Research Note: Inhibition of Alfatoxin-Producing Fungi by Welsh Onion Extracts

摘要

Welsh onion ethanol extracts were tested for their inhibitory activity against the growth and aflatoxin production of Aspergillus flavus and A. parasiticus. The survival of spores of A. flavus and A. parasiticus depended on both the extract Concentration and the exposure time of the spores to the Welsh onion extracts. The mycelial growth of two tested fungi cultured On yeast extract-sucrose broth was completely inhibited in the presence of the Welsh onion ethanol extract at a concentration Of 10 mg/ml during 30 days of incubation at 25 deg. C.
