Sažetak
Food and feed safety, due to their direct influence on human health, becomes every day the more and more important issue. The awareness that different chemicals, largely used in agriculture to control pests, could present both environmental problems and health hazard, led to large limitation of their use. Since 2014 European Community has banned about 50% of chemicals used in agriculture. In plant production systems chemicals were also the main tool used against fungal pathogens and against the contamination of food/feed stuff with fungal highly toxic secondary metabolites, mycotoxins. Today the EC push the research to investigate for preventive and/or detoxification strategies using more environmental friendly “green” approaches and eco-compatible tools also in control of plant fungal diseases. Different mushroom metabolites showed the potential to become a control agent for fungal growth and mycotoxin production. One of the most promising biocontrol producers is Trametes versicolor an edible and nontoxic basidiomycete, considered “healing mushroom” for its bioactivity towards some pathologies. Biocontrol agents from T. versicolor, such as polysaccharide Trametano®, oligosaccharides from its partial hydrolysis and protein fractions, are proposed to counteract the growth of some mycotoxigenic fungal species (Aspergillus flavus, A. carbonarius, A. ochraceus) and the mycotoxins synthesis (aflatoxin B1, AF ; ochratoxin A, OTA). The inhibiting effect on germination, fungal growth and toxin synthesis of these compounds was evaluated. Furthermore, some aspects of their mechanism of action is proposed and discussed. The goal of this research is to evaluate an environmental friendly tool for a significant control of mycotoxin production, in order to improve food and feed safety quality. Results indicated that biocontrol agents from T. versicolor could be considered new eco- compatible tools for mycotoxins control, in line with EU directives.
