Abstract : The development of air regeneration systems utilizing photosynthesis of unicellular algae appears feasible due to efficiency of current bioengineering systems used for Chlorella cultivation and possibility of assuring stable performance of the systems. The efficiency of cultivation procedures used at present is achieved first of all by re-use of the culture medium without its intermediate treatment in adjacent components of the system. Stability of the system is related to biological peculiarities of the biological material (population involving specimens of different age and high reproduction rate) and can be maintained by certain techniques.
