Changes of growth and pigments concentration in microalgae strains. a Growth in the wild-type (with or without glucosamine treated) and the four transformants under normal cultivation. b Growth in high-CO2 cultivated microalgal strains. c Growth in wild-type P. tricornutum strains with different concentrations of glucosamine treatment. d Changes of chlorophyll a + c and focuxanthin content in high-CO2 cultured wild-type and transgenic strains. Data were shown as mean values ± SD for three independent experiments. WT the wild-type P. tricornutum strain, Glucm glucosamine
