报告了使用物理诱变剂 (紫外线 )和化学诱变剂 (亚硝基胍 )对康宁木霉进行诱变处理时 ,环境物理因素对微生物致死率的影响。实验表明 ,当诱变剂的剂量或作用时间增加时 (包括物理和化学诱变剂 ) ,微生物的致死率会明显上升 ;微生物经过物理或化学诱变剂的处理后 ,再将其放入非自然环境中培养 (包括在电磁场中处理 ;在屏蔽室中处理及在高γ本底辐射的情况下处理 ) ,其致死率会有所变化 ;在诱变时采用多种诱变剂 ,及在孢子悬液中添加微量元素和限量培养液是提高微生物致死率的另一种方法。
The effect of environmental and physical factors on microbial lethality was reported when Trichoderma koningii was mutagenized using a physical mutagen (UV) and a chemical mutagen (nitrosoguanidine). Experiments show that when the mutagen dose or duration of action increases (including physical and chemical mutagens), the lethality of microorganisms will be significantly increased; after the treatment of microorganisms by physical or chemical mutagens, and then into the non- The lethality varies with the culture in the natural environment (including treatment in an electromagnetic field; treatment in a shielded room and treatment at high γ background radiation); the use of various mutagens in mutagenesis; and Spore suspension added trace elements and limited culture medium is to increase the lethality of microbial another method.
