Algae-Mediated Carbon Dioxide Sequestration for Climate Change Mitigation and Conversion to Value-Added Products - Biotechnological Applications of Microalgae - page 173

microalgae tolerating high CO 2 concentrations can be isolated from relevant sources
such as lakes, ponds, etc. near thermal power plants. The microalgal strains that can
tolerate high CO 2 concentrations and also synthesize food/feed and biofuel precur-
sors need to be developed by exploring the microbial diversity. It should be possible
to control the composition of food and biofuel precursors by suitably manipulating
stress conditions such as light, temperature, and nutrients. The high performance of
cultivation systems (open-pond and/or closed photobioreactor system) for microal-
gae with high biomass productivity and energy efficiency should possibly be devel-
oped through a fundamental understanding of culture behavior as well as gas-liquid
mass transfer, reactor hydrodynamics, shear stress profiles, light penetration, pho-
toperiod, etc.
Therefore, future research in this area is required to provide new insights into
novel ways to use microalgae in economically viable value-added production
processes along with their integration with CO 2 sequestration.
