Aflatoxins (AFs) are secondary metabolites produced mainly by Aspergillus flavus and A. parasiticus. There are four types of AFs. The presence of AFs in feeds causes significant economic losses and serious health problems. In fact, AFB1 is one of the most potent natural liver carcinogens known. Lactic acid (LAB) has been widely studied to be applied in biopreservation. The inhibition action of LAB is based in the both competition against other microorganisms and production of various antimicrobial compounds such as lactic acid, diacetyl, acetaldehyde, acetic acid and bacteriocins. To study fungal and lactic flora and to evaluate the effect of LAB on A. flavus and A. parasiticus AFs producing isolated from brewers grain for swine feed.
