空间环境对微生物的影响及应用

Effect of Space Environment on Microorganisms and its Applications

针对微生物对航天活动和空间生命科学研究的影响,介绍了国外研制的多种微生物空间搭载平台,综述了空间单一或复合环境因子对微生物的作用机制;指出微生物在处于复杂空间环境中时易形成遗传变异,同时由于所处环境因子不同,形成的遗传变异机理和水平也各不相同。最后对微生物的空间应用提出了展望。

Microorganisms can be used as the model systems for the space applications and the future space missions. In this paper,a large number of facilities developed for short- and long- term microbial exposure experiments were introduced. The basic biological mechanisms of microorganisms under space environmental factors（ solar extraterrestrial UV radiation,HZE particles and space vacuum） were compared and analyzed,and the biological effects of the different factors of space resulted in different genetic variations in microorganisms. Finally,the implications of the microbiological studies were discussed.
