Effect of Saccharomyces cerevisiae yeast on ruminal detoxification of aflatoxin B1

Yeasts are microorganisms that have the ability to absorb aflatoxins.
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.
For this purpose, the yeast used in various treatments (live-treated, autoclave, heat-treated, treated with acid 100 °C) 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 37°C for one and two hours. The amount of toxin residues was measured by ELISA using Europroxima kits.
The results showed that microorganisms that have been treated in an autoclave have the highest amount of toxin removal (90.5%) (p As a strategy for the animal feed industry the use of glycomannan yeast cell wall can be useful for reducing aflatoxin B1.
