Ability of dairy strains of lactic acid bacteria to bind a common food carcinogen, aflatoxin B1

This study was conducted to examine the ability of selected dairy strains of lactic acid bacteria to remove aflatoxin B1 (AFB1) from liquid media. Both Lactobacillus rhamnosus strain GG (LBGG) and L. rhamnosus strain LC-705 (LC705) can significantly (P > 0.05) remove AFB1 when compared with that by other strains of either Gram-positive or Gram-negative bacteria. Removal of AFB1 by LBGG and LC705 was a rapid process with approximately 80% AFB1 removed at 0 hr. Removal of AFB1 by these two strains was both temperature and bacterial concentration dependent.link_to_subscribed_fulltex
