Utilization of simulated flue gas for cultivation of Scenedesmus dimorphus

- Scenedesmus dimorphus showed excellent tolerance to high CO2 (2-20%) and NO concentrations (150-500 ppm).
- The maximum SO2 concentration S. dimorphus could tolerant was 100 ppm.
- The extremely low pH as well as the accumulation of bisulfite caused by SO2 inhibited algae growth.
- By neutralization with CaCO3, S. dimorphus could grow well on flue gas.
- The toxicity of flue gas could be overcome by intermittent sparging and CO2 utilization efficiency was enhanced.
