閉鎖生態系―宇宙農業におけるナトリウムとカリウムの循環―

抄録

Sodium and potassium separation is studied for a part of closed ecological life support system (CELSS) and space agriculture program. The purpose of the system is to establish recycle of minerals between man and higher plants in closed system. By physiological reasons, man takes a greater amount of sodium compared with that contained in plants. For regenerative production of foods by the use of higher plants, it is necessary to remove excess sodium from human wastes. Several kinds of physicochemical and biological methods are discussed to examine their feasibility in this application.
