摘要：

Culturing of Aspergillus flavus was conducted in static flask cultures and 4 in. × 5 ft columns (containing 7–8 kg corn) to measure the effects of moisture, temperature, and air flow upon growth and the production of aflatoxin. Aflatoxin levels as high as 6200 ppb (dry basis) in 10 days were observed. Conditions were selected (ca. 20% moisture, 0.008 liter air/kg corn/min air flow with 1.5 liter/kg/min recirculated) for production of aflatoxin in 1200 bushels of corn in a 18‐ft diam corrugated steel Butler storage bin for preparation of contaminated corn for animal feeding trials and for testing of an ammoniation process for decontamination of aflatoxin in corn. A target level of 1000 ppb aflatoxin was attained. Copyright © 1979 John Wiley & Sons, Inc.
