Antimicrobial potential of endophytic fungi isolated from the Leaves of Origanum vugare, Psidium guajava and Chrysophyllum cainito.

Endophytic fungi are a group of fungi that live within a plant without causing a disease. They are endosymbionts. This study isolated endophytic fungi from Chrysophyllum cainito (Star apple), Origanum vulgare (Oregano), and Psidium guajava (Guava). Endofungal isolates were grown in a special Potato dextrose agar (PDA) and a colony was selected to prepare a pure culture. Endofungal isolates were tested for antimicrobial activity by agar well diffusion method. All the endofungal isolates displayed significant antimicrobial activity against Staphylococcus aureus and the endophytic fungi in Psidium guajava displayed the strongest antibacterial activity. Results from the present study proves that endophytic fungi could be a promising source of antimicrobial agents.

Objectives

This study determined whether the endophytic fungi found in the leaves of Origanum vulgare, Psidium guajava and Chrysophyllum cainito have an anti-microbial potential when tested against the bacterium Staphylococcus aureus. The study also sought to compare the zone of inhibition of Origanum vulgare, Psidium guajava and Chrysophyllum cainito and if a significant relationship between the zone of inhibition of those three sample endophytic fungi and choramphenicol exists.
