Fig. 3From: Enhanced production of antifungal lipopeptide iturin A by Bacillus amyloliquefaciens LL3 through metabolic engineering and culture conditions optimizationInhibitory effect picture (a) and inhibition ratio (b) of iturin A produced by B. amyloliquefaciens C2LP. Samples A.a, B.c, C.g, F.o and R.s correspond to A. alternate, B. cinerea, C. gloeosporioides, F. oxysporum and R. solani, respectively. Each well on the right was filled with 60 μl of the iturin A extract from C2LP, and 60 μl of sterile fermentation medium as a control was added to the well on the left. Data are reported as mean values of the inhibition ratio from three independent experimentsBack to article page
