Production of aflatoxin B1 and G1 by Aspergillus parasiticus on silica gels.
Silica gels were prepared by acidifying alkaline silicate solutions with phosphoric or tartaric acid. Various combinations of glucose, sucrose, yeast extract, and salts were included in the gels an nutrients. Maximum production of aflatoxins B1 and G1 occurred when silica gel (0.4 to 0.5 cm deep in a petri dish) containing 20% sucrose and 2% yeast extract, and gelled with tartaric acid, was inoculated with approximately 120 to 12000 spores of Aspergillus parasiticus per plate; and plates were incubated at 28 degrees C for 10 days.
