英文摘要A marine green microalga, Platymonas subcordiformis, was able to generate H2 photo-synthetically when exposed to light after a period of anaerobic, dark incubation. The growth curves were different at different light intensities, and the ability of H2 production varied significantly at different growth phases. At a higher light intensity (E=160μE/(m2•s)), the microalga grew faster, and gave a higher H2 yield. At the stationary phase, the ability of H2 production reached the maximum of a H2 concentration of 17.5% collected in 300ml culture at 3×106 cells/ml. At a lower light intensity (E=60μE/(m2•s)), the H2 yield decreased by 24% with the maximize hydrogen concentration of 17.5%, and the chlorophyll concentration reduced by 61%. The results indicated that the physiological status of algal cells have a significant effect on the ability of H2 production. Therefore optimization of physiological parameters is required to maximize hydrogen production in green algae.
