Escherichia coli engineering bacteria of N-acetylglucosamine and fermentation production method |
| abstract |
The application relates to the technical field of agricultural biology, in particular to an escherichia coli engineering bacterium of N-acetylglucosamine and a fermentation production method. The invention improves the product precursor supply in the chassis cell of the mutant escherichia coli by cutting off the diversion of glycolysis pathway and pentose phosphate pathway to the N-acetylglucosamine synthesis precursor 6-fructose phosphate, expresses key enzymes of the N-acetylglucosamine synthesis pathway in the chassis cell by utilizing free high-copy plasmids, and produces the N-acetylglucosamine by utilizing the fermentation of a mixed carbon source culture medium, wherein the yield of the N-acetylglucosamine reaches 2.8 g/L. |
