Abstract: The present study aims to isolate endophytic fungi present in Morinda correia and screen for their antimicrobial activity. Colletotrichum gloeosporioides and Alternaria tenuissima were isolated from leaves of M. correia and identified through morphological and molecular methods. Both the organism were grown in Czapek’sdox broth medium and extracted with ethyl acetate. The ethyl acetate extract was tested for antimicrobial activity by disc diffusion method. Maximum inhibitory activity was identified towards Staphylococcus aureus by extract of C. gloeosporioides. Further investigation was carried out to identify the bioactive components produced by C. gloeosporioides using GC-MS. This study demonstrates the potential of isolated endophytic fungi from M. correia for the control of human pathogens.
