内容記述 | A Controlled Ecological Life Support System (CELSS) is essential for habitation in extreme environments (space, polar regions, ocean depths, etc.) and an enormous amount of freshwater is used and regenerated for drinking and living. In order to assure human health, microbiological quality control of freshwater used in CELSS is required, and bacterial population dynamics in the system should be determined rapidly and accurately. In this study, bacterial abundance and the numbers of bacteria with physiological activity in freshwater used and regenerated in Closed Ecology Experiment Facilities (CEEF; Aomori, Japan) during the Closed Habitation Experiments were determined to understand bacterial abundance and activity in a closed habitation. The numbers of total bacteria and esterase-active bacteria in each sample were determined by fluorescent staining techniques. Colony-forming units were determined by the plate-counting technique and growing cells were also counted by the microcolony method. Our results suggest that bacterial numbers and their activities in freshwater used in CELSS could be accurately determined within a few hours by fluorescent vital staining. Rapid microbiological methods would contribute to the technical progress in the quality assurance of freshwater used in CELSS. For further simple and automated microbiological monitoring, we developed a simplified microfluidic device for quantification of bacteria in potable water. Comparisons of counts of Escherichia coli by the microfluidic system and by fluorescence microscopy closely correlated (r (exp 2) = 0.99). Bacteria in natural mineral water and in purified household tap water were accurately enumerated by using this system within 15 min after fluorescent staining. | |||||
