Major drawbacks of synthetic chemicals have led to an increase in biocontrol agents used to control phytopathogens. In this study, we investigated Bacillus subtilis strain CU12 and the compounds associated with its antifungal activity. The objectives were to characterize the antifungal activity, to isolate and identify the active compound(s), and to analyze the fungal cellular lipid composition to gain insight into the mode of action of the antimicrobial fengycin. Results showed that B. subtilis CU12 was active against a broad range of phytopathogens with varying sensitivities. One of the antifungal compounds found was 3-hydroxypropionaldehyde (3HPA), which is reported for the first time in B. subtilis. Our results also indicated that sterol content and, to a lesser extent, ratio of anionic/zwitterionic phospholipids may be involved in the mode of action of fengycin produced by B. subtilis CU12. Results from this study are useful in pursuing field testing of the antagonist and essential in the process of potential registration of B. subtilis CU12 as a biocontrol agent.
