Physiological activity of Chlorella following exposure to space flight factors aboard the orbital station "Saliut"]

The photosynthetic activity of Chlorella vulgaris str. LARG-1 was studied after its dark exposure in the Tamiya medium to space flight factors enboard the Salyut orbital station. The exposure of Chlorella cells in the inactive state did not influence their basic physiological parameters (rate of growth and reproduction, cell size and population structure, chlorophyll content, cell viability) during subsequent intensive cultivation. These results show the possibility of storing the generative material of unicellular algae under the experimental conditions.
