微孢子虫孢子发芽机理 总被引:2,自引:0,他引:2
内部渗透压的升高是微孢子虫孢子发芽的直接驱动力,海藻糖酶催化海藻糖水解为葡萄糖或果糖是水生型微孢子虫孢子发芽的生化基础,PH值,离子种类及浓度、温度、射线等均能影响孢子发芽,陆栖型微孢子虫和水生型微孢子发芽过程中的糖代谢存在差异。 相似文献

Objective
Chlorine dioxide (CD) gas has been used as a fumigant in the disinfection of biosafety laboratories. In this study, some experiments were conducted to assess the inactivation of spores inoculated on six materials [stainless steel (SS), painted steel (PS), polyvinyl chlorid (PVC), polyurethane (PU), glass (GS), and cotton cloth (CC)] by CD gas. The main aims of the study were to determine the sporicidal efficacy of CD gas and the effect of prehumidification before decontamination on sporicidal efficacy. 相似文献3.
大球盖菇菌株形态学观察 总被引:1,自引:0,他引:1
从美国、波兰和中国收集了10株大球盖菇菌株。形态学观察表明,在PDA培养基上,菌落形态有绒状、毡状和絮状,有的有同心轮纹,有的有放射纹,有的菌丝生长旺盛、浓密、菌落平坦、圆形,有的则相反。用荧光染料双苯并咪唑Hoechst33258显微观察了大球盖菇菌丝体,结果发现所有菌株的菌丝细胞都含有双核,并且有明显的锁状联合结构,除St_4、St_5菌株有无性孢子外,其它均无无性孢子。 相似文献
