TH44466A - Methods for L-Glutamic Acid Production - Google Patents

Abstract

DC60 (08/06/43) L-glutamic acid is produced more efficiently and cheaply compared to previously used techniques by culturing Coryneform bacteria, which are capable of producing L-glutamic acid, in the medium. This involves producing and accumulating L-glutamic acid in the medium and collecting it from the medium, with the L-glutamic acid uptake system being deficient or reduced in the Coryneform bacteria.

Claims (3)

1.Methods for L-Glutabic Acid Production Composed of Corine Form Bacterial Breeding Process Where L-glutamic acid is able to be produced in the medium to produce and accumulate L-glutamic acid in that medium and for collection of L-glutamic acid from the medium, with the intake system L-glutamic acid is deducted or reduced in the bacterial corene form, where the L-glutamic acid intake system is encoded by the gluABCD operon and by the way. One of the products from the gluABCD expression, the operons were removed in the corine form bacteria. 2. Methods according to claim 1, where at least gluA was removed in the corine form bacteria. 3. Claim Method 2, where all of the gluA, gluB, gluC, and gluD were removed in the corine form.
