Inhibitory effect of BbMomL on pathogenic factors produced by Pcc and P. aeruginosa PAO1. (A) Relative production of pyocyanin of P. aeruginosa PAO1. (B) Relative protease activity of P. aeruginosa PAO1. (C) Relative pectate lyase activity of Pcc. (D) Relative protease activity of Pcc. The negative control was B. brevis (pNCMO2 transformant). The results shown are representative of biological duplicates. Error bars represent the standard deviations of three replicates. A t-test of unpaired unequal variance was performed for testing differences between groups. For statistical analysis, ***, ** and * indicate P < 0.001, P < 0.01, and P < 0.05, respectively.
