Abstract

Summary: The optimum levels of sucrose, (NH)SO, MgSO, KHPO and ZnSO for aflatoxin production in a chemically defined medium have been established. The last two were found to be essential for fungal growth and aflatoxin production. The effect of various carbon sources on aflatoxin production was tested using the defined medium. Asparagine was found to be essential for aflatoxin production. Very little aflatoxin was produced in the absence of asparagine with any of the other inorganic nitrogen sources tested. Supplementation with yeast extract, Casamino acids, Casitone and peptone increased the aflatoxin yield, but omission of asparagine led to decreased aflatoxin yields even when complex nitrogen sources were present. Asparagine could be replaced by aspartic acid or alanine.
