Abstract

BACKGROUND: Yeasts are microorganisms that have the ability to absorb aflatoxins.OBJECTIVES: The effect of the yeast Saccharomyces cerevisiae (PTCC 5177) on aflatoxin B1 DETOXIFICATION and absorption of toxin in in vitro (the cow rumen) was investigated.METHODS: For this purpose, the yeast used in various treatments (live-treated, autoclave, heat-treated, treated with acid 100oC) was prepared and added to the rumen of cattle. Aflatoxin B1 in different doses (0, 5, 10, 20) ppb in the rumen were added and were incubated at 37oC for one and two hours. The amount of toxin residues was measured by ELISA using Europroxima kits.RESULTS: The results showed that microorganisms that have been treated in an autoclave have the highest amount of toxin removal (90.5%) (p<0.05). Also, with increases in the incubation time, the amount of toxin absorbed significantly increased (78%) (p<0.05) and with increasing concentrations of toxin in vitro the yeast’s ability to absorb toxin increases. These results demonstrate that the major toxin is absorbed by the yeast cell wall and therefore non-living microorganisms shown an ability to absorb higher.This is because the composition of the yeast cell wall mannoprotein that are effective at absorb in toxin.CONCLUSIONS: As a strategy for the animal feed industry the use of glycomannan yeast cell wall can be useful for reducing aflatoxin B1.
