Current Concepts and Future Directions of CELSS [PDF]

open access: yes, 1985
Bioregenerative life support systems for use in space were studied. Concepts of such systems include the use of higher plants and/or microalgae as sources of food, potable water and oxygen, and as sinks for carbon dioxide and metabolic wastes.
