title: Antimicrobial activities of secondary metabolites produced by endophytic fungi from Spondias mombin.
abstract: We performed a search for bioactive compounds produced by fungal endophytes from Spondias mombin (Anacardiaceae). Culture broth extracts of Guignardia sp., Phomopsis sp. and Pestalotiopsis guepinii were separated by chromatographic methods and tested for biological activities. The crude extracts of these endophytes were tested against fourteen organisms, including actinomycetes, Gram-negative and Gram-positive bacteria, yeast, and filamentous fungi. All fungal extracts inhibited actinomycete growth. Guignardia sp. was also active against Escherichia coli, Staphylococcus aureus, Saccharomyces cerevisiae, Geotrichum sp., and Penicillium canadensis. Culture extracts of P. guepinii were active against S. cerevisae, while strains of Phomopsis sp. showed a pronounced antifungal effect against Cladosporium elatum, Mycotypha sp. and S. cerevisae.
