Abstract

フランスの堆肥から分離された不完全菌<i>Spicellum roseum</i>のタイプ由来株を培養すると,トリコテセン系マイコトキシンを産生することが知られている.桃色かび立枯病を引き起こす原因菌として,我々は長野県のエノキタケ(<i>Flammulina velutipes</i>)から数株の<i>S. roseum</i>を分離した.これら日本産の<i>S. roseum</i>がトリコテセン系マイコトキシンを産生するか否かを調べるために,分離菌株を米培地で培養し,マイコトキシンの分析を行った.EIモード及びCIモードのガスクロマトグラフ質量分析計で8-デオキシートリコテシンを検出し,確認した.しかしながら,赤かび病罹病のムギから検出されるトリコテセン系マイコトキシンとして有名なデオキシニバレノール,3-アセチルーデオキシニバレノール,フザレノン-X及びニバレノールは検出されなかった.

Ex-type culture of <i>Spicellum roseum</i> isolated from silage in France has been known to produce some trichothecenes. As the causative agent of the pink mold damping-off disease, we isolated some strains of <i>S. roseum</i> from a cultivated mushroom <i>Flammulina velutipes</i> at Nagano, Japan. To examine whether the Japanese strains of <i>S. roseum</i> produce trichothecenes or not, the isolates were cultivated on rice medium and extraction was made for mycotoxin analysis. 8-Deoxy-trichothecin was accordingly detected and confirmed with GC/MS by means of EI and CI mode. However, deoxynivalenol, 3-acetyldeoxynivalenol, fusarenon-X and nivalenol were not detected in the extract, all of which are well known to be detected from scabby wheat.
