Abstract

The invention relates to a method used for recycling microalgae residue and producing spirulina rich in polysaccharides. According to the method, hydrothermal carbonization is adopted to recycle nutrients in microalgae residue as nitrogen sources, carbon sources, and other nutrient elements in culturing of spirulina, conventional nutritive salt (such as sodium nitrate and urea) supplying method is replaced to produce spirulina rich in polysaccharides, the content of polysaccharide in biomass is 65% or higher, and is increased by 15 to 56% compared with that of common culture medium; polysaccharide yield is increased by 23% to 3.5 times of that of common culture medium. The method is capable of realizing resource utilization of wastes, reducing consumption of nutrient salts, increasing spirulina polysaccharide yield and quality, and reducing production cost, and is beneficial for simplifying of downstream processing operation, and promoting of industrialized production of spirulina.

Description

technical field

[0001] The present invention relates to the recovery and utilization of microalgae dregs and the cultivation of microalgae. Specifically, the nutrients such as nitrogen source and carbon source in the microalgae dregs are recovered by hydrothermal treatment and used for the production of rich-rich spirulina through appropriate dilution. polysaccharide biomass. It can be used in waste resource utilization, waste water treatment, spirulina cultivation and production of biomass, as well as food, medicine, energy and other related fields using spirulina polysaccharide as raw material. Background technique

[0002] Spirulina polysaccharide is a water-soluble polysaccharide in Spirulina cells. It has biological activities such as anti-tumor, anti-radiation, and anti-mutation. It can improve the immune function of body cells and body fluids, resist the proliferation of cancer cells, and reduce the genetic damage caused by radiation. It has broad application prospec...
