AbstractLactobacillus rhamnosus GG and Lactobacillus rhamnosus LC-705, previously shown to effectively bind to aflatoxin B1, were subjected to various chemical and physical treatments to examine the effects of these treatments on the binding affinity of these strains towards aflatoxin B1. Treatment of bacterial pellets of both strains with hydrochloric acid significantly (P < 0.05) enhanced the binding ability when compared to nontreated pellets or pellets treated by other methods. An enhancement of bacterial ability to bind aflatoxin B1 was also observed when the bacterial pellets were subjected to heat treatment by either autoclaving or boiling at 100°C in a water bath, but the impact of these two treatments was not as effective as the acid treatment. Ethanol, UV radiation, sonication, alkaline, or pH treatments either had no effect or reduced the binding ability of the bacteria.
