Abstract In the current work, the gymnosperm plants of Catharanthus roseus and Vitex negundo were used to extract the bioactive endophytic fungus species. Based on physical traits, the isolated fungus species was identified as Xylaria sp. SR2. Phoma sp. S2. The Xylaria AND Phoma sp. fungal isolate was cultivated in a variety of pH ranges and culture medium in order to maximise biomass output under submerged culture circumstances. The ideal temperature and pH for the highest mycelial development were discovered to be 30°C and 5.5, respectively, in PDA, where the maximum growth of Xylaria sp. SR2 AND Phoma sp. was seen. The drug-resistant Pseudomonas syrirgae (MTCC 673) and Proteus mirabilis (MTCC1429), Burkholderi aglumae (MTCC8496) and Moraxella bovis (MTCC 1775) strains were tested to antibacterial activity using the improved ethyl acetate extract of the culture filtrate.
