ROS-scavenging activities of the cell free extracts from Corynebacterium glutamicum strains. The cell extracts from the C. glutamicum wild-type strains carrying empty vector, pcaIJ-expressing vector, pcaFD-expressing vector, and pcaHGBC-expressing vector are indicated as WT, +pcaIJ, +pcaFD, and + pcaHGBC, respectively. Cells were harvested at OD = 10 in the BHI medium for cell extract preparations.
