Get a Comprehensive Understanding Of Spirulina

Spirulina is distributed in saline-alkali lakes with sufficient light and suitable temperature. It was first found in Lake Chad in Africa and is also distributed in Ordos saline-alkali Lake in China. Spirulina likes high temperature and is resistant to salt and alkali; It mainly relies on simple cell division to proliferate, without sexual reproduction, and can be adapted to mariculture after domestication.

Spirulina has a high protein content, containing a special pigment protein - phycocyanin, turnip and vitamins, containing a large number of essential elements and trace elements for the human body. Human consumption of spirulina has a long history. Commercial aquaculture is mainly used for the production of health products, production of high-grade aquatic feed, extraction of phycocyanin and so on

S.platensis, S. maxima and S. subsalsa, which are commonly used in large-scale production at home and abroad, are a kind of ancient and low prokaryotic aquatic algae.

What is the chemical composition of spirulina ?

The chemical composition of spirulina has the characteristics of high protein, low fat and low sugar, and contains a variety of vitamins and trace elements, and the nutritional value is very high.
The protein content of spirulina is as high as 60%-70%, which is twice that of soybeans, 3.5 times that of beef, and 4 times that of eggs, and it contains a complete range of essential amino acids and reasonable composition.
The fat content of spirulina is generally 5%-6% of the dry weight, of which 70%-80% is unsaturated fatty acid (UFA), especially the content of linolenic acid is up to 500 times that of human milk.
The cellulose content of spirulina is 2%-4%, and the cell wall is mainly composed of collagen and hemicellulose, and the absorption rate of the human body is as high as 95%.
Spirulina vitamin and mineral content is also extremely rich, the former including vitamins B1, B2, B6, B12, E and K; The latter includes zinc, iron, potassium, calcium, magnesium, phosphorus, selenium, iodine and other trace elements, the proportion of biological zinc and iron of spirulina is basically consistent with the physiological needs of the human body, and is most easily absorbed by the human body.
In addition, phycocyanin (CPC), algal polysaccharide (PSP), gamma-linolenic acid methyl ester (GLAME), beta-carotene, chlorophyll a and other active components in spirulina have regulatory effects on many animal functions

What are the other applications of spirulina?

For medical research
The content of fatty acids in spirulina is low, of which the unsaturated fatty acids which are very beneficial to the human body account for a large proportion. Spirulina is rich in a variety of bioactive ingredients, such as beta-carotene, phycobilin, gamma-linolenic acid and endogenous enzymes, which are very beneficial to human health.

Used as feed additive
Because of its rich protein and amino acids, and rich in a variety of trace elements, spirulina has been widely used as a feed additive in animal feed, some researchers have reported the application of this new green feed additive in aquaculture and livestock production. The results showed that adding 4% spirulina - okra powder could improve the growth performance of Penaeus albinus. It has been reported that spirulina can improve the performance of piglets.

For bioenergy
As early as the 1970s, due to the occurrence of the oil crisis, the concern for clean, pollution-free and renewable bioenergy has become a hot spot, especially the preparation of biohydrogen energy. Many countries have invested a lot of manpower and material resources in the research of biological hydrogen production technology, and have accumulated a lot of research results. It has been found that compared with other biological hydrogen producing materials, spirulina has the characteristics of high photosynthetic efficiency, fast growth and reproduction, high hydrogenase activity, and long continuous dehydrogenation time, which is one of the ideal materials for the study of biological dehydrogenation. [1]

For environmental protection
In the process of growth and reproduction, spirulina needs to absorb and consume nutrients such as nitrogen and phosphorus in the water environment and degrade organic matter in the water, and has the characteristics of fast growth and reproduction, high light efficiency and strong adaptability. These characteristics of spirulina suggest that using wastewater to cultivate spirulina, on the one hand, can purify water and reduce the degree of eutrophication of water; On the other hand, high value-added spirulina products can also be obtained. Therefore, the application of spirulina in wastewater treatment is a good biological pollution control measure.
