[Experiment with a physiologically active culture of Chlorella on "Soiuz-9" spacecraft]

A physiologically-active culture of chlorella was for the first time exhibited on board the "Soyuz-9" spacecraft. The use of a special four-socket container made it possible to investigate in one experiment the effect of the factors of a space flight on the cells of algae developing in illumination during 1, 6 and 14 days. Besides that the effect of the flight conditions was studied on the culture of chlorells. Insignificant change in sensitivity of the cells to the effect of the flight factors depending upon the duration of their exposure in the active condition is shown.
