Abstract
Fungi associated with mangroves are untapped sources of bioactive secondary metabolites. In this study, 628 mangrove leaf endophytic fungi (MLEF) were recorded from 19 mangrove hosts collected from the provinces of Zambales, Batangas, Cavite, and Quezon in Luzon Island, Philippines. The MLEF morphospecies were identified as belonging to the genera Aspergillus, Cladosporium, Colletotrichum, Fusarium, Nigrospora, Penicillium, Pestalotiopsis, Phialophora, and Trichoderma. Screening revealed that the MLEF crude culture extracts were promisingly potent against the gram-positive bacteria Staphylococcus aureus and Micrococcus luteus (ZOI > 19 mm) with no or partial activity against the gram-negative bacteria Klebsiella oxytoca and Pseudomonas aeruginosa. Our findings showed that mangrove leaf endophytic fungi are potential sources of bioactive compounds.
