Survey and Control of the Occurrence of Mycotoxins from Post-harvest Fruits 1. Mycotoxins Produced by Pencillium Isolates from Apple Pear, Citrus and Grape

수확 후 과실류에 발생하는 진균독소의 탐색 및 방베 1. 사과, 배, 감귤, 포도에서 분리한 Penicillium이 생산하는 주요 진균독소

A total of 65 isolates of Penicillium were isolated from decayed post-harvest fruits of apple pear citrus and grape. The Penicillium species isolated from the apple were idnetified as P. aurantiogriseum and P. expansum those from the pear were P. crustosum and P. expansum and those from the grape were P. aurantiogriseum and P. expansum, From decayed citrus fruits. P. digitatum and P. italicum were isolated. Citrinin and patulin from these species in the YES(yeast extract sucrose) broth were extracted with ethyl acetate and purified by thin-layer chromatography(TLC) and high performance liquid chromatography(HPLC) Among 51 isolates of Penicillium from apple pear and grape 7 isolates produced citrinin 13 isolates produces patulin and 12 isolates produced citrinin and patulin also. All 14 isolates of Penicillium from citrus produced only patulin.
