Freshwater eukaryoticmicroalgae culture method

Abstract

The invention discloses a freshwater eukaryoticmicroalgae culture method. The method includes steps: (1), providing culture equipment used for culturing freshwater eukaryoticmicroalgae, wherein the culture equipment comprises a reaction container, a light emitting device, a nutrition distributing device and a gas supply device, the reaction container is used for containing a culture solution for microalgae growth, the light emitting device provides light needed for microalgae growth in the reaction container, the nutrition distributing device is used for providing nutrients needed for microalgae growth and reproduction and can provide manganese ions for the culture solution, and the gas supply device is used for providing gas needed for microalgae growth in the reaction container; (2), culturing the freshwater eukaryotic microalgae in the culture equipment. An infrared light source is adopted in the method, and a proper amount of manganese ions are provided into and a proper amount of carbon dioxide is fed into the culture solution, so that microalgae culture efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a method for cultivating freshwater eukaryotic microalgae. Background technique [0002] Microalgae biomass is the future development direction of biomass utilization. It has the characteristics of high energy conversion efficiency. Compared with ordinary terrestrial crops, the yield per unit area can be dozens of times higher, so that industrial farming can be realized. The basic principle of microalgae growth is to use microalgae photosynthesis to convert carbon dioxide into microalgae's own biomass to fix carbon elements, and synthesize oil, protein, polysaccharide, cellulose and other biomass through microalgae's own characteristics and functions . Use physical or chemical methods to transform the useful substances in microalgae cells to the outside of the cells, and then refine and process them to produce biodiesel, algae polysaccharides and other products. Therefore, ...

AI Technical Summary

Problems solved by technology

Although the microalgae cultivation photoreactor in the prior art is compared with the direct cultivation in the open air such as raceway ponds and multi-stage ponds, the cultivation density and the output per unit area are significantly improved, but due to the growth of microalgae and the directional induction of effective substances, the The light source is still natural light, and the use of sunlight by microalgae is not sufficient, which is uncertain and uncontrollable, completely contrary to the stable and continuous requirements of factory production, and auxiliary breeding functions such as nutritional supplementation and carbon dioxide inflation have not been automated. , so that there is still a large distance from the actual industrial application

[0004] Therefore, there is an urgent need for a technology in the art that can overcome the disadvantages of poor controllability, low degree of automation, and low efficiency of the microalgae cultivation photoreactor in the above-mentioned prior art.
