Effect of CO2 Supply Condition on Microalgal Growth in a Bubble Column Photobioreactor |
초록 |
Recently, microalgae have been considered as an important feedstock for the production of biofuels. The cost of CO2 in large-scale algal culture is of prime importance to the total economics. The necessity to have huge amounts of CO2 readily available enforces the use of flue gases as carbon source. However, some microalgae cannot use flue gas directly, because power plant flue gas contains a higher concentration of CO2. In this study, we focused on finding the conditions for the microalgae to grow without growth retardation under high CO2 partial pressure. As a result, the ratio of HCO3- supply rate to HCO3- consumption rate determined culture pH and the microaglae showed similar specific growth rate of 0.98 day-1 within adequate pH levels regardless of CO2 partial pressure. This study provide strategy for using flue gas directly at microalgae culture by adjusting the ratio of HCO3- supply rate to HCO3- consumption rate. |
