Embodiment 1

[0023] The sargasso raw material is removed from the sediment, dried or sun-dried at 55°C, and crushed; accurately weigh 100kg of the dried and crushed sargasso raw material, add fresh drinking water with a raw material weight of 600kg to the above sargasso powder, and put it in a 55°C water bath Soak for 2h; adjust the pH of the liquid to 4 with HCl, and add 0.4% cellulase composed of endo β-glucanase 40%, exo β-glucanase 30%, and β-glucose alfase 30% , Enzymatic hydrolysis for 8h; add 0.3% protease composed of neutral protease 45% and papain 55%, pectinase 0.3% composed of pectin lyase 55% and pectin esterase 45%, continue enzymatic hydrolysis for 3h, Stir and centrifuge after enzymolysis; add 10 times the weight of sargassum 2% Na to the above-mentioned sargassum after centrifugation 2 CO 3 Digest the solution in a water bath at 50℃ for 2h; then add 5 times the volume of fresh drinking water at 50-60℃ to dilute for 1h, after fully diluted, filter through 250 mesh silk screen;...

Embodiment 2

[0026] The sargasso raw material is removed from the sediment, dried or sun-dried at 65°C, and pulverized; 100kg of the dried and crushed sargasso raw material is accurately weighed, and 700kg of fresh drinking water of the raw material weight is added to the above sargasso powder in a 60°C water bath Soak for 3h; adjust the pH of the liquid to 6 with HCl, and add 0.5% cellulase composed of endo-β-glucanase 40%, exo-β-glucanase 30%, and β-glucose alfatase 30% , Enzymatic hydrolysis for 10 hours; add protease 0.6% composed of neutral protease 45% and papain 55%, pectinase 0.4% composed of pectin lyase 55% and pectin esterase 45%, continue enzymatic hydrolysis for 4 hours, Stir and centrifuge after enzymatic hydrolysis; add 12 times the weight of 4% Na of Sargassum to the above centrifuged Sargassum 2 CO 3 Digest the solution in a 60°C water bath for 3 hours; then add 6 times the volume of fresh drinking water at 50-60°C to dilute for 2 hours, after fully diluting, filter through ...

Abstract

The invention discloses a method for preparing sodium alginate and an organic fertilizer from gulfweed, 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, and (10) preparation of the gulfweed 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; and Chinese humic acid resources are fully developed and utilized, the organic fertilizer rich in humic acid and macronutrients is produced with water as a solvent, and the high-valued comprehensive utilization of undaria pinnatifida sporophylls is achieved.

Description

Technical field [0001] The invention involves the field of ponyta algae, which specifically involves a method of using sodium lignate and organic fertilizer with ponyto algae. Background technique [0002] The current world is facing huge pressure on energy shortage and environmental pollution. The development of clean renewable energy has become an important means to solve petrochemical resources and energy crises.Bioethanol has received widespread attention as a clean fuel and gasoline additive.At present, my country's preparation of fuel ethanol focuses on land source materials such as straw, sugar cane, wood chips, and cassava. [0003] Using ponyto -algae processing waste with cellulose, ponyto algae polysaccharides, and mannitol to prepare fuel ethanol, not only can ponyta algae processing waste into waste into treasure, solve environmental pollution problems, but also provide sufficient and cheap biological ethanol to prepare biological ethanolThe supply of raw materials t...
