The glutamate-dependent acid resistance system of Escherichia coli and Shigella flexneri is inhibited in vitro by L-trans-pyrrolidine-2,4-dicarboxylic acid.

FEMS microbiology letters - 15 Jul 2003

Waterman Scott R, Small P L C

Abstract excerpt

Strains of Escherichia coli K-12, O157:H7, and Shigella flexneri grown to stationary phase in complex unbuffered media can survive for several hours at pH 2.5. This stationary-phase acid resistance phenotype is dependent upon the alternate sigma factor sigmas and the supplementation of either glutamate or glutamine in the acidified media used for acid challenge. Acid resistance under these defined conditions can...
