Aflatoxin B1 production by Aspergillus flavus (NRRL 6432) was determined on physically damaged corn stored at 35,25 and 20°C and at relative humidities of 97 and 92%. Production at lower relative humidities of 80 and 85% were also tested at 25°C. Production lag times were significantly different for all test conditions. Lag times ranged from 46 h at 97% relative humidity and 35°C to 173. 8 h at 20°C and 92% relative humidity. Aflatoxin B, concentration doubled every 6 to 10 hours after a level of 10 ppb had been reached. Production rate constants were not significantly different between …
