Although the effects of aflatoxin on animal performance have been well established in previous studies, there are few studies reporting on the relationship between aflatoxin and Saccharomyces cerevisiae. The ability of Saccharomyces cerevisiae to minimize aflatoxicosis was evaluated. An aflatoxin-free diet and six contaminated diets (400 lg kg -1 aflatoxin) were formulated with five diets containing the viable yeast (Y1026 or Y904). A 28-day bioassay using 21-day-old and 60-g body weight Wistar rats was conducted. The results showed that there were no significant (P [ 0.05) differences for: food consumption; daily weight gain; food conversion, and enzyme activity. Hepatic tissues from the aflatoxin control group suffered from hepatotoxicity, cellular disorganization, and hepatocyte necrosis. The inclusion of yeast or yeast and amino acids (methionine and cysteine) reduced the toxicity.
O objetivo desta revisão de literatura foi abordar as condições favoráveis ao desenvolvimento de fungos toxigênicos que podem produzir micotoxinas. Os aspectos tratados incluíram temperatura e umidade, agentes competidores e atmosfera de crescimento. Também foram abordados os meios de cultura para identificação de fungos micotoxigênicos. Concluiu-se que o conhecimento dos fatores ligados à produção de micotoxinas possibilita a adoção de medidas para reduzir a presença de toxinas e melhorar o aproveitamento dos alimentos. PALAVRAS-CHAVE: MICOTOXINAS-CONDIÇÕES DE CRESCIMENTO; FUNGOS MICOTOXIGÊNICOS. INTRODUÇÃOMicotoxinas são metabólitos secundários, tóxicos, produzidos por várias espécies de fungos. Esses microrganismos, sob condições favoráveis, podem se desenvolver sobre diversos substratos (entre os quais os alimentos) e produzir toxinas. Tal fato representa problemas para a saúde pública, uma vez que podem atingir o ser humano pelo consumo do alimento contaminado, ou pelo consumo de outros organismos que as tenham ingerido (ROEBUCH e MAXUILENKO, 1994; GALVANO, 2001; BAPTISTA et al., 2002).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
