High-fat Chlorella culture solution for promoting rapid growth and preparation method thereof

Abstract

The invention relates to a high-fat Chlorella culture solution for promoting rapid growth and a preparation method thereof, belonging to the field of a biotechnology. The culture solution comprises the following components in percent by weight: 1-8% of bamboo vinegar, 4-15% of macronutrient, 0.2-0.5% of micronutrient, 0-1.5% of soil extract and 78-94% of water, wherein the macronutrient is one ofsodium nitrate, dipotassium hydrogen phosphate, potassium nitrate, magnesium sulfate, calcium chloride, potassium dihydrogen phosphate and sodium chloride or a mixture thereof, and the micronutrient is one of ferric chloride, boric acid, copper sulfate, manganese sulfate, zinc sulfate and ammonium molybdate or mixture thereof. Since the bamboo vinegar serving as a synergic ingredient is added into the culture solution, the content of the fat generated during the process of the carbon dioxide immobilization using algae is increased. The high-fat Chlorella culture solution is simple in preparation method, low in production cost, and convenient in operation, and can be used for greatly increasing the content of the fat in Chlorella; and under the same conditions, the purity of the cultured algae is very high, and the culture cost for large-scale exploitation and utilization of the Chlorella is greatly reduced.

Description

[0001] technical field [0002] The invention belongs to the field of biotechnology, and in particular relates to a high-fat chlorella culture solution for rapid growth promotion and a preparation method thereof. Background technique [0003] [0004] Chlorella is a general unicellular green algae of the Chlorella phylum Chlorella, which is a spherical single-cell freshwater algae with a diameter of 3 to 8 microns. It is one of the earliest life on earth and appeared in more than 2 billion Years ago, the genes remained unchanged. It is a highly efficient photosynthetic plant that grows and reproduces with photosynthetic autotrophy and is widely distributed. It is one of the lowest and oldest plants, it reproduces quickly, has a high oil content, and is an important source of biofuels. Chlorella is rich in protein, lipid, polysaccharide, dietary fiber, vitamins, trace elements and active metabolites, which can prevent and treat peptic ulcer, anti-tumor, enhance immunity, an...

AI Technical Summary

Problems solved by technology

At present, the technology of autotrophic culture of Chlorella has been mature, but there is a problem that light is blocked from entering the culture after the Chlorella cells are increased to a certain concentration, thus limiting the photosynthesis of Chlorella, resulting in the growth of the cultured Chlorella low biomass
