乳酸菌去除脱氧雪腐镰刀菌烯醇的研究进展

Progress in removal of deoxynivalenol by Lactobacillus

脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON)是由镰刀菌属产生的真菌毒素,具有肠道和免疫毒性,在谷物和饲料中污染严重,威胁人类和动物的健康。利用微生物法去除真菌毒素特异性强,效率高且对环境安全,被广泛应用。乳酸菌作为一种益生菌,具有去除DON的能力,同时不会影响产品的品质,成为近年来去除DON的研究热点。本文主要阐述了具有去除DON能力的乳酸菌种类及乳酸菌去除DON的机制,并通过对比其他细菌降解DON的机制和降解酶,推测乳酸菌中可能存在生物降解作用,并对乳酸菌去除DON的应用前景进行了展望。

Deoxynivalenol(DON)is a mycotoxin produced by Fusarium,which has intestinal and im?mune toxicity.DON is heavily polluted in grain and feed and seriously threatens human and animal health.Microbial method is widely used to remove mycotoxins because of its high specificity,high effi?ciency and environmental safety.Lactobacillus sp.,as a probiotic bacterium,have the ability to remove DON without affecting the quality of products,which has become a research focus in recent years.In this paper,the species of Lacto?bacillus sp.with the ability to remove DON and their mechanism of removing DON were de?scribed.By comparing the mechanisms and deg?radation enzymes of other bacteria to degrade DON,it was speculated that there might be biodegradation in Lactobacillus sp..The application of DON removal byLactobacillus sp.was also prospected.
