The microalgae and cyanobacteria are capable of using free CO<sub>2</sub> and bicarbonate ions as a source of inorganic carbon during photosynthesis. In this study, CO<sub>2</sub> gas in range of 4-7% was captured selectively by a special equipment using a catalyst-adsorption system and stored for growing <em>Spirulina platensis</em> after effective removing the accompanied gases presented in the flue gas.</p> <p>The obtained research results indicated that the recuperated CO<sub>2</sub> content was proved to be good carbon source for growth of a Cyanobacterium <em>Spirulina platensis</em>. The growth of <em>Spirulina platensis</em> in the modified Zarrouk’s medium supplied with this CO<sub>2 </sub>source was highest while biomass quality of <em>Spirulina platensis</em> using CO<sub>2</sub> collected from the coal-firing process was almost equivalent to that of the Cyanobacterium grown in nutritive medium supplied with pure CO<sub>2</sub> source.</p> ER -
