The relative enzyme activities in three Chlorella strains. The relative enzyme activities of glutamine synthetase (GS) (a), glutamate synthase/NADH-dependent (NADH-GSN) (b), glutamate synthase/Fd-dependent (Fd-GSN) (c), aspartate aminotransferase (AST) (d), alanine aminotransferase (ALT) (e), pyruvate kinase (PK) (f), and citrate synthase (CS) (g) were detected after 0, 1, 2, and 6 day of N starvation, and control (0 day of C1) value of each enzyme activity was set to 1 for easy comparison. The significance of the differences between the 0 day of each strain and other test values in 1, 2, and 6 day in the same strain in each panel was tested using a one-way ANOVA. *p < 0.05
