Antimicrobial Activity of Mushrooms

Extract prepared from mushrooms were tested for their antimicrobial activity against E. coli, Klebsiella sp. Three different solvent system like acetone, ethanol, methanol was used for the extraction process. The mushrooms such as Ganoderma lucidum, Pleurotus florida, Calocybe indica were selected for the present study. The antimicrobial study was done. The zone of inhibition observed was compared with standard antibiotics. The zone of inhibition observed was slightly smaller when compared to standard antibiotics. Among the three species selected Ganoderma lucidum showed better zone of inhibition compared to other two. The observed difference in the zone of inhibition might be due to the solvent system used in the extraction process.
