The culture mixture is illuminated cyclically. Spray heads are mounted on the inner side of the opposite wall of the bioreactor chamber so that 4 spray heads are arranged symmetrically around each artificial light source. The pH value of the culture mixture is maintained in a range of 8.5-9.5 by the addition thereto of a lactic acid bacteria-containing solution at the beginning of each light cycle in an amount of 1-3 ml per litre of culture mixture, said solution having a pH value selected in a range of 4.0-5.0.

In this invention there is provided an illumination system for a photosynthetic organism-growing medium. This system comprises a waterproof housing arranged to be inserted into a photosynthetic organism-growing medium and having a length along a longitudinal axis that is greater than a width. It also comprises a light source arranged to provide illumination along the length of the housing, and a diffuser arranged within the waterproof housing, the diffuser having a narrow end directed towards the light source and a wider end away from the light source and having a diffusive reflective surface arranged to diffusively reflect light from the light source to outside the housing.

Embodiments of the present disclosure describe bioreactor systems that integrate phototrophic organism cultivation with energy harvesting, methods of using said bioreactor systems, and the like. The bioreactor systems can comprise a bioreactor, wherein the bioreactor is configured to cultivate a phototrophic organism in a liquid growth medium, and at least one transparent photovoltaic panel positioned between the bioreactor and a light source, where the transparent photovoltaic panel transmits select wavelengths of light and absorbs select wavelengths of light.
