A bacteria for producing gultamico-l acid and a method for producing glucose-l acid

摘要

It refers to a kind of bacteria producing glucose-l-anhydrides, which belongs to pantoame, entrobater, Klebsiella or Erwinia. After gene recombination, it is changed to stop the activity of rpoS gene, which is encoded as sigma S factor of RNA polymerase, By reducing the expression or disruption of this gene, it also refers to a method for the production of glucoanhydrides, including in bacterial culture, with a pH value of 3-5, through which acid and precipitation in the environment accumulate. Therefore, the efficient production of glutamate can be realized by increasing bacteria.
