EFFECTS OF LIGHT SOURCES AND LIGHT WAVELENGTHS ON THE GROWTH AND LIPID CONTENT OF THE GREEN ALGA, Chlorella vulgaris Beij
- The effects of different artificial light sources (CFL and LED) and different light wavelength (blue, red, and white) on the growth and lipid content of the green alga, Chlorella vulgaris Beij., were investigated. Results showed both the dry biomass concentration and lipid content of the C. vulgaris, using CFL or LED, were in the order of white > red> blue. At each light wavelength the dry biomass concentration and lipid content of the C. vulgaris under LED light were both significantly higher (p < 0.05) than those obtained under CFL. The study showed the white LED light provided the best condition for growth and lipid accumulation of C. vulgaris. The use of LED light could significantly reduce the energy input for the indoor microalgal cultivation. This could help improve the economic viability of C. vulgaris for biofuel production, as well as other application.
