Variations in levels of adenine nucleotides during growth of A. parusiticus were studied under asparagine and zinc deficiency and correlated with aflatoxin biosynthesis. ATP levels decreased gradually from exponential to stationary phase but the reverse was true for ADP and AMP. However, AMP levels in stationary phase were virtually constant under all growth conditions employed. Increased AMP levels were observed in fungal mycelium on high aflatoxin‐producing medium as compared to the deficient media. The onset of aflatoxin biosynthesis however was accompanied by a lowering of energy charge and ATP levels.
