AI Technical Summary

Technical Problem

Existing technologies cannot effectively address the complex contamination of maize with multiple mycotoxins. The degradation effect of a single strain or a single enzyme is limited and cannot meet the requirement of simultaneous degradation of multiple toxins. Furthermore, there are problems of inter-strain antagonism and enzyme activity inhibition.

Method used

By using a mixed strain of Bacillus natto, Bacillus amyloliquefaciens, Saccharomyces cerevisiae, and Lactobacillus plantarum, combined with solid cellulase and xylanase, the fungal cell walls are destroyed and various toxins are precisely degraded through synergistic action.

Benefits of technology

It achieves highly efficient degradation of aflatoxin B1, zearalenone, vomitoxin, fumonisin B1, and ochratoxin A in corn, with a degradation rate of over 90%, and is safe with no secondary pollution, solving the problem of treating multi-toxin complex pollution.

Abstract

The invention relates to a compound capable of simultaneously degrading multiple corn mycotoxins, and belongs to the technical field of food safety. The compound consists of a mixed strain and a biological enzyme, the mixed strain comprises the following components in percentage by mass: 25%-45% of bacillus natto, 5%-25% of bacillus amyloliquefaciens, 10%-30% of saccharomyces cerevisiae and 10%-30% of lactobacillus plantarum, wherein the total mass of the mixed strain is 100%; the biological enzyme is solid cellulase and xylanase; the compound adopts a biotechnology of synergistic combination of bacteria and enzymes, so that health hazards caused by chemical detoxification are eliminated, and toxic by-products are not generated in the degradation process; the compound disclosed by the invention is added into corn polluted by fungi in proportion, and the compound has a remarkable degradation effect on aflatoxin B1, zearalenone, vomitoxin, fumonisins B1 and ochratoxin A.
