Fig. 6From: Improving carbohydrate and starch accumulation in Chlorella sp. AE10 by a novel two-stage process with cell dilutionEffects of CO2 concentration and initial NaNO3 concentrations. Growth profile (a) and total carbohydrate content in DW (b) of Chlorella sp. AE10 under different CO2 concentrations (2, 10 and 20%) at the second stage; growth profile (c) and total carbohydrate content in DW (d) of Chlorella sp. AE10 under different initial NaNO3 concentrations (1/8, 1/4, 1/2 N, and full N; full N, 1.5 g L−1) at the second stageBack to article page
