Controlling microbial growth in regenerative life support systems for closed environment in space is necessary to protect the health of the crew. The microbial control is one of key technologies of water recycling system for closed environment. The study of water recycle system for closed environment is being continued steadily also in our laboratory.
In this paper, the author carried out the experimental study as follows: (1) In order to provide the burden of microbe in waste water model, experiments holding rodents in closed environment for a month were performed. (2) Ozone disinfection was chosen as the subject of the study to evaluate applicability of use for water recycle system for closed environment, then microbe ozone sensitivity tests were performed.
The result, microbial species from experiment system include heterotrophs isolated from water and soil was obtained. Then, basic properties of ozone disinfection to accommodate water recycle system for closed environment were obtained.
