| 摘 要： | 目的]诱变选育耐酒精木糖酒精的发酵菌种。方法]以嗜单宁管囊酵母菌株g-13为出发菌株，筛选出1株耐酒精浓度高、发酵性能优良的发酵木糖产生酒精的嗜单宁管囊酵母菌株m-8，将其在紫外灯功率为15w，照射距离为30cm，照射时间为120S的条件下进行紫外线诱变。结果]经过大量筛选得到优良菌株L—16，在适宜条件下经过发酵其酒精浓度可达7．77g/L，较出发菌株酒精浓度提高了12％。结论]选育出了1株优良的耐酒精木糖发酵菌种，为开发纤维素类可再生资源提供科学依据.

| Abstract: | Objective] The research aimed to use ultraviolet mutagenesis to breed bearable ethanol strains with ethanol fermentation from xylose.Method] From the Pachysolen tannophilus strain g-13,through separation,selection,domestication and cultivation,an excellent Pachysolen tannophilus strain m-8 was obtained,which could ferment xylose to ethanol.Then it was bred by ultraviolet mutagenesis under the conditions of ultraviolet lamp 15 W,raying distance 30 cm and raying time 120 s.Result] One mutant L-16 was obtai... |
