| Aflatoxins are hepatotoxic metabolites produced by Aspergillus flavus and A. parasiticus on a number of agricultural commodities. This research was carried out to evaluate the ability of thermolysed and active Saccharomyces cerevisiae to attenuate liver damage caused by aflatoxin. Diets were prepared containing 0 aflatoxin; 400 mug kg-1 aflatoxin; 400 mug kg-1 aflatoxin plus 1% of dehydrated active yeast, and 400 mug kg-1 aflatoxin plus 1% of thermolysed yeast. A bioassay with Wistar rats was conducted for 28 days, and body organs were weighted and analyses of the liver tissue of the animals were performed. The relative weight of heart, kidneys and liver from animals submitted to the different treatments did not show any difference, and liver tissue of... |

| Yeasts were applied to corn grains, containing 16 or 20% moisture, at concentrations of 1 and 2%. The cellular viability was assayed at 0, 15, 30, 90 and 110 days. The cellular viability did not differ statistically among the treatments up to 30 days of storage, with the median viability of 89.10%. The average viability found at 90 days (72.20%) was lower than in the first three storage periods. After 110 days, the average viability was 61.14%. In conclusion, since yeast cells were viable up to 110 days in storage on corn grains, these can be used as a vehicle for the application of yeast as a probiotic. |
