One 40-g male albino mouse was kept in good health for 66 days in a chamber containing an algal photosynthetic gas exchanger. Carbon dioxide was well controlled, oxygen was slowly increased, and nitrogen was decreased in the chamber. Photosynthesis can support life in a hostile environment for extended periods of time.
