RECOMBINANT STRAIN PRODUCING L-AMINO ACIDS, CONSTRUCTING METHOD THEREFOR AND METHOD FOR PRODUCING L-AMINO ACIDS.

摘要

Provided is a recombinant strain producing L-amino acids, a constructing method therefor and a method for producing L-amino acids. Compared with the starting strains, the recombinant strain producing L-amino acids has decreased expression of 6-phosphoglucose isomerase Pgi and increased expression of 6-phosphogluconate dehydrogenase Zwf-OpcA. The starting strain can accumulate objective amino acids. Fermentation culturing of the recombinant strain can increase the yield of L-amino acids significantly. Also provided is a novel method for increasing the fermentation yield of L-amino acids, capable of being be used in bacterial fermentation of L-amino acids.
