Method for culturing and carrying out enzymolysis on microalgae, application of enzymolysis product and method for extracting grease

The invention relates to an oil-producing microalgae culture and extraction technology, in particular to a microalgae culture and enzymolysis method, an application of an enzymolysis product and a grease extraction method. According to the method, the cattle urine (CU) and the water are used as the culture medium, so that the growth of the oil-producing microalgae can be effectively promoted, an important theoretical basis is provided for the development and industrial production of biological energy sources, the production cost of the microalgae is reduced, the problem of environmental pollution caused by animal husbandry excrement is relieved, and the method has great significance. According to the method, an enzymolysis method is ingeniously applied, and the use of organic reagents in a traditional extraction method is reduced to the maximum extent. The cost of oil extraction is reduced, and the utilization rate of the microalgae is also improved. The microalgae subjected to enzymolysis has relatively stro
