The concentrations of chlorophyll a and b as well as chlorophyll a/b ratio of Dunaliella tertiolecta cultured outdoors under different sodium bicarbonate concentrations in ATCC-1174 DA medium using rotating floating photobioreactor. a The changes in chlorophyll a levels of D. tertiolecta under 0.02 mol L−1 NaHCO3 (filled red circle) and 0.10 mol L−1 NaHCO3 (filled blue triangle) as compared to the control, 0.00 mol L−1 NaHCO3 (filled black cube). b The changes in chlorophyll b levels of D. tertiolecta culture under cultivation conditions mentioned above. c The changes in chlorophyll a/b ratio of D. tertiolecta culture under cultivation conditions mentioned above. Data were expressed as mean ± standard deviation of three independent experiments (n = 3)
