Influence of lipids with and without other cottonseed reserve materials on aflatoxin B1 production by Aspergillus flavus.

Fungal utilisation of three major cottonseed reserve materials, raffinose, triglycerides (refined cottonseed oil) and cottonseed storage protein, was monitored in vitro over a 7 day fermentation period. A. flavus rapidly converted raffinose to fruetose and melibiose and then hydrolysed the melibiose. These simple sugars apparently supported initial growth and AFB1 production. Raffinose and melibiose were nearly exhausted by day 2. Fungal hydroly sis of triglycerides began as exhaustion of carbohydrate approached. After day 2, rapid catabolism of the released fatty acids began and coincided with glucose regeneration through gluconeogenesis, which peaked on day 6. The fungus did not preferentially utilise specific fatty acids.
