EVALUATION OF ANTIMICROBIAL ACTIVITY OF SOME OF THE SELECTED BASIDIOMYCETOUS FUNGI

Abstract

The aim of the present study was to evaluate antimicrobial activity of Ganoderma applanatum, Tricholoma giganteum and Bolbitius vitellinus.  The methanolic extract of basidiocarps and mycelial mat of all the above mentioned mushrooms was analyzed. The methanolic extracts were tested against three Gram positive, six Gram negative bacteria and two fungal cultures. Out of three mushrooms Ganoderma applanatum was found to be more active against bacterial cultures, followed by Tricholoma giganteum and Bolbitius vitellinus.  G.applanatum and T.giganteum was found to be more sensitive to Gram Positive bacteria than Gram negative bacteria, however B.vitellinus was found to very active against Gram negative bacteria especially E.coli. B.vitellinus showed highest antifungal activity against Candida albicans, other two mushrooms. Hence these mushrooms can be exploited for their useful metabolites in Food and Pharmaceutical industries.
