Kinetic model for effects of simulated flue gas onto growth profiles of Chlorella sp. AE10 and Chlorella sp. Cv

In this study, the effects of different concentrations of the simulated flue gas onto algal growth and photosynthetic activity were evaluated for bothChlorella sp. AE10 andChlorella sp. Cv. The growth profiles were correlated by a simple kinetic model. It was indicated that the simulated flue gas led to low pH and the photosynthetic activity was partially destroyed.Chlorella sp. Cv can tolerate full simulated flue gas, 10% CO2 + 200 ppm NOx + 100 ppm SOx. The pH in medium maintained at 6 and the photosynthetic activity was more than 0.6 at the first 6 days. If the concentration of NOx was more 100  ppm and that of SOx was more than 50  ppm, the pH was declined to 4 at day 2 or 3 forChlorella sp. AE10. At the same time, the related photosynthetic activities ofChlorella sp. AE10 were less than 0.4, which was not suitable for algal growth. It was shown thatChlorella sp. Cv could be used for CO2 fixation from the simulated flue gas.
