摘要
以毛霉Ｍ２６３为出发菌株，经紫外线、γ－射线及高温处理复合诱变，并采用高温培养条件定向驯化，获得１株耐高温毛霉菌株Ｍ２６３－３．该菌株在３２℃条件下，生长正常，酿制的腐乳质量优良；进行了培养基及产酶条件试验，选出了最佳培养基及适宜的培养条件。
A high-temperature resistant strein M263-3 was obtained from the mutiple mu-tants of Mucor M263 treated with ultraviolet ray,γ-ray and high temperature when the muti-ple mutants were bred under the condition of high temperature. The strain can regularly growat 32℃ and produce good quality bean curd milk.The best nutrient medium and proper cul-ture conditions for M263-3 were selected by test of proteinase activity.
