Degradation of flavipin by Monilinia laxa
Monilinia laxa, a pathogen of peach trees, was found to metabolize the antibiotic flavipin, from Epicoccum nigrum. This was demonstrated by a decrease in inhibitory activity, assessed in a germination assay of M. laxa, when culture medium containing flavipin was inoculated with M. laxa, compared with controls without fungus or with dead fungus. A similar decrease of activity was found on thin-layer chromatograms sprayed with Cladosporium cucumerinum, and reduction of flavipin content after growth of M. laxa was confirmed by hplc. When M. laxa was incubated with a high concentration of flavipin, it apparently metabolized the compound to other substances inhibitory to C. cucumerinum on chromatograms. © 1993, British Mycological Society.
