Problems solved by technology

[0006] At present, the extraction of sodium alginate by enzymatic extraction is not mature enough, and only a single cellulase is used for hydrolysis, but the plant cell wall consists of cellulase, hemicellulase, pectin, lignin and other components. The link between them is either mosaic or cohesion, so it is difficult to completely break the cell wall of the plant with a single enzyme, and the contents cannot be completely released

Abstract

The invention discloses an enteromorpha prolifera high-valued extraction method, and is characterized in that the method comprises the following steps: (1) raw material pretreatment, (2) cellulose enzymolysis, (3) proteolysis, (4) brine digestion, (5) dilution and filtration, (6) decoloring, (7) CaCl2 solution treatment, (8) ion exchange, (9) preparation of sodium alginate, (10) preparation of ethanol, and (11) preparation of an enteromorpha prolifera organic fertilizer. A composite enzyme is prepared from protease, pectinase and cellulase by a scientific ratio, and raw material is pretreated, so as to help to improve the extraction rate of sodium alginate; at the same time, fuel ethanol is prepared by using cellulose-rich enteromorpha prolifera processing waste; the enteromorpha prolifera organic fertilizer is prepared through concentration, spray drying and granulation, so as to realize the high-valued comprehensive utilization of enteromorpha prolifera, and develop marine biological energy.

Description

technical field [0001] The invention relates to the field of utilization of Enteromorpha, in particular to a high-value extraction method of Enteromorpha. Background technique [0002] At present, the world is facing the huge pressure of energy shortage and environmental pollution, and the development of clean and renewable energy has become an important means to solve the crisis of petrochemical resources and energy. Bioethanol has been widely concerned as a clean fuel and gasoline additive. At present, the preparation of fuel ethanol in my country mainly focuses on terrestrial raw materials such as straw, bagasse, wood chips and cassava, but there are few studies on the preparation of bioethanol from marine biological resources, and the technical research on the development of enteromorpha biomass energy is relatively backward. [0003] The ocean area is huge, and there are rich Enteromorpha resources, which have various types, high photosynthetic efficiency, and short gr...
