The growth conditions of two microalgae, Spirulina platensis and Nannochloropsis oculata, were tested under various light sources including white cold DDH GaAlAs LED, traditional fluorescent lamps and natural light cultures, with no difference found in the growth of biomass, indicating that white cold DDH GaAlAs LED could replace traditional fluorescent lamps, thus providing for large saving on electricity costs and preservation of cultural space. To date, the use of white cold DDH GaAlAs LEDs as light source for microalgal cultures seems to be largely unstudied.
