Resumen
The environmental deterioration and global warming caused by anthropogenic carbon dioxide (CO2) emissions are major issues facing the scientific community nowadays. The development of processes devoted to the reduction of CO2 concentration in polluted gases is critical to ensure environmental sustainability, especially if processes allow the recovery of the carbon into bioproducts or bioenergy (biofixation). Among the microbial workhorses used for biofixation, microalgae present remarkable advantages: rapid growth rate, efficient capture of CO2 through gas/liquid exchange and production of valuable biomass. This chapter examines the current technologies available for microalgal production coupled to CO2 fixation that could slow down the actual trend in CO2 increase due emissions issued from different sources. An overview of the bioreactor configurations used for this purpose is presented along with the main figures of productivity and requirements. Case studies reported are reviewed. Finally, the biofixation capacity of main culture methods is analyzed quantifying the biological productivity of biomass and the emissions involved in the culture process.
