The use of yeast for microbial degradation of some selected mycotoxins

Abstract

Several biodegradation experiments were carried out using 10 different yeast strains.Saccharomyces spp., Kluyveromyces spp. andRhodotorula spp. were tested for biodegradation of selected mycotoxins (ochratoxin A, nivalenol, deoxynivalenol and fumonisin B1) standardsin vitro. There was confirmed that some yeast strains are able to degrade some mycotoxins. However, great differences between individual strains were observed. Moreover, 12Saccharomyces cerevisiae strains were tested for their potential capability to degrade zearalenone and fumonisins in Sabouraud broth. Two strains were capable to degrade zearalenone totally, one strain decreased the mycotoxin concentration up to 25%, and one strain up to 75% of original amount. Two strains were capable to degrade fumonisins partially.

Interaction of aflatoxin B1and fumonisin B1in mice causes immunotoxicity and oxidative stress: Possible protective role using lactic acid bacteria

“…Many micro-organisms, e.g. bacteria, yeasts, molds, actinomycetes, are able to remove or degrade small amounts of mycotoxins in food/ feed (Styriak et al, 2001). Results of several studies suggest that binding is the main mechanism of detoxification (Gratz, 2007).…”

“…Many micro-organisms, including bacteria, yeasts, molds, actinomycetes, and algae, are able to remove or degrade small amounts of aflatoxin in food/feed (Styriak et al, 2001). Results of several studies suggest that binding is the main mechanism of detoxification against aflatoxins (Niderkorn et al, 2006;Gratz, 2007).…”
