Novel spirulina platensis strain

Abstract

The present invention relates to a novel Spirulina strain having a linear-type morphology. Cells of Spirulina strain can be harvested at high yield using the Spirulina strain of the present invention.

Description

technical field [0001] The present invention relates to novel Spirulina strains having a longer linear-type morphology and methods of harvesting Spirulina strains utilizing said strains. Background technique [0002] Spirulina (Spirulina) is one of the blue-green cyanobacteria that carry out photosynthesis on the surface of lakes with high alkaline and high salinity in tropical areas. It is a high-protein food with a protein content of more than 65%. Moreover, the amino acids that make up the protein contained in spirulina all contain the essential amino acids necessary for the survival of organisms. In spirulina, lipids are 6-10%, carbohydrates are about 15-20%, with such a relatively low content, Therefore it can be used as a food resource. Moreover, spirulina contains a large amount of food pigments such as β-carotene (provitamin A) or phycocyanin (phycocyanin) with antioxidant activity, and is rich in various types of vitamins, inorganic substances, fiber, etc., and spi...

Problems solved by technology

[0004] However, even if a closed tank such as a photobioreactor is used to cultivate spirulina, the initial facility cost required for harvesting spirulina by centrifugation is high, the workload is limited, manpower needs to be frequently mobilized, and washing after harvest is very limited. Because of these problems, it is not easy to harvest

Moreover, even if the mesh body is used to harvest spirulina, the previous spirulina is in the form of a short spiral with a micron unit below 0.3mm. question

[0005] And, it is reported that NH 4 Cl is a nitrogen source that increases the initial growth rate when cultivating spirulina. For conventional spirulina, NH 4 The ammonia production of Cl leads to poor tolerance. When the nitrogen source of spirulina is used at a high concentration, it will hinder the growth. It can only be used in the cultivation of spirulina. In the cultivation of spirulina, it is mainly used as a nitrogen source. NaNO 3 , urea, etc., to replace the excellent NH 4 Cl
