Effect of CO2 concentration on algal growth: A review

Natural changes in climate due to internal as well as external factors, like anthropogenic emission, fossil fuel combustion, transportation and heating which cause CO2 emissions is one of the major issues which causes global warming (increasing concentrations of greenhouse gases). The production of algae is identified as one of the solutions of carbon sequestration along with production of renewable fuel solving the problem of food crisis to a certain extent. This review paper summarizes how CO2 levels affected micro algal species. Several species of algae as Scenedesmus obliquus, Botryococcus braunii, Chlorella vulgaris, Nannochloropsis oculata have been reported to accumulate high concentration of lipid. These species are suitable for biofuel production as well as Carbon fixation.
