Characterization of growth in the L. casei and L. casei ΔPyrR strains. (A) The growth curves of L. casei and L. casei ΔPyrR strains grow in the MRS media. The curves were calculated via Standard Plate Count (SPC) every 2 h, respectively. (B) To measure 5-FOA resistance, the wild-type and mutant cells were grown on MRS plates with 10 mM 5-FOA and incubated for 5 days.
