Some of saprophytic bacteria are able to inhibit the biosynthesis of mycotoxins, to regulate the spread of microscopic fungi and have prospects of use for preventing contamination of crop-origin raw material by mycotoxins. According to the results of our study we conclude that bacterial field isolates SB10, SB16 and SB20 have the potency to suppress the production of both aflatoxin B1 and zearalenone. Optimal application amount of the culture medium containing 1 × 10 10 CFU/mL of bacteria was 5 mL per 1 kg of grain, contaminated with fungi that produce these mycotoxins. However, some of the bacteria-antagonists can also have a negative effect on the processed substrate, and it is necessary to take into account when using the product for the purpose of detoxification.
