Time curves of growth, glucose consumption and glucose transport ability under different culture conditions. a Biomass accumulation under the light and dark conditions with 0.5-g/L glycine; b concentration of residual glucose under the light and dark conditions with 0.5-g/L glycine; c biomass accumulation under the light and dark conditions with 5-g/L glycine; d concentration of residual glucose under the light and dark conditions with 5-g/L glycine; e chlorophyll content under the light and dark conditions with 0.5- and 5-g/L glycine; f comparison of the glucose transport ability of A. protothecoides 0710 and the photosynthesis-deficient mutant Al64 under light and dark conditions. Glucose uptake by microalgae cells was assayed at 4 days of cultivation in the light or dark. Microalgae cells without adding d-[2-³H] glucose was used as a negative control (in the light control/ in the dark control)
