Abstract
The research aims to develop Chlorella sp. cultivation using a carbon dioxide concentration control system including to investigate the cultivation system of Chlorella sp. effecting on the growth rate. The cultivation system could control a pH range of cultivation between 6.7 and 6.9 leading to be appropriate with Chlorella sp.’s growth. In addition, the carbon dioxide concentration in water of cultivation correlates with acidity. Therefore, pH value in the cultivation system is regulated by filling the carbon dioxide concentration or the neutral water. The experimental result shows that the Chlorella sp. cultivation for the procedure, using the carbon dioxide concentration control system improving a pH value every 10 minutes, displays the 2.3 times of algal number density at last range of exponential phase. The algal number density under open-system is 1,015 × 103 cells/mL increasing to 2,322.5 × 103 cells/mL under the control system. In addition, an average growth rate increases to 1.7 times. The average growth rate under open-system is 195 × 103 cells/mL/day increasing to 333.47 × 103 cells/mL/day under the control system. Moreover, the cultivation with the carbon dioxide concentration control system could expand the range of growth in exponential phase explaining the appropriate environment for the Chlorella sp. cultivation.
