| This study was carried out to examine aflatoxin B1 (AFB1) removal ability of four strains of lactic acid bacteria (LAB). Three indigenous (Lactobacillus rhamnosus TMU094, Lactobacillus fermentum TMU121 and Pedioccus pentosaceus TMU457) and a non-indigenous (Labacillus rhamnosus PTCC1637) isolates were studied. The strains were incubated with (AFB1) at different time. The toxin residual in the supernatant was determined. Reduction of the toxin quantity was observed by all species. Binding of aflatoxin by the studied LAB varied from 19.41 to 75.06%. Aflatoxin-binding activity showed time dependent trend taking into consideration of different incubation periods. Lactobacillus rhamnosus TMU094 bound 25.64 to 75.06%, L. fermentum bound 38.63 to 72.15%, P. pentosaceus bound 24.86 to 63.21% and L. rhamnosus PTCC1637 bound 19.41 to 35% of AFB1 during the studied course of incubation times. These results showed that indigenous strains of LAB are able to bind AFB1 effectively | ||
