The invention relates to the fishing industry or the biogas sector, in particularly to microalgae cultivation technologies for obtaining biomass. The invention is a modular open raceway pyramidally arranged with an increased light transmission for a microalgae cultivation system. The use of a transparent material for the production of open-type microalgae cultivation ponds (1) provides greater light access to the microalgae cultures, ensuring higher microalgae productivity. Pyramidally-structured cultivation ponds (1) provide 33 % land savings and 60 % more natural light access compared to the one level cultivation ponds. The invention is intended for the cultivation of microalgae with high biomass productivity, which can be further used as a raw material for the production of bioenergy or high-value products. The cultivation of microalgae can be carried out using wastewaters (e.g. liquid digestate from biogas plant) and flue gases as source of nutrients and carbon for microalgae, which will also result in wastewater treatment and reduction of CO2 emissions.

Phototropin is a blue light receptor, which mediates a variety of blue-light elicited physiological processes in plants and algae. In higher plants these processes include phototropism, chloroplast movement and stomatal opening. In the green alga Chlamydomonas reinhardtii, phototropin plays a vital role in progression of the sexual life cycle and in the control of the eye spot size and light sensitivity Phototropin is also involved in blue-light mediated changes in the synthesis of chlorophylls, carotenoids, chlorophyll binding proteins. We compared the transcriptome of phototropin knock out (PHOT KO) mutant and wild-type parent to analyze differences in gene expression in high light grown cultures (500 µmol photons m-2s-1). Our results indicate the up-regulation of genes involved in photosynthetic electron transport chain, carbon fixation pathway, starch, lipid, and cell cycle control genes. With respect to photosynthetic electron transport genes, genes encoding proteins of the cytochrome b6f and ATP synthase complex were up regulated potentially facilitating proton-coupled electron transfer. In addition genes involved in limiting steps in the Calvin cycle Ribulose-1 ,5-bisphosphate carboxylase/oxygenase (RuBisCO), Sidoheptulose 1,7 bisphosphatase (SBPase), Glyceraldehyde-3-phosphate dehydrogenase (3PGDH) and that mediate cell-cycle control (CDK) were also up regulated along with starch synthase and fatty acid biosynthesis genes involved in starch and lipid synthesis.
