Effects of lrpC deletion on bacitracin synthesis. A: Deletion of lrpC improved bacitracin yield, B: The transcriptional level of BCAA transporter gene brnQ, C: The schematic diagram of GFP expression vector mediated by promoter PbrnQ, D: The green fluorescence intensities of recombinant strains. Each experiment was repeated at least three times, and data are represented as the means of three replicates and bars represent the standard deviations, ∗, P ​< ​0.05; and ∗∗, P ​< ​0.01 indicate the significance levels between recombinant strains and control strain.
