Draft Genome Sequence of the Cellulolytic, Mesophilic, Anaerobic Bacterium Clostridium termitidis Strain CT1112 (DSM 5398)
Here, we report the draft genome sequence of Clostridium termitidis strain CT1112 (DSM 5398), a mesophilic, cellulolytic bacterium that can utilize a variety of sugars, as well as pure cellulose, as a sole carbon source; it also synthesizes fermentation end products with potential industrial applications.
متن کاملClostridium cellulolyticum: model organism of mesophilic cellulolytic clostridia.
Clostridium cellulolyticum ATCC 35319 is a non-ruminal mesophilic cellulolytic bacterium originally isolated from decayed grass. As with most truly cellulolytic clostridia, C. cellulolyticum possesses an extracellular multi-enzymatic complex, the cellulosome. The catalytic components of the cellulosome release soluble cello-oligosaccharides from cellulose providing the primary carbon substrates...
متن کاملCellulolytic Activity of Clostridium acetobutylicum.
Clostridium acetobutylicum NRRL B527 and ATCC 824 exhibited extracellular and cell-bound endoglucanase and cellobiase activities during growth in a chemically defined medium with cellobiose as the sole source of carbohydrate. For both strains, the endoglucanase was found to be mainly extracellular (70 to 90%) during growth in continuous or batch cultures with the pH maintained at 5.2, whereas t...
متن کاملCellulolytic and non-cellulolytic bacteria in rat gastrointestinal tracts.
Lactobacillus and Bifidobacterium species were the predominant organisms isolated from small intestinal (jejunal) contents of rats, and lactic acid was the only organic acid detected. The numbers of cellulolytic bacteria in small intestines were low (approximately 10(3)/g). The fermentation in ceca was different from that in intestines, as, in addition to small amounts of lactic acid, high conc...
متن کاملCharacterization of the cellulolytic and hydrogen-producing activities of six mesophilic Clostridium species.
AIMS To characterize cellulolytic, hydrogen-producing clostridia on a comparable basis. METHODS AND RESULTS H(2) production from cellulose by six mesophilic clostridia was characterized in standardized batch experiments using MN301 cellulose, Avicel and cellobiose. Daily H(2) production, substrate degradation, biomass production and the end-point distribution of soluble fermentation products ...
