A study on the isolation of aflatoxin-producing strains from agricultural products in Korea.
In order to isolate aflatoxin-producing strains from agricultural products in the Youngnam district of Korea, rice, barley, unhulled barley, corn, soybean, Meju (soybean paste), peanut, and soil samples were collected from markets or homes. From the 347 samples, 280 strains of Aspergillus spp. were isolated. As a result of screening by thin layer chromatography (TLC), 29 strains showed fluorescent spot and four strains had the same Rf values as those of standard aflatoxins. The percentage of contamination of aflatoxin-producing strains was 1.4%. The four strains were classified as the Aspergillus flavus group by the examination of characteristics and morphology.
