Antimicrobial activity and bioactive compounds of Indian wild Mushrooms

Feleke, Hirut Tsegaye; Doshi, Anila

Abstract

Ethanol extracts from the fruiting bodies of three Indian wild mushrooms; Leucopaxillus giganteus, Phellorinia inquinans, and Podaxis pistillaris 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 Xanthomonas axonopodis pv. punicae, Bacillus pumilus, and Pseudomonas syringe; and plant pathogenic fungi like Aspergillus niger, A. solanium, Alternaria solani, Colletotrichum graminicola, Fusarium oxysporum, F. solani, and Helminthosporium maydis. 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 L. giganteus than P. inquinans and P. pistillaris against the respective plant pathogenic bacteria. In general, ethanol extracts from the fruiting bodies of L. giganteus were found to be superior in antimicrobial activities over the other species investigated. The bioactive compounds in this wild edible
mushroom also determined.
