK-9(H); MK-8(H) was detected in smaller quantities. The major fatty acids were anteiso-C, C, C and C. The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that TR7-06 represents a novel species. The combined genotypic and phenotypic data show that strain TR7-06 (=KCTC 19030=NBRC 100758) merits description as the type strain of a novel species, sp. nov.
