While photosynthetic microorganisms offer a promising route to generate sustainable transportation fuels and products using solar energy, boosting their photosynthetic efficiency above normal levels (<5%) will help ensure its economic viability. A major source of inefficiency is that photosynthetically active radiation (PAR, 400-700 nm) constitutes...

Microalgae are very useful biological systems for capturing carbon dioxide (CO2 ) and generating biomass and many useful products. Increasing the CO2 concentration in gas supplied to a microalgae growth system can improve its productivity many fold over using atmospheric air. Flue gas could be a good source of CO2 -enriched gas; however, its usefulness...
