It has been shown that single-frequency micro-pulse lighting during the Chlorella sp. cultivation copying the duration of dark and light phases of photosynthesis results in a significantly lower yield of biomass than the constant lighting. A two-frequency mode of lighting by rectangular light impulses was suggested; it provides for the superimposition of low-frequency regime of alternating of longer light impulses and dark intervals on high-frequency regime of short light impulses and dark intervals. It was shown that the suggested mode of lighting ensures an almost twofold decrease in energy consumption in comparison with the constant mode of lighting.

Key words:  dark period,  energy saving,  light impulse,  microalgae,  micro-pulse lighting,  phototrophs,  single-frequency and two-frequency modes of lighting.
