Sažetak
Aspergillus flavus are well known ubiquitous fungi able to contaminate both in pre- and postharvest period different feed and food commodities. During their growth these fungi can synthesise aflatoxins, secondary metabolites highly hazardous for animal and human health. These mycotoxins can enter the human food chain by the direct ingestion of contaminated food and by the consumption of animal products coming from livestock fed with contaminated silages. In this work the effect of the basidiomycete Trametes versicolor on the aflatoxin production by A. flavus in maize, was investigated. T. versicolor was grown on pure sugar beet pulp for 14 days at 25°C in dark conditions. The obtained compost was dehydrated at 40°C o/n and powdered. The addition of this fine powder at 1% w/v in maize kernels (moistened up to aw 0.85) significantly (Mann- Whitney test, p<0.001) inhibited up to 85% the production of aflatoxin B1 in maize by A. flavus. Furthermore, treatment of contaminated maize with culture filtrates of T. versicolor containing ligninolytic enzymes, namely laccases at 1U/mg protein, showed a significant reduction of the content of aflatoxin B1 (-70% ; p<0.01). Finally, treated and control maize samples were also compared under in vitro ruminal digestive condition to simulate the possible releasing of aflatoxins upon cow’s digestion. T. versicolor could represent an eco-friendly tool for a significant control of aflatoxin production, in order to obtain feedstuffs and feeds with a higher quality standards.
