Abstract

Aflatoxin is known to be highly carcinogenic polyketide metabolites. Saccharomyces cerevisiae are known to bind to these toxins and help in decontamination.Yeasts other than Saccharomyces predominate in most of the fermented foods. However their binding capacities to these toxins are not known. On screening 3 promising isolates which had high binding affinity were observed. The bound toxins were characterised through LC-MS which indicated the formation of sodium adducts. The isolates were identified as Pichia anomala, Clavispora lusitaniae and Candida tropicalis. Among these strains Candida tropicalis was found to be efficient in aflatoxin binding. These forms are common residents of most of the fermented foods, which pave a new way for the decontamination of aflatoxin.
