Clostridium acetobutylicum, ATCC 824, is a commercially valuable bacterium sometimes called the "Weizmann Organism", after Jewish Russian-born biochemist Chaim Weizmann. (wikipedia.org)
Clostridium thermocellum is an anaerobic thermophilic bacterium that exhibits high levels of cellulose solublization and produces ethanol as an end product of its metabolism. (biomedcentral.com)
Clostridium thermocellum is an anaerobic soil bacterium that is of particular interest due to its complexed cellulase system and its ability to rapidly solubilize cellulosic material and produce ethanol [ 1 ]. (biomedcentral.com)
Bacillus1
Bacterial spores are produced by Gram-positive bacteria including members of the Bacillus and Clostridium genera, and are widely understood to be dormant cell forms that remain viable for long periods of time until growth conditions become favorable. (biomedcentral.com)
Butanol1
Unlike yeast, which can digest only some sugars into alcohol and carbon dioxide, C. acetobutylicum and other Clostridia can digest whey, sugar, starch, cellulose and perhaps certain types of lignin, yielding n-butanol, propionic acid, ether, and glycerin. (wikipedia.org)
Like all clostridia, this organism forms terminal endospores, which confer a high degree of resistance to heat, desiccation and other environmental challenges. (biomedcentral.com)
