Abstract

The inoculation of S. lactis in a mixed culture with Aspergillus parasiticus and into a 3-day-old Aspergillus parasiticus culture reduced aflatoxin accumulation from 108.33 to 94.18 and 31.02 µg/ml, respectively, after two days of incubation. When S. laclis was cultured for 3 days before the inoculation of A. parasiticus spores, it was found that A. parasiticus could produce only 58.01 µg/ml of aflatoxin on day 2. S. lactis was further examined for the ability to detoxify aflatoxin B1 in yoghurt in comparison with lactic acid bacteria from commercial yoghurt. The result showed that S. lactis could detoxify aflatoxin B1 from 50 to 33.70 µg/ml whereas bacteria from commercial yoghurt detoxified in B1 from 50 to 37.25 µg/ml after 7 days of storage
