Green A Base is located in Chenghai Lake, Lijiang, Yunnan, with an area of 680 acres. It is currently the largest natural spirulina base in China with a total investment of 480 million yuan. The lake water located in the "Golden Section" of Chenghai at 100.8 degrees east longitude and 26.71 degrees north latitude is sodium bicarbonate water with a mineralization degree of 9.1 and a PH value of 9-9.3. It is rich in phytoplankton and plants and is a eutrophic area . Chenghai Lake is an inland closed plateau deep-water alkaline lake isolated from the Jinsha River 300 years ago. It is one of only three naturally growing spirulina lakes in the world. Its alkaline water quality and a 200-kilometer-free natural ecological environment allow Spirulina, an ancient, alkaloid, hi-temperature, and hi-light photosynthetic autotrophic organism to multiply and grow in Chenghai Lake, with pure quality.
Scientific testing by the Wuhan Institute of Hydrobiology, Chinese Academy of Sciences has confirmed that this area is suitable for producing high-quality Spirulina platensis. The average temperature of the water surface is 17.6-27.5 degrees. For every 1 meter of depth, the temperature decreases by 1.7 degrees and the visibility is 5 meters.
In 1984, when researchers from Yunnan University visited Chenghai Lake, they discovered that "fragrant water" appears on the lake surface at the turn of spring and summer. A large number of algae float on the lake surface, covering about 1/2 of the water surface, with a thickness of about 5 cm. By collecting "fragrant noodles" dry powder for nutritional composition analysis, the test result is as follows: the protein content is as high as 52%, which is composed of 18 amino acids.
After preliminary determination, Cheng Haihu's "Xiang Noodle Water" has at least 100 tons of dry powder at a time, which is equivalent to producing 50 tons of protein!
Immediately, the Yunnan Provincial Science and Technology Commission and relevant departments established a project to carry out the "Seventh Five-Year" and "Eighth-Five-Year Plan" for industrialization of spirulina.
In 1988, scientists succeeded in artificially cultivating spirulina by using lake water at the shore of Chenghai Lake. The first pilot plant for spirulina cultivation in China was completed, and after separation, the 680-acre Green A base was developed for China. Large spirulina base.
Green A base uses biotechnology and water treatment technology to treat spirulina wastewater, and has established a clean production system for large-scale industrial production of spirulina, so that spirulina culture medium can be recycled and reused, and the wastewater is closed and recycled with zero emissions. Achieve the goal of clean production and zero sewage discharge.
At present, the Green A base has introduced an optical fiber biological reaction system, which has improved the photothermal conversion rate of spirulina aquaculture, with an annual output of 3,000 tons.
Algae breeding and spirulina collection are established at the production base using international standards and norms. Through more than 10 years of scientific and technological research, Green A has established an algae breeding bank in algae breeding and has preserved hundreds of high-quality algae.
From the processing point of view, non-high-temperature instant drying equipment is adopted, which can dry the living spirulina in half a minute.
Spirulina and Haematococcus have been successfully used in many fields such as health products, medicines, cosmetics, and food.
