Abstract

The invention discloses a fermentation agent for degrading aflatoxin, and a preparation method and application thereof, and belongs to the technical field of toxin degradation. The fermentation agentfor degrading the aflatoxin is formed by a compound microbial agent and a synergist according to the weight-to-volume ratio of 4:1, and the compound microbial agent is formed by Streptococcus thermophilus, bifidobacterium, candida utilis and bacillus licheniformis which are mixed according to the weight ratio of (1-5):(1-5):(3-8):(3-8). The fermentation agent can effectively degrade the aflatoxinB1 in crops or agricultural products, and a degraded product is safe and does not generate the toxic effect on animal bodies.

Description

technical field [0001] The invention belongs to the technical field of toxin degradation, and in particular relates to a starter for degrading aflatoxin, its preparation method and application. Background technique [0002] Aflatoxins are mainly secondary metabolites produced by Aspergillus flavus (A.flavus) and Aspergillus parasiticus (A.parasiticus), which are derivatives of dihydrofuranocoumarins, and were approved by the World Health Organization (WHO) in 1993. Cancer Research Institute delineated as a class I carcinogen. [0003] Traditionally, physical and chemical methods are used to treat aflatoxin-contaminated agricultural products or feeds; however, these methods have problems such as incomplete detoxification, reduced nutritional value, high cost, and poor applicability. In recent years, biological control of aflatoxin pollution has become a research hotspot. Many microorganisms that inhibit the growth of Aspergillus flavus, inhibit the production of toxins by As...
