英文摘要	culture conditions are very important to co(2) bio-fixation and carbohydrate accumulation in microalgae. the objective of this study was to optimize semi-continuous culture conditions of tetraselmis subcordiformis in a rectangular airlift photobioreactor for obtaining maximized carbon dioxide fixation rate and intracellular starch productivity. the effects of the initial biomass concentration (0.13, 0.8, 1.8, 2.8 and 3.47 g l(-1)), the gas flow rate (0.03, 0.1, 0.2, 0.3 and 0.37 v v(-1) m(-1)) and different carbon dioxide concentrations (1.63, 5, 10, 15 and 18.37%) were considered using a central composite design. by using response surface methodology and the desirability function approach, the optimal co(2) fixation rate of 55.15 mg l(-1) h(-1) and the intracellular starch productivity of 10.66 mg l(-1) h(-1) occurred when the initial biomass concentration was 1120 mg l(-1) and the air supplemental co(2) concentration was 6.9% with a gas flow rate of 0.35 v v(-1) m(-1). these results suggest the potential of applying t. subcordiform to co(2) mitigation and starch production.
