摘要
The present invention relates to a succinic acid-producing mutant microorganism that is able to utilize sucrose and glycerol simultaneously as carbon sources. More particularly, the present invention relates to a succinic acid-producing mutant microorganism that is able to utilize sucrose and glycerol simultaneously for succinic acid production, the mutant organism being obtained by relieving the mechanism of sucrose-mediated catabolite repression of glycerol in a succinic acid-producing microorganism. As described above, when the succinic acid-producing mutant microorganism is cultured, it utilizes sucrose and glycerol simultaneously so that succinic acid can be produced with high productivity in a maximum yield approaching the theoretical yield while the production of byproducts is minimized. In addition, according to the present invention, various reduced chemicals which have been produced in low yields in conventional methods can be more effectively produced.
