ABSTRACT: The methanol extract of an edible mushroom, Pleurotus highking with its whole parts, cap and stipe individually were subjected for the evaluation of antimicrobial activities against a series of pathogenic microorganisms. Three Gram positive (Bacillus cereus, Streptococcus agalactiae and Agrobacterium), three Gram negative (Pseudomonas aeruginosa, Escherichia coli and Shigella dysenteriae) and three pathogenic fungus (Aspergillus niger, Saccharromyces cerevaceae and Candida albicans) were used as test pathogen. Disc diffusion assay method was employed for our experimental purpose. All the tested Gram positive strains were sensitive to 200μg of extracts/disc while there was no sensitive to Gram negative strain, Escherichia coli and Shigella dysenteriae. A tested Gram negative strain, Pseudomonas aeruginosa also sensitive to the extracts at a concentration of 200μg/disc. Aspergillus niger and Candida albicans were susceptible to methanol extract of Pleurotus highking while Saccharromyces cerevaceae was resistant to it. However, the susceptibility of the extracts from different parts was varied. The extract from cap showed prominent antimicrobial activity as compared to whole mushroom and stipe.
