Gas Revitalization by Microalgae

I. Studies on Species and Culture Condition

Abstract

Microalgae are a promising organism for bioregenerative gas revitalization, because of their high efficiency of light energy utilization and flexibility for fluctuation of CO₂ load.
Comparison of species of microalgae and effects of culture conditions on proliferation were studied to determine conditions for photo-bioreactor experiment. Germ-free strains of Spirulina platensis were chosen as promising candidates on the ground of proliferation rate, biomass composition and less possibility of interference of contaminated bacteria. Although the SOT medium resulted generally in sufficient proliferation rate and biomass concentration, proper concentration of sodium bicarbonate varied depending on luminous intensity.
