Abstract

To isolate zearalenone-producing strains from agricultural products in Youngnam districts, various samples such as rice(60), barley(52), soybean(45), peanut(33), corn(32), maeju(27), unhulled rice(UR, 40), unhulled barley(UB, 54), and soil(32) collected. From 375 samples, 302 Fusarium strains were isolated. The isolated strains were cultured for 14 days at $30^{\circ}C$ in rice medium, and then screened zearalenone-producing strains by TLC and HPLC. The result was that 29 isolates[rice(3), maeju(2), corn(1), barley(5), soil(4), peanut(3), soybean(4), U.B.(5), U.R.(2)] were screened as zearalenone-producing strains by TLC, while 19 isolates [rice(2), maeju(1), corn(1), barley(4), soil(3), soybean(2), U.B.(3), U.R.(3)] by HPLC method.
