The Effect of Variable Light Source and Light Intensity on the Growth of Three Algal Species.

ABSTRACT: Light is the essential energy source for autotrophically growing organisms, including microalgae. Both light intensity and light quality affect cell growth and biomass composition. Here we used three green algae-Chlamydomonas reinhardtii, Desmodesmus quadricauda, and Parachlorella kessleri-to study the effects of different light intensities and light spectra on their growth. Cultures were grown at three different light intensities (100, 250, and 500 µmol m^-2 s^-1) and three different light sources: fluorescent lamps, RGB LEDs, and white LEDs. Cultures of Desmodesmus quadricauda and Parachlorella kessleri were saturated at 250 µmol m^-2 s^-1, and further increasing the light intensity did not improve their growth. <
