The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

A bacterial strain, TR7-06T, which has cellulase and β-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 Cellulomonas, with highest sequence similarity to Cellulomonas uda DSM 20107T (98.5%). Cell wall analysis revealed the presence of type A4β, L-Orn-D-Glu peptidoglycan. The cell-wall sugars detected were mannose and glucose. The predominant menaquinone was MK-9(H4); MK-8(H4) was detected in smaller quantities. The major fatty acids were anteiso-C15:0, C16:0, C14:0 and C18:0. The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The results of DNA-DNA hybridization and physiological and biochemical tests clearly demonstrated that TR7-06T represents a novel species. The combined genotypic and phenotypic data show that strain TR7-06T (=KCTC 19030T =NBRC 100758T) merits description as the type strain of a novel Cellulomonas species, Cellulomonas composti sp. nov. © 2007 IUMS.
