Problems solved by technology

[0002] Salina is a single-celled eukaryotic algae that lives in high-concentration salt lakes. It belongs to the genus Salina in the family Chlorophyta Chlorophyceae Volvoxaceae. It is a green single-celled algae with a small body, no cell wall, and sugar. The envelope formed by protein is the only strange life found so far that can survive in high-concentration salt water. Because it is rich in unique and rich life elements, it is praised as "the power source of cells" and "the protection agent of life" by the world's scientific community. Salina is rich in β-carotene, which can be artificially cultivated to extract glycerol or carotene, and can also be used as bait for larvae such as fish, shrimp, and shellfish; it can prevent and assist in the treatment of coronary heart disease, cardiovascular and cerebrovascular diseases in the field of medical and health , diabetes, cancer, liver disease, common stomach diseases, oral ulcers, cataracts, dry eye syndrome, reduce adverse reactions to chemotherapy, improve vision, improve i

Embodiment 1

[0012] The salina culture process involved in this embodiment includes two steps of salina propagation and β-carotene accumulation:

[0013] (1) Salina breeding: first install the light source in the salina cultivation reactor, adjust the light intensity to be 2000-4000Lx, the temperature is 25-28°C, and the weight percentage concentration of the salt in the salina culture medium is 1-1.2%. Nitrogen source (KNO 3 ) is 1-1.5mL, phosphorus source (KH 2 PO 4 ) is 0.3mL, inorganic carbon source (NaHCO 4 ) is 10-15mL, inoculate Salina salina in salina culture medium, and measure after the cultivation of salina respectively through 1-2 days of growth period, 1-2 days of logarithmic growth period and 1-2 days of plateau period Nitrogen source (KNO 3 ), phosphorus source (KH 2 PO 4 ) and inorganic carbon source (NaHCO 4 ) make it reach below 0.5mL, 0.1mL and 10mL respectively, carry out the determination of salina biomass, make it reach the highest value, and complete the repro...

Embodiment 2

[0018] Salina culture method process that present embodiment relates to is:

[0019] (1) Cultivation of Salina algae species: Introduce Dunaliella salina species from the algae bank of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Water Sciences, and carry out industrialized cultivation after three-level expansion;

[0020] (2) Salina breeding: adjust the light source placed in the salina cultivation reactor to be 3000Lx, the temperature is 28°C, the culture agent includes sodium chloride (NaCl) 10g, nitrogen source (KNO 3 ) 1mL, phosphorus source (KH 2 PO 4 ) 0.1mL, inorganic carbon source (NaHCO 4 ) 10mL, medical stone export solution 50mL, water (H 2 (0) 1000mL, inoculate the algal species whose weight accounts for 20% of the culture medium in the salina culture medium, and measure the optical density (OD value) of the salina with a spectrophotometer after the algae was cultivated for 5 days through the growth phase, the logarithmic growth phase a...

Abstract

The invention belongs to the technical field of biological culture of algae, and relates to a dunaliella culture method. The dunaliella culture method comprises the following steps: at first, regulating the light intensity and temperature in a dunaliella culture reactor to adapt to dunaliella propagation, inoculating dunaliella into a dunaliella culture agent containing a salt, a nitrogen source (KNO3), a phosphorus source (KH2PO4) and an inorganic carbon source (NaHCO4), respectively measuring the nitrogen source, the phosphorus source and the inorganic carbon source in the dunaliella culture agent after a growth period, a logarithm growth period and a platform period of dunaliella culture, making the nitrogen source, the phosphorus source and the inorganic carbon source respectively reach set values, and measuring dunaliella biomass to complete the dunaliella propagation; regulating the light intensity and the temperature to adapt to beta-carotene accumulation, respectively adding table salt, KNO3, KH2PO4 and NaHCO4 into the dunaliella culture agent to set values, culturing until the dunaliella becomes brown, and then the beta-carotene is accumulated and the dunaliella culture is completed. The dunaliella culture method is scientific and reasonable in culture process, simple in steps, stable in performance, free of external environment influence and high in product utilization rate.

Description

Technical field: [0001] The invention belongs to the technical field of algal biological cultivation, and relates to a method for cultivating salina, which can increase the propagation speed of salina, increase the biomass and promote the accumulation of beta-carotene at the same time, and the cultivated salina can be used in the technical fields of medical care and sanitation and epidemic prevention . Background technique: [0002] Salina is a single-celled eukaryotic algae that lives in high-concentration salt lakes.
