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.
Zusammenfassung
Verschiedene Stämme von Hefen wurdenin vitro zur Biodegradationsstudie herangezogen. ZehnSaccharomyces spp., Kluyveromyces spp. undRhodotorula spp. Stämme wurden auf ihre Biodegradationsfähigkeit ausgewählten Mykotoxinstandards (Ochratoxin A (OA), Nivalenol, Deoxynivalenol und Fumonisin)in vitro getestet. Es konnte gezeigt werden, daß manche Hefestämme imstande sind, einzelne Mykotoxine abzubauen, wobei große Unterschiede zwischen einzelnen Stämmen festgestellt wurden. Zusätzlich wurden 12Saccharomyces cerevisiae Stämme auf ihr potentielles Abbauvermögen von Zearalenon und Fumonisin B1 in einer Nährlösung geprüft. Zwei Stämme waren fähig Zearalenon gänzlich abzubauen, ein Stamm verringerte die anfangskonzentration um 25% und ein weiterer um 75%. Zwei Stämme konnten Fumonisin teilweise abbauen.
