A high-quality seawater spirulina obtained through space breeding and its application

Abstract

The invention discloses a strain of high-quality seawater spirulina obtained through space breeding and its application. Seawater spirulina algae strain H through space breeding provided by the invention 11 Strain, the algal strain has the characteristics of fast growth rate, high content of phycocyanin, spirulina polysaccharide, β-carotene, strong outdoor adaptability, etc., and can be used in high-quality spirulina The production of phycocyanin powder, phycocyanin, spirulina polysaccharide, and spirulina oil rich in β-carotene has a high potential for development and utilization.

Description

Technical field: [0001] The invention relates to the field of spirulina cultivation, and specifically relates to a high-quality seawater spirulina obtained through space breeding and its application. Background technique: [0002] Spirulina is a kind of prokaryotic algae of Cyanophyta, Oscillatoriaceae, Oscillatoriaceae, and Spirulina. It has anti-HIV, anti-tumor, anti-oxidation, anti-radiation, anti-aging, improving gastrointestinal function, and lowering blood lipids. It has become an internationally recognized super nutrition and health food. [0003] Spirulina contains 60% protein and other rich and unique bioactive substances, such as γ-linolenic acid, phycocyanin, β-carotene, inositol, spirulina polysaccharide, vitamin B 12 , minerals, etc. Among the biologically active substances contained in spirulina, phycocyanin, spirulina polysaccharide and spirulina oil high in β-carotene have attracted much attention. Phycocyanin is a special blue pigment protein in nature. I...

Problems solved by technology

After 20 years of rapid development of China's spirulina industry, the entire industrial chain is currently facing many serious problems: 1) The homogeneity of enterprises is serious, and most spirulina farming enterprises are very similar in technology, algae species, sales channels, etc. The competition in the same ecological niche of the entire industrial chain is extremely fierce; 2) The product value is underestimated, and the spirulina breeding enterprises use spirulina powder as the terminal product, most of which are exported to foreign countries, and the profit margin is severely compressed; 3) there is a lack of spirulina deep processing enterprises , Active substances such as phycocyanin and spirulina polysaccharides have not been effectively developed; 4) The product application range is limited, and spirulina products are mainly sold in the form of health care products, and the market space is small

[0015] (2) The growth rate of algal strains used by spirulina farming enterprises is slow and cannot obtain high biomass concentration

[0016] (3) The cost of Spirulina cultivation is high, and it is easy to pollute other cyanobacteria and enrich heavy metals
