Non-toxigenic strain of Aspergillus oryzae and Aspergillus sojae for biocontrol of toxigenic fungi

摘要

Non-toxigenic strains of Aspergillus such as from the species Aspirgillus oryzae and Aspergillus sojae are useful fungal biocontrol agents for preventing toxin contamination in agricultural commodities, especially those for human consumption such as peanuts and corn. These strains do not produce aflatoxin, any bis-furan ring-containing intermediates of the aflatoxin biosynthetic pathway and cyclopiazonic acid. They are also useful for controlling toxin damage to crops such as cotton. The strains include Aspergillus strains NRRL 21368, NRRL 21369, NRRL 21882, NRRL 30038, NRRL 30039 and mixtures thereof.
