Antagonistic Effect of Edible Mushroom Extract on Candida Albicans Growth

Abstract

Five species of edible mushrooms, Lentinula edodes, Pleurotus ostreatus, Pholiota nameko, Macrolepiota bonaerensis and Agaricus blazei, were tested for their potential to inhibit the in vitro growth of the pathogenic yeast Candida albicans. Only L. edodes had a fungistatic effect on this human pathogen. The inhibitory compound was produced intra and extracellularly in submersed L. edodes culture, and was also present in fresh and dehydrated mushroom basidiocarps. The fungistatic compound was heat sensitive and lost activity after 72 hours.

Antimicrobial Activity of Mycelia of Oyster Mushroom Species (Pleurotus spp.) and their Liquid Filtrates (In Vitro)

“…Resistant bacteria were appeared in liquid filtrate because of loss some secondary metabolism bioactivity such proteins and polysaccharides by heat when sterilized [17]. Oyster mushrooms enable to produce metabolism products in 48 h to inhibit growth of pathogenic bacteria [18] due to produce polysaccharides, proteins, enzymes and triterpenoides of mycelia of Pleurotus spp.…”

Antimicrobial activity of ethanol extracts ofAgaricus brasiliensisagainst mutans streptococci

“…Few investigations into the antimicrobial activity of medicinal mushrooms have been carried out, and even fewer regarding oral microorganisms (Osaki et al, 1994;Berg et al, 1999;Paccola et al, 2001;Rosa et al, 2003;Grinde et al, 2006;Faccin et al, 2007). Hence, the aim of this article is to report the antimicrobial activity of three ethanol extracts of A. brasiliensis against mutans streptococci.…”

Screening of Brazilian basidiomycetes for antimicrobial activity

“…Despite their potential and enormous diversity in tropical ecosystems (Hawksworth 1991), few studies aiming at the discovery of bioactive compounds from basidiomycetes were conducted in Brazil. Most of the investigations were directed to edible mushrooms (Ishikawa et al 2001, Paccola et al 2001, Oliveira et al 2002 or common, easily recognized species (Smânia et al 1995a(Smânia et al ,b, 1997(Smânia et al , 1999.…”
