RESUMO
Endophytic fungi colonize the interior of plants without causing damage and act in symbiosis with their host. They are also potential sources of compounds with potential applications in industry, agriculture, and medicine, Thus, this study aimed to isolate and identify the endophytic fungi medicinal plant Talinum triangulare and evaluate its potential for the production of antimicrobial substances using the disk diffusion technique and testing in liquid medium front of Staphylococcus aureus ATCC SA 6538, Pseudomonas aeruginosa ATCC PA 0030, and Corynebacterium diphtheria ATCC 27012. Corynebacterium diphtheria was isolated from 3 fungi of the genus Trichoderma and Penicillium, with only the genus Trichoderma fungi showing antimicrobial activity.
