n essentials, the microalgae
essentially biologically fix and store CO2 via photosynthesis, which
can convert water and CO2 into organic compounds without secondary pollution. Microalgal-CO2 fixation features potential advantages over other carbon capture and storage approaches, such as
a wide distribution, high photosynthesis rate, good environmental
adaptability and easy operability. Additionally, the microalgal
biomass can be harvested after CO2 fixation to produce microalgal
biofuel that can be utilized as a renewable or sustainable energy
source (Fig. 1).
