title: Production of fumonisin B1 and B 2 byFusarium moniliforme isolated from Korean corn kerneis for feed.
abstract: The natural occurrence of fumonisin B1 (FB1) and B2 (FB2), a promoter for hepatocarcinogenesis, was investigated in Korean corn kernels for feed by HPLC with fluorescence detection. From the 12 corn kernel samples, FB1 was detected in 5 samples at levels ranging from 53 to 1327ng/g, while FB2 was found in 4 samples from 69 to 680ng/g. In the positive samples, the average concentrations of FB1 and FB2 were 506 and 288ng/g, respectively. One sample (No. K3) showed the highest FB1 and FB2 contents as 1327 and 680ng/g, respectively.In the micrological survey on 5 positive samples for FB1 and FB2, 6 strains ofFusarium monlliforme were isolated, and all these isolates had a producibility of FB1 and FB1, with maximum levels of 80.7 to 180.9 g/g.Thisis the first report on the natural co-contamination of FB1 and FB2 in Korean corn kernels for feed, and on the ability ofF. moniliforme isolated from corn kernels for feed in Korea to produce FB1 and FB2.
