Microalgae and Photo Bioreactors: the Future Linked to CO2 Capture

Abstract

Pasquale Gabriele

Carbon dioxide (CO2) emissions are the main issue underlying climate change and are harmful to human health. To reduce this concentration, the use of microalgae has been experimented. Microalgae are the most important microorganisms in aquatic ecosystems for the global carbon budget they are essential for the capture and bioconversion of carbon dioxide (CO2 ) into energy. The microalgae come grown in photo bioreactors, closed and open systems that allow microalgae to grow and absorb CO2 . Another widely used type of photo bioreactor is the membrane photo bioreactor (MPBR). An important future development related to photo bioreactors and microalgae could be to merge the two types of systems, open and closed, managing to minimize system costs and allow scale cultivation industrial.
