Latest Patents

Choi's latest patents include two groundbreaking inventions. The first patent is for a "Homo-succinic acid producing microorganism variant and process for preparing succinic acid using the same." This invention relates to microbial variants that produce homo-succinic acid at high yields. It specifically involves a microbial variant constructed by disrupting a lactate dehydrogenase-encoding gene (idhA) and an acetate kinase-encoding gene (ackA). The method for producing homo-succinic acid involves culturing these variants using glucose as a carbon source under anaerobic conditions.

The second patent is for a "Mutant microorganism producing succinic acid simultaneously using sucrose and glycerol, and method for preparing succinic acid using same." This invention describes a succinic acid-producing mutant microorganism capable of utilizing both sucrose and glycerol simultaneously as carbon sources. The mutant organism is developed by relieving the mechanism of sucrose-mediated catabolite repression of glycerol in a succinic acid-producing microorganism. This innovative approach allows for high productivity in succinic acid production while minimizing byproducts.
