Abstract : Endophytic fungi are the coloniser of healthy plant tissues that get nutrition and shelter from host and in response produce many functional metabolites.These metabolites have anti-feedant activity and provide resistance against various biotic and abiotic stresses,and which may enhance the host fitness.many reports are there that endophytes in medicinal plants have antimicrobial, antioxidant as well as anti-cancerous property. In the present study two major endophytic fungal organisms were isolated from the leaves of Cassia alata,based on the morphological characters they were identified as Aspergillus species and Penicillium species. The significance of the study is exploiting the endophytic fungi in the area of microbial diversity realising the capability of microorganism to produce diverse bioactive molecules and the existence of unexplored microbial diversity, research is under way to isolate and screen microbes of diverse habitat and unique environment for discovery of novel metabolites. The isolates were then screened for their antibacterial activities. On the basis of antimicrobial activities of mycelia mass, free extract broth solution of fungal endophytes, it was evident that they shows significant antibacterial activity against almost all bacterial pathogens, Penicillium species, is more effective than Aspergillus species in terms of zone of inhibition produced against pathogens.
