Metabolite fraction from B. velezensis liquid culture demonstrates antimicrobial activity. a The antimicrobial disc (left) was prepared by adding 50 μL of fraction to filter paper, and placed onto an LB agar plate spread with C. michiganensis. The control disc (right) used acetonitrile in place of the metabolite fraction. b Antimicrobial discs with surfactin concentrations between 1 mg/mL and 10 mg/mL were placed onto an LB agar plate spread with P. syringae DC3000. c Antimicrobial discs with surfactin concentrations between 1 mg/mL and 10 mg/mL were placed onto an LB agar containing a central agar plug of C. carbonum
