What did Chaim Weizmann invent?
Chaim Weizmann invented a fermentation process that converted starch – a poly-sugar readily available from corn and potatoes – into acetone and butyl alcohol, facilitated by a bacteria, Clostridium acetobutylicum, that Dr. Weizmann had previously isolated.

Where is Clostridium acetobutylicum found?
soil dwelling
Clostridium acetobutylicum is a Gram-positive bacillus (1). C. acetobutylicum is most often soil dwelling, although it has been found in a number of different environments. It is mesophilic with optimal temperatures of 10-65°C.
Who invented ABE fermentation?
Weizmann
After just more than 100 years of history of industrial acetone–butanol–ethanol (ABE) fermentation, patented by Weizmann in the UK in 1915, butanol is again today considered a promising biofuel alternative based on several advantages compared to the more established biofuels ethanol and methanol.
Who is the father of Israel in the Bible?
Abraham is known as the “father of Israel” because God appeared to him and promised that his progeny would become “a great nation.” Yet Abraham is much more than the patriarch of a select group of ancient people.

How does ABE fermentation work?
The ABE fermentation is a biphasic process that converts sugars into acids (acetate, butyrate) and solvents (acetone, butanol, ethanol). During the first phase, acidogenesis, the primary products are the acidic metabolites. As the metabolism shifts to solventogenesis, the acids are assimilated into the ABE solvents.
