Antibacterial activity of some endophytic fungi isolated from Cyprus rotundus L.

Abstract

During present study attempt were made to screened antibacterial activity of endophytic fungi isolated from Cyprus rotundus L. Endophytic fungi viz., Aspergillus niger, A. flavus, A. fumigates, Alternaria alternate, Fusarium oxysporum, Rhizoctonia oryzae, Cladosporium harbaroids, Curvularia clavata, and Penicillium citrinum were isolated from different parts of Cyprus rotundus. Aspergillus niger, Alternaria alternata, Fusarium oxysporum and Penicillium citrinum were selected for present study. The efficiency of extract was tested against five human pathogenic bacteria viz. Staphylococcus aureus, Salmonella typhimurium, Pseudomonas aeruginosa, Shigella flexneri and Escherichia coli. The extract showed remarkable antibacterial activity against tested bacteria. This activity of endophytic fungi may due to presence of different secondary metabolites
