Compared to conventional terrestrial crops they have a very fast growth rate and can be produced on non-arable land. During microalgae cultivation, carbon dioxide(CO_2) is supplied as the carbon source for photosynthesising microalgae. There are a number of potential CO_2 supplies including air, flue gas and purified CO_2. In addition, several strategies have been applied to the delivery of CO_2 to microalgae production systems, including directly bubbling CO_2-rich gas, microbubbles, porous membrane spargers and non-porous membrane contactors.
