Abstract
In order to evaluate the safety of greenhouse horticultures, a large number sample sources were collected, and the fungi of Aspergillus sp. and Penicillium sp. were isolated from them. Indirect competitive ELISA method and high performance liquid chromatography (HPLC) were applied to confirm the ochratoxin A producing abilities of isolated strains. One hundred ninety two sample sources including soil, pepper, strawberry and water mellon were collected for fungi isolation from western Gyeongnam, Andong and Gyeongbok. One hundred forty two strains of Aspergillus sp. and one hundred fifty three strains of Penicillium sp. were isolated respectively from them. The isolated fungi were tested for the production of ochratoxin A by ELISA. After culture of them on the modified sucrose low salt medium at
시설 원예산물 중 곰팡이 독소 생성능이 있는 균주의 오염여부를 조사하기 위해 진주를 비롯한 서부 경남 일원과 경북 안동 근교에서 가지, 메론, 배추, 상추, 오이, 수박, 참외, 토마토, 딸기, 및 그 토양 등의 시료를 수집하여 ochratoxin A 생성균의 오염정도를 관찰하였다. 분석방법은 indirect competitive ELISA 법을 사용하였으며, HPLC법과도 비교 분석하였다. 그 결과 경남 일원과 경북 안동 근교에서 총 192점의 시료를 분리하여 균분리를 실시한 결과 Aspergillus속 142균주, Penicillium속 153균주를 분리하였다. 분리된 균은 SLS배지로
