Embodiment

[0026] Weigh 500kg of fresh starfish, clean the silt and put it on a drying net to dry for 10 days, put it into a pulverizer and crush it to 100 mesh, weighing 209kg. Add the crushed starfish dry powder into the reaction kettle, add 480L of ethanol with a concentration of 55% (v / v), raise the temperature to 65°C, and stir and extract for 10h. Transfer the feed liquid in batches to an industrial centrifuge for the first centrifugation, centrifuge at 3000r / min for 30min, and keep the supernatant. The supernatant was preliminarily filtered using an aqueous cellulose membrane with a pore size of 45 μm, and the filtrate was retained. Use a hollow cellulose membrane with a cut-off of 1000D to carry out ultrafiltration and concentration of the filtrate to remove impurities. During this period, 200L of purified water is added. When the volume of the concentrated solution drops to 40L, the ultrafiltration is stopped, and 14kg of ammonium chloride is added to it, and stirred until compl...

Abstract

The invention discloses a production method of a marine animal pesticide. The production method of the marine animal pesticide in particular comprises the following steps: carrying out pretreatment on raw materials, alcohol extraction, centrifugation, prefiltration, ultrafiltration concentration, salting-out, dissolution, enzymolysis, secondary ultrafiltration concentration, chromatography, third-time ultrafiltration concentration, spray drying and compounding. The whole preparation process is mild in reaction conditions and simple in technological process, and other organic solvents are not used except ethanol; saponins which are combined with proteins and polysaccharides are subjected to precipitation separation by using a salting-out method; furthermore, most of lipids are removed by the salting-out method, so that the production method of the marine animal pesticide is safer and more environment-friendly compared with the traditional method of using organic solvents of ethers and the like to remove the lipids; macromolecular proteins are decomposed into polypeptides and amino acids by immobilized enzymes to effectively reduce adsorption of macroporous resin for the proteins in subsequent processing to increase the amount of a target product in eluent. The starfish saponin content of raw material powder of the animal pesticide is analyzed by using a vanillin-sulfuric acid development process, and is 69.4-73.1%, finally, the marine animal pesticide is obtained through a compounding manner.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and in particular relates to a method for producing animal-derived pesticides by endangering animals in marine breeding industry. Background technique [0002] Starfish (starfish) belong to Echinodermata (Echinodermata), starfish class (Asteroidea). There are more than 2,000 species of starfish, which are distributed in all oceans of the world, and there are more than 100 species of starfish in my country. Starfish feed on a variety of invertebrates or animal carcasses, especially molluscs such as oysters, mussels and clams. They are the enemy of shellfish and coastal aquaculture, and seriously endanger coastal aquaculture fisheries. At present, most of the starfish in shellfish breeding areas are directly discarded or used as crop fertilizer after exposure to the sun and crushed after being caught with the net, which is a kind of pollution to the environment and also causes a waste of resou...
