Description
Technical Field
The invention relates to the technical field of biological extraction, in particular to a separation and extraction method of a blue algae extract.
Background
Blue-green algae, also known as cyanobacteria and blue-green algae, is the oldest known photoautotrophic organism on earth, and dates back to about 35 hundred million years. The blue algae photosynthetic system is similar to eukaryote, has chlorophyll a, a photosystem I and a photosystem II, and can reduce carbon dioxide into organic carbon and release oxygen by utilizing solar energy. The occurrence of blue-green algae obviously influences the evolution of the earth environment, and the aerobic change of the earth atmospheric environment, which is one of the most critical events in the process of the evolution of the earth, is initiated.
Besides the photosynthetic function, the blue algae also has the following unique physiological characteristics, so that the blue algae can be subjected to explosive propagation in the early severe environment of the earth, and finally, the atmospheric environment is changed.
1. Nitrogen fixation effect
The blue algae is the only algae capable of fixing nitrogen and can be divided into nitrogen-fixing blue algae and non-nitrogen-fixing blue algae according to whether the nitrogen-fixing effect exists or not. The nitrogen fixation function of the nitrogen-fixing blue algae is to reduce nitrogen molecules into nitrogen compounds by using nitrogen-fixing enzyme. Because the nitrogenase is inactivated under the aerobic condition, some nitrogen-fixing blue-green algae also form heteromorphic cells to separate the nitrogen fixing function from the photosynthesis.
2、CO 2 Concentration capacity
CO of blue algae 2 The concentration mechanism enables the cells to remove CO from the carboxyl body 2 The concentration is concentrated to the level that the carbon-fixing enzyme works efficiently. To date, 5 different inorganic carbon absorption systems have been found in cyanobacterial cells (2 for CO absorption 2 And 3 for absorbing bicarbonate). The carbon fixing rate of the cyanobacteria cells can be adjusted by combining the carbon absorption systems in different modes so as to adapt to the change of inorganic carbon in the environment, and the cyanobacteria cells can still effectively utilize the carbon source in the low-carbon environment.
3. Low light intensity adaptability
Sunlight entering the water is absorbed and scattered by some particles and organic matters in the water, and photosynthesis of producers in the water is limited. Compared with other phytoplankton, the cyanobacterial cell contains two main pigments of chlorophyll and carotenoid, and also contains pigments such as phycocyanin, phycoerythrin, allophycocyanin and the like, has a wider light-capturing spectrum, can fully capture and utilize a light source under low light intensity, and has stronger adaptability to the low light intensity.
4. Blue algae dormant body
The cyanobacteria dormant body is a self-protection strategy for the cyanobacteria to deal with the adverse environment. When the environment is not favorable for the growth of blue algae, algae cells sink into the sediment in the form of dormancy bodies; when the environmental condition is improved, the dormancy body is revived and grows and reproduces again. For example, in the case of a low temperature in winter, the algae cells mainly sink into the water bottom in the form of dormant bodies to live through the winter, and germinate again in the spring of the next year to become the seed source of the next year blue algae outbreak.
Researches show that the blue algae contains rich amino acids, proteins, polysaccharides, biological coenzymes, biological stimulants and other nutrient components, can be used for changing waste into valuable, and is applied to fertilizers of terrestrial plants, so that the problem of separating and extracting various nutrient substances from the blue algae becomes a solution of the scheme.
