Effect of CO2 Aeration on Cultivation of Microalgae in Luminescent Photobioreactors
Scientists from UK performed an experiment to investigate the influence of CO2 aeration on microalgae biomass production, carbon dioxide fixation rate under a range of luminescence modified lighting
conditions. Two different algal strains Chlorella vulgaris and Gloeothece membranacea were taken for the experiment.
Results showed that the combination of blue light and 15% CO2 induced higher rates of lipid accumulation in both the strains. Aeration with 15% CO2 enhanced lipid production of G. membranacea, to at least twice the amount produced at 5% CO2 in all photobioreactors.
