Aspergillus niger capable of rapidly degrading zearalenone and application of aspergillus niger

Abstract

The invention discloses aspergillus niger capable of rapidly degrading zearalenone and application of the aspergillus niger, and belongs to the field of microorganisms. According to the invention, a strain of capable of effectively degrading the zearalenone is screened out by performing capable of effectively degrading zearalenone is screened out on original aspergillus niger. The strain has highbinding speed with zearalenone and high degradation efficiency, and can degrade 95% or more of the zearalenone within 28h; a relatively high degradation effect can be achieved by using a relatively small amount of zearalenone; degradation of the same concentration of zearalenone needs 1 / 10 of the use amount of the original strain, and the strain is a food-grade strain; and the aspergillus niger can be used for degrading zearalenone in cereals such as corn and barley.

Description

technical field

[0001] The invention relates to a strain of Aspergillus niger capable of rapidly degrading zearalenone and an application thereof, belonging to the field of microorganisms. Background technique

[0002] Zearalenone (Zearalenone, ZEN) is a class of Fusarium mycotoxins with a wide range of contamination and estrogen-like activity. ZEN can widely pollute corn, grains and other food crops around the world, which not only brings huge economic losses to the food and feed industry, but also can accumulate in animals or humans through the food chain, causing acute poisoning and death in animals or humans. Chronic poisoning. Many studies have shown that zearalenone can not only cause human and animal reproductive system disorders, but also has strong immunotoxicity, cytotoxicity and liver toxicity, and can enter the food chain through contaminated crops, and long-term consumption of contaminated crops Food may also cause cancer, which seriously threatens the health ...
