An indispensable condition for the accomplishment of long flights by man in outer space is the creation of systems of regeneration of the air, based on the process of the photosynthesis of green plants. Such a system of regeneration as a whole represents a quite intricate complex of equipment the control of which should be effected automatically. The object of the automatic control in this system is the culture of one or several green plants, which in the process of photosynthesis accomplish the absorption from the air of the cabin the dioxide and the liberation of gaseous oxygen. At the present time it is considered as very probable that the plants to be used for this purpose would be single-celled algae, preferably different kinds of chlorella. The analysis of the rich experimental material devoted to the research of the process of photosynthesis of chlorella indicates, however, that for sufficiently full characterization of the culture of single-celled algae as the object of automatic control it is necessary to carry on a series of supplemental biological experiments, the makeup and specific nature of which cannot be clearly defined without making clear the problems and methods of automatic control of the culture.
