Clostridium 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 کاملClostridium phytofermentans sp. nov., a cellulolytic mesophile from forest soil.
An obligately anaerobic, mesophilic, cellulolytic bacterium, strain ISDgT, was isolated from forest soil. Cells of this isolate stained Gram-negative, despite possessing a Gram-positive cell-wall ultrastructure, and were motile, straight rods that formed spherical terminal spores that swelled the sporangium. Cellulose, pectin, polygalacturonic acid, starch, xylan, arabinose, cellobiose, fructos...
متن کاملImprovement of cellulolytic properties of Clostridium cellulolyticum by metabolic engineering.
Cellulolytic clostridia have evolved to catabolize lignocellulosic materials at a seasonal biorhythm, so their biotechnological exploitation requires genetic improvements. As high carbon flux leads to pyruvate accumulation, which is responsible for the cessation of growth of Clostridium cellulolyticum, this accumulation is decreased by heterologous expression of pyruvate decarboxylase and alcoh...
متن کاملClostridium aldenense sp. nov. and Clostridium citroniae sp. nov. isolated from human clinical infections.
One hundred eight isolates were previously identified in our laboratory as Clostridium clostridioforme by colonial and cellular morphology, as well as biochemical tests. Recent studies have indicated that there are actually three different species in this C. clostridioforme group: C. hathewayi, C. bolteae, and C. clostridioforme. Our isolates were reexamined using biochemical and enzymatic test...
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 ...
