Abstract:

Microalgae can utilize the high\|dose CO2 in the flue gases, through which the biomass and oil content of microalgae were improved significantly and carbon emission was also reduced. However, the low solubility of carbon dioxide in water has been the bottleneck of high\|dose CO2 utilization by microalgae. This article addressed CO2 fertilizer coupled to microalgal photobioreactors, discussed particularly  the improvement and characteristic of two types of photobioreactors fed with high\|dose CO2, that is, liquid or attached cultivation photobioreactors, with focus on the CO2 mass transfer and utilization. To summarize, the features of two photobioreactors, capacities of microalgal utilization of high\|dose CO2, as well as CO2 mass transfer characteristics were compared and commented, which might help to the high density cultivating of microalgae.
