Abstract

Abstract: In this study, the red LED with wavelength range of 625 ~ 627.5 nm and the blue LED with wavelength range of 464 ~ 467 nm are chosen as the light source in order to increase the lipid content of microalgae as well as to reduce the energy consumption. The highest lipid weight of Scenedesmus obliquus is achievedwith 5000lux light intensity, 12L:12D of photoperiod and blue continuous LED light which consuming 53.4 times less energy in term of the total lipid content per unit than that of tricolor energy-saving lamp. In addition, the highest biomass and lipid weight of Chlorella pyrenoidosa are achieved with 5000lux of light intensity, 8L:16D of photoperiod and red continuous LED light, which is 0.73 g/L and 0.552 g/L respectively. And it consumes 29.4 times less energy consumption for units of the total lipid content than that of tricolor energy-saving lamp. Furthermore, continuous LED light improves effect of municipal wastewater treatment as the better light source for Scenedesmus obliquus and Chlorella pyrenoidosa comparing with intermittent LED light.
