Resumo: | Mycotoxins are produced by the secondary metabolism of many fungi and can be found in almost 25% of the world’s agricultural commodities. These compounds are toxic to humans, animals, and plants and therefore, efforts should be made to avoid mycotoxin contamination in food and feed. Besides, up to 25% of all harvested fruits and vegetables are lost due to storage molds and/ or mycotoxin contamination and many methods have been applied to mitigate these issues, but most of them rely on the use of fungicides. Although chemicals are often the first defensive line against mycotoxigenic fungi, the indiscriminate use of fungicides are awakening the public perception due to their noxious effects on the environment and human/animal health. Thus, there is an increasing public pressure for a safer and eco-friendly alternative to control these organisms. In this background, biological control using microbial antagonists such as bacteria, fungi and yeasts have been shown to be a feasible substitute to reduce the use of chemical compounds. Despite of the positive findings using the biocontrol agents only a few products have been registered and are commercially available to control mycotoxin-producing fungi. This review brings about the up-to-date biological control strategies to prevent or reduce harvested commodity damages caused by storage fungi and the contamination of food and feed by mycotoxins. |

Esses compostos são tóxicos a humanos, animais e plantas e, portanto, esforços para evitar a contaminação de micotoxinas em alimentos e rações devem ser feitos. Além disso, até 25% das frutas e legumes em pós-colheita são perdidos em decorrência do ataque de fungos de armazenamento e/ou contaminações por micotoxinas. Vários métodos têm sido aplicados para mitigar os problemas de micotoxinas, mas a maioria deles se baseia no uso de fungicidas. Embora os produtos químicos sejam, muitas vezes, a primeira estratégia de defesa contra fungos micotoxigênicos, o uso indiscriminado de fungicidas vem despertando a percepção pública, em razão de seus efeitos nocivos sobre o meio ambiente e à saúde humana/animal. Assim, existe uma crescente pressão pública em busca de alternativas mais segura e não nocivas ao meio ambiente para controlar estes organismos. Nesse contexto, o controle biológico utilizando antagonistas microbianos, tais como bactérias, fungos e leveduras têm mostrado ser um substituto viável para reduzir a utilização de produtos químicos. Apesar dos resultados positivos, usando os agentes de controle biológico, poucos produtos apenas foram registrados e estão comercialmente disponíveis para controlar fungos produtores de micotoxinas. Esta revisão traz estratégias de controle biológico para evitar ou reduzir danos em commodities agrícolas causadas por fungos de armazenamento e a contaminação de alimentos e rações por micotoxinas.Universidade Federal de Lavras2015-07-24T12:35:49Z2015-07-24T12:35:49Z2012-08-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMEDEIROS, F.
