Description:

Many studies have proven that the type of light source and the lighting regime have significantly influenced the efficiency of microalgae biomass production and the taxonomic composition of the cultivated biomass, as well as its chemical composition. The aim of the study was to determine the influence of the light source on the productivity of Chlorella vulgaris biomass cultivating on anaerobic digestate. The criterion for dividing experiment into variants was the light source used.It was found that the light source significantly influenced the Chlorella vulgaris growth. The highest biomass production was observed in variants with the fluorescent tube-warm light (color temperature 3000K) and the LED-warm light with 2 local maximum at 450 nm and 580 nm (color temperature 6500K). In variants with the pressure sodium lamp with the essential spectrum 570-620 nm (color temperature 2700K), the production of microalgae biomass was the lowest.The removal efficiency of organic compounds expressed as COD and BOD5 as well as ammonium and total nitrogen were dependent on the final concentration of biomass in the culture medium. In variants with the highest biomass production, the lowest concentrations of these indicators in the culture medium were observed. Phosphorus compounds were removed effectively from the culture medium regardless of the light source and the concentration of microalgae biomass.
