Sequestration of CO2 in a photobioreactor using freshwater green microalgae

Abstract: Microalgae are aquatic plants that are able to capture carbon dioxide (CO2) during photosynthesis; a process where light is converted to chemical energy. The organisms that are capable of facilitating this process are referred to as photoautotrophs. Currently, the world is faced with a crisis of global warming due to the production of greenhouse gases (i.e. CO2) produced at various industries. The utilization of microalgae for the mitigation of CO2 emission is deemed as a sustainable solution since these microorganisms utilise CO2 as a carbon source and that the resultant microalgae biomass can be used to produce value-added products. A variety of bioreactor designs have been used to culture microalgae, however, closed photobioreactors (PBRs) are generally utilized since they minimize contamination and control parameters such as temperature, pH, and light intensity...M.Tech.
