Abstract

This study reports that candicidin-like secondary metabolites produced by microbial cells in natural soil environments can effectively control soilborne fungal diseases, revealing a novel mechanism of microbial biocontrol agents. We demonstrated that the main antifungal activity and biocontrol activity of Streptomyces albidoflavus strain W68 are attributable to the production of candicidin isomers, suggesting that gene clusters for candicidin-like compound biosynthesis might be used as molecular markers to screen and breed microbial strains for biocontrol agent development.
