Clostridium acetobutylicum

Clostridium acetobutylicum, ATCC 824, is a commercially valuable bacterium sometimes called the "Weizmann Organism", after Jewish-Russian born Chaim Weizmann, then senior lecturer at the University of Manchester, England, used them in 1916 as a bio-chemical tool to produce at the same time, jointly, acetone, ethanol, and butanol from starch. The method was described since as the ABE process, (Acetone Butanol Ethanol fermentation process), yielding 3 parts of acetone, 6 of butanol and 1 of ethanol, reducing the former difficulties to make cordite, an explosive, from acetone and paving the way also, for instance, to obtain vehicle fuels and synthetic rubber.

Unlike yeast, which can digest sugar only into alcohol and carbon dioxide, C. acetobutylicum and other Clostridia can digest whey, sugar, starch, and perhaps certain types of lignin, yielding butanol, propionic acid, ether, and glycerin.

In genetic engineering

James Liao, a chemical engineer at the University of California, Los Angeles developed a method to insert genes from Clostridium acetobutylicum, which are responsible for production of butanol into the bacterium Escherichia coli. [1] [2]
