Effect of sulphur compounds on cultivation process of microalgae chlorella vulgaris
The article deals with the investigation of the influence of sulfur compounds concentration on the cultivation of microalgae Chlorella vulgaris for the purpose of future use of flue gases as a nutrient source. The alteration of culture medium pH and microalgae biomass production under simultaneous injection of CO2 and H2SO4 or Na2SO3 are studied. It is shown that the enhancement of sulphur concentration to 0.44 g/L by using Na2SO3 increases the biomass growth by 15 percent and does not cause deviations from the optimal pH range.
