Chaim Weizmann

Detailed explanation-1: -At this time Chaim Weizmann became involved in the development of this process. He isolated a new bacterial culture, readily fermenting starchy material into acetone and butanol. Clostridium acetobutylicum was the main species in this culture.
Detailed explanation-2: -It usually uses a strain of bacteria from the Class Clostridia (Family Clostridiaceae). Clostridium acetobutylicum is the most well-studied and widely used.
Detailed explanation-3: -The Weizmann process was developed at the beginning of the 20th century for the biological conversion of corn into acetone and n-butanol by Clostridium acetobutylicum1, 2, 3. It was the second largest fermentation process (after ethanol) of enormous industrial, social and historical importance1, 2, 3.
Detailed explanation-4: -Acetone carboxylation (Acx) was initially characterized in the aerobic acetone-degrading alphaproteobacterium Xanthobacter autotrophicus and in the anoxygenic phototrophic bacterium Rhodobacter capsulatus (1–3, 21–23).
