ANTIFUNGAL ACTIVITYOF MICROBIAL METABOLITES AGAINST Colletotrichum gloesporioides

Abstract

The objective of the present study was to evaluate in vitro the concentrated fraction of secondary metabolites produced by the Bacillus bacteria cereus against the phytopathogenic fungus Colletotrichum gloesporioides. Using the agar diffusion technique and the characterization of secondary metabolites using gas chromatography coupled to mass spectrometry (GC–MS) technique. Results: The microbial metabolites extracted from Bacillus cereus presented a 48% inhibition percentage and geraniol, geranate and sulcatone were identified, which presented in vitro antagonism against C. gloesporioides phytopathogen of agricultural interest at regional, national and international levels. Conclusion. The production of microbial secondary metabolites in the future may be an environmentally friendly biological alternative to replace agrochemicals.
