Abstract                 

The present study was designed to evaluate the antimicrobial potential of the fruiting body of Pleurotus ostreatus against several pathogenic microorganisms. The fruiting body powder of Pleurotus ostreatus was extracted with different organic solvents viz. benzene, chloroform, acetone, ethanol, methanol, and in distilled water by maceration method in the order of increasing solvent polarity. Using the agar well diffusion technique, the extracts were tested for their antimicrobial activity against four Gram positive (Bacillus subtilis, Micrococcus luteus, Staphylococcus aureus, Staphylococcus epidermidis) and seven Gram negative (Aeromonas hydrophila, Alcaligenes faecalis, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella typhimurium) bacterial strains. Four standard antibiotics viz., streptomycin, penicillin, tetracycline and ampicillin were also tested against all the bacterial strains for comparison of the results with the crude extracts; and it was found that a few extracts were more effective than the antibiotics. Zone of inhibition for the various extracts varied between 6.5 to 14 mm; ethanol extract exhibiting maximum antimicrobial activity against most of the tested pathogens. Among the microorganisms tested, Pseudomonas aeruginosa, Aeromonas hydrophila, Staphylococcus aureus and Salmonella typhimurium were found to be more susceptible to the extracts as compared to the other microbes.
