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.

The present invention relates to the technical field of genetic engineering, in particular to an engineering strain of nannochloropsis oculata, and a preparation method therefor and the use thereof. The engineering strain is nannochloropsis oculata with the DWARF1 (DWF1) gene knockout. In the present invention, the strain with the DWF1 gene knockout is constructed by using CRISPR CAS9 technology on the premise of not introducing any exogenous molecular label, so that the engineering strain with significantly reduced cholesterol content and significantly increased 24-methylenecholesterol content is obtained, wherein the inheritable character of the engineering strain is stable. 4-Methylenecholesterol is a main ingredient of royal jelly, and has antihypertensive, anti-arrhythmia and vasospasmolytic activities, etc. This engineering strain, if produced industrially, helps to fill the gap in the field of microalgae with high 24-methylenecholesterol content, achieves the development of a healthy food product with high 24-methylenecholesterol content, high eicosapentaenoic acid content and low cholesterol content by using marine nannochloropsis oculata, and provides a theoretical basis for the industrial production of artificial royal jelly by using seawater and carbon dioxide.

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.
