B When man goes to space, inevitably microbes hitchhike Some of these microbes are needed ( for the human body, for water purification, food production, ), others are unwanted ( pathogens, food spoilage, etc) To assure the safety and well -being of the astronauts in their closed and isolated space habitat these microbes have to be monitored and Therefore it is required to understand how earthly bacteria acclimate on the short term and adapt over the long term to space A The aim of this work is to investigate how bacteria respond and behave in space flight This is done through experiments in the International Space Station during short space missions ( MESSAGE 1 & 2 experiments, MOBILISATSIA experiment) and experiments on ground mimicking space radiation and microgravity The environmental bacteria Cupriavidus metallidurans CH34, Rhospirillum rubrum S1H, Eschericia coli, Pseudomonas aeruginosa PAO1 and Bacillus cereus have been sel ected as test 翻译:背景。当男人去太空,不可避免的微生物搭便车。其中的一些 细菌是必要的(如对于人体,对水质净化、粮食生产,等等。) 其他人是不必要的(如病原体、食品腐坏等等)。确保安全及-being 宇航员在其封闭的空间,这些微生物栖息地和孤立的 监视和控制。因此必须了解地球细菌 适应环境相适应的短期和长期的太空飞行。 目的。这个工作的目的是探讨如何应对和细菌表现在太空飞行 条件。这是通过实验,在国际空间站,在短暂的 太空任务(例如。要旨1和2个实验中,MOBILISATSIA试验)和实验模拟空间辐射地面和微重力环境。Cupriavidus metallidurans CH34环境细菌,Rhospirillum石S1H Eschericia、大肠杆菌、绿脓杆菌PAO1和芽胞杆菌已经被作为测试生物摘录。
