摘　　要： 对实验室保藏的一株高产Monacolin K红曲霉菌株的生理特性进行了研究，结果表明，该菌株菌落较小，成橙红色；菌丝有横隔，分生抱子着生于菌丝体或分支末端；最适生长温度为30～33℃；能耐8％浓度的乙醇；可以利用包括鼠李糖、松三糖、甘露醇等在内的17种碳源，但只能对葡萄糖、麦芽糖、蔗糖、糊精和乙醇等少数几种碳源进行发酵产气；在利用不同类型的氮源时发酵液色泽差异较大，其中对铵盐的利用较好。 Physiological characteristics of a Monascus with high-production of Monacolin K were investigated. Results showed that the size of this strain＇s colony was much smaller than the wild strain, and its color was orange red; and its conidia grown on the end of the hypha or branch. The optimum growing temperature was between 30-33℃. And it could tolerate 8% ethanol at least. It could utilize more than 17 different carbon sources, while it could just ferment few of them which including glucose, maltose, sucrose, et al. The color of culture liquid changed distinctly according to different nitrogen sources. Ammonium as a nitrogen source was easier than the nitrate to be utilized.
