Sažetak
Trichothecium roseum, a mold commonly associated with Aspergillus flavus in damaged soy- beans, interferes with production of aflatoxins when grown with A.flavus on autoclaved soy-beans.The pH of soy-beans meal disks was adjusted using NaOH-HCl, citric acid-sodium citrate, or water extracts of T.roseum fermented soy-beans.Aflatoxin formation was completely inhibited below pH 2.5-3.5, irrespective of the system used for pH adjustment.When grown in association with A.flavus ATCC 26949 on autoclaved soy-beans.T.roseum lowered substrate pH sufficiently to suppress aflatoxin B1 and G1 production.The biodegradation of aflatoxin B1 and G1 were eliminated as potential mechanisms by which T.roseum reduces aflatoxin contamination.A water extract of soy-beans fermented with T.roseum caused an additional inhibition of aflatoxin formation apart from the effects of pH.
