Growth inhibitions of Corynebacterium glutamicum strains against oxidative stressors. WT: C. glutamicum wild-type strains carrying empty vector, +pcaIJ: wild-type expressing pcaIJ; +pcaFD: wild-type expressing pcaFD; +pcaHGBC: wild-type expressing pcaHGBC. Vertical bars indicate the kind of oxidative stressors on the each paper disc. The agar plate contained BHI medium and a paper disc contained 20 μL of each stressor. The white bars and numbers indicate the size of each inhibition zone in centimeters.
