Effect of Aeration on Growth and Aflatoxin Production by Aspergillus flavus in Submerged Culture

Hayes, A. Wallace
RESUMO
Aspergillus flavus ATCC 15517 produced up to 212 mg per liter of total aflatoxin in submerged culture in aerated (3,000, 6,000, 9,000, and 12,000 ml/min) and agitated medium in 14-liter fermentors with 10 liters of medium consisting of 2% yeast extract and 10% sucrose. Aflatoxin production increased with time. A maximum of 212 mg/liter was produced at 9,000 ml/min aeration, whereas the yield decreased substantially at the lower aeration rates. Two other strains of A. flavus synthesized aflatoxin in smaller quantities.
