Abstract
The characteristics of CO2 fixation by Chlorella HA-1 cultured in bubble columns were studied to achieve high photosynthetic rates per basal area. The influence of experimental conditions such as the diameter of a bubble column and gas flow rate, on photosynthesis of Chlorella HA-1 was investigated. The maximum productivity and the overall CO2 fixation rate obtained in a 0.15 L bubble column was 1.09 g dry biomass/L-day and 1048 g CO2/m2-day, respectively. Light limitation has been observed in the bubble columns having a diameter larger than 3.5 cm. As the reactor volume increased, the decrease of the CO2 fixation rate was remarkable. High gas flow rate was helpful to mitigate the light limitation problem.
