摘要 | Open pond has been widely used for microalgae culture. However its lower biomass productivity damaged its economic viability used as cultivation systems for feedstock production. In this study we introduced a forced L/D circulation operation to conventional open pond, in which the culture medium was pumped to circulate between an illuminated shallow pond and a fully darkened tank. The growth of microalgae was dominated by the photic retention time and dark/light ratio of the forced L/D circulation. The optimal values were determined to be 3.98 for dark/light ratio and 5.80 min for photic retention time by response surface methodology, at which, a biomass productivity of 36.5 g m2 d1 for Scenedesmus dimorphus was approached in laboratory. Outdoor cultivation practice with the forced light/dark circulation of pond was also carried out and averaged 28.5 g m2 d1 biomass productivity was achieved, which is double of that by conventional open pondcultivations in 250 mm or 50 mm water depth without forced circulation.; Open pond has been widely used for microalgae culture. However its lower biomass productivity damaged its economic viability used as cultivation systems for feedstock production. In this study we introduced a forced LID circulation operation to conventional open pond, in which the culture medium was pumped to circulate between an illuminated shallow pond and a fully darkened tank. The growth of microalgae was dominated by the photic retention time and dark/light ratio of the forced LID circulation. The optimal values were determined to be 3.98 for dark/light ratio and 5.80 min for photic retention time by response surface methodology, at which, a biomass productivity of 36.5 g m(-2) d(-1) for Scenedesmus dimorphus was approached in laboratory. Outdoor cultivation practice with the forced light/dark circulation of pond was also carried out and averaged 28.5 g m(-2) d(-1) biomass productivity was achieved, which is double of that by conventional open pond cultivations in 250 mm or 50 mm water depth without forced circulation.
