Effect of nutritional factors on aflatoxin B1 inhibition of growth in Escherichia coli and Salmonella typhi.
The extent of growth inhibition by aflatoxin B1 in S. typhi and E. coli was greater in the presence of sodium citrate or sodium phosphate, palmitic and stearic acid than aflatoxin B1 alone. The addition of amino acids (glycine or glutamic acid) stimulated growth in E. coli and inhibited in S. typhi in the presence of aflatoxin B1. Other nutrients, such as yeast extract, lactose, or salt addition did not alter aflatoxin B1 antibacterial activity but decreased growth was observed in the presence of peptone.
