| 摘 要： | 目的:诱变筛选阿魏菇多糖高产菌,探索食用菌的离子束和激光复合诱变育种方法。方法:尝试用阿魏菇菌丝单细胞为靶材,以离子束注入和激光辐照为复合诱变手段,采用营养缺陷型筛选办法定性初筛,摇瓶发酵定量复筛。结果:通过离子束注入诱变,获得了2株菌丝体多糖产量分别达到551.80mg/L和659.46mg/L、较1号出发菌株提高了46.5%和75.2%的多糖高产菌PFPH-1和PFPH-2;在此基础上,以激光辐照为复合诱变手段,获得了1株菌丝体多糖产量达到762.50 mg/L、较出发菌株PFPH-2提高了15.63%的多糖高产菌PFPH-3。结论:离子束和激光复合诱变育种方法在改良阿魏菇多糖高产性状方面诱变功效显著。
