Novel mutant microorganism producing succinic acid simultaneously using sucrose and glycerol, and method for preparing succinic acid using same수크로오즈와 글리세롤을 동시에 이용하는 신규 숙신산 생성 변이 미생물 및 이를 이용한 숙신산 제조방법
Disclosed is a mutant microorganism that is able to utilise sucrose and glycerol simultaneously for succinic acid production, the mutant microorganism being obtained by relieving the mechanism of catabolite repression mechanism of glycerol in a succinic acid producing microorganism, wherein the mutant microorganism is selected from the group consisting of Mannheimia sp., Actinobacillus sp., and Anaerobiospirillum sp.; and wherein relieving the catabolite repression mechanism is performed by deleting a gene encoding fructose phosphotransferase or by introducing a gene encoding glycerol kinase.
