Chaim Azriel Weizmann (/ ˈ k aɪ m ˈ w aɪ t s m ə n / KYME WYTE-smən; [a] 27 November 1874 – 9 November 1952) was a Russian-born Israeli statesman, biochemist, and Zionist leader who served as president of the Zionist Organization and later as the first president of Israel.
Pathway of acetone–butanol–ethanol fermentation by clostridia. Acetone–butanol–ethanol (ABE) fermentation, also known as the Weizmann process, is a process that uses bacterial fermentation to produce acetone, n-butanol, and ethanol from carbohydrates such as starch and glucose.
The Commercial Solvents Corporation was established at the end of World War I; earning distinction as the pioneer producer of acetone and butanol by fermentation processes developed and patented by Dr. Chaim Weizmann.
Chaim Weizmann. Production of Cordite required large volumes of the solvent acetone and this was in short supply. At the time, acetone was manufactured by destructive distillation of wood. Chaim Weizmann had developed a process of bacterial fermentation, using Clostridium acetobutylicum, in 1912 but it did not appear to have any commercial value.
Acetone for the cordite industry during late World War I was eventually produced through the efforts of Dr. Chaim Weizmann, considered to be the father of industrial fermentation. While a lecturer at Manchester University Weizmann discovered how to use bacterial fermentation to produce large quantities of many desired substances.
In 1916, biochemist and future first president of Israel Chaim Weizmann was the first to isolate Clostridium acetobutylicum, a Gram-positive, anaerobic bacteria in which acetoacetate decarboxylase is found. Weizmann was able to harness the organism's ability to yield acetone from starch in order to mass-produce explosives during the war. [3]
Clostridium acetobutylicum, ATCC 824, is a commercially valuable bacterium sometimes called the "Weizmann Organism", after Jewish Russian-born biochemist Chaim Weizmann. A senior lecturer at the University of Manchester , England , he used them in 1916 as a bio-chemical tool to produce at the same time, jointly, acetone , ethanol , and n ...
Arthur and the Acetone (1936) is a satirical playlet by George Bernard Shaw which dramatises an imaginary conversation between the Zionist Chaim Weizmann and the British Foreign Secretary Arthur Balfour, which Shaw presents as the "true" story of how the Balfour Declaration came into being.
