Antimicrobial activity and bioactive compounds of Indian wild Mushrooms

Abstract

Ethanol extracts from the fruiting bodies of three Indian wild mushrooms;<em> Leucopaxillus giganteus</em>, <em> Phellorinia inquinans</em>, and <em>Podaxis pistillaris</em> were investigated for their antimicrobial activities by filter paper disc and well diffusion methods. The extracts inhibited the growth of plant pathogenic bacteria such as <em>Xanthomonas axonopodis </em>pv. <em>punicae</em>, <em>Bacillus pumilus</em>, and <em>Pseudomonas syringe; </em>and plant pathogenic fungi like <em>Aspergillus niger, A. solani</em>um<em>, Alternaria solani</em>, <em>Colletotrichum graminicola</em>, <em>Fusarium oxysporum, F. solani</em>, and <em> Helminthosporium maydis.</em> Well diffusion method gave a better inhibition zone, and the plant pathogenic bacteria were found to be more sensitive to the extracts than the fungi. The minimum inhibition concentration was the least for <em>L. giganteus </em> than <em>P. inquinans </em> and <em> P. pistillaris </em> against the respective plant pathogenic bacteria. In general, ethanol extracts from the fruiting bodies of <em>L. giganteus</em> were found to be superior in antimicrobial activities over the other species investigated. The bioactive compounds in this wild edible mushroom also determined.
