Flue gas compounds and microalgae:(Bio-) chemical interactions leading to biotechnological opportunities

Abstract:

Flue gases are a resource yet to be fully utilised in microalgal biotechnology, not only to moderate the anthropogenic effects on our climate, but also to steer microalgal resource management towards innovative applications of microalgal biomass compounds. These gases, both untreated and treated into current discharge standards, contain CO2, N2, H2O, O2, NOx, SOx, CxHy, CO, particulate matter, halogen acids and heavy metals. To better steer and engineer flue gas-fed microalgal cultures, all these compounds need to be considered. Therefore, here, we review (i) the chemical composition and treatment technologies of flue gas, (ii) the uptake pathways and removal of the different compounds in microalgae reactors, and (iii) the tolerance and effects on microalgae of all flue gas compounds. By emphasising the interactions between microalgae and flue gas compounds, we envisage new pathways for microalgal …
