Abstract
Aflatoxins (AFs) contamination in food is a serious problem in the world. Aflatoxin B1 (AFB1), produced by Aspergillusflavus,is secondary metabolite, highly toxic and carcinogenic. The reduction of AFs contamination in food and feed products could be achieved by some microorganisms. In this study,Lactobacillus plantarum ATCC 14917, Lactobacillus curvatus ATCC 1136, Bacillus megateirum A.F.10, Bacillus subtitles A.F.12and commercial probiotic were used to inhibit AFB1 production on yeast extract sucrose medium (YES) and on corn. All bacterial strain inhibitedA. flavusproduction of AFB1 on YES media and corn. Also, commercial probiotics hadthe ability to inhibit A. flavus growth and its production of AFB1 on corn. The most effective bacteria wasB. megaterium A.F.10. It inhibited the fungal growth with 12 mm inhibition zone and inhibits AFB1 production 100% by HPLC on YES media. Determination of AFB1 production by HPLC on corn showed that B. megaterium inhibitedthe production by 69.81% followed by commercial probiotics (59.62%).Commercial probiotics and B. megaterium had a synergistic effect in inhibition ofAFB1 production and in vitro digestion of corn.
