Embodiment 1

[0079] Preparation of arginine concentrated bacterial liquid dry powder:

[0080] Arginine bacteria producing strains are inoculated into medium containing glucose, peptone, ammonium sulfate and sodium glutamate and fermented for 64 hours to obtain arginine fermentation liquid. Put 16 tons of arginine fermentation broth into a 20-ton container and let it stand. Add sodium polyacrylate, a flocculant with a final concentration of 250ppm, to the arginine fermentation broth, adjust the pH value to 6.5 with sulfuric acid with a mass fraction of 40%, and react at a temperature of 50°C for a reaction time of 80min. Then, use a pressure of 3MPa to Put the reacted arginine fermentation hydraulic pressure into the filter press for 60 minutes to obtain arginine concentrated bacteria liquid wet powder with a water content of 35%, and dry it into 10% arginine concentrated bacteria Dry powder.

Abstract

The invention relates to a method of producing an active peptide powder for aquatic products, livestock and poultry through fermentation of chrysanthemum meal. The method includes the steps of: 1) with the chrysanthemum meal, soybean meal, arginine concentrated bacterial slurry dried powder and corn steep liquor dry powder as raw materials and bacillus subtilis, arginine producing bacteria, rhodotorula benthica and lactobacillus plantarum as initial bacterial strains, respectively performing liquid seed cultivation and fermenting cultivation; 2) uniformly mixing a solid and a liquid according to ratio, placing the mixture on a fermentation bed and feeding sterilized air to perform aerobic solid fermentation cultivation; and 3) drying, crushing and sieving the product to obtain the active peptide powder for aquatic products, livestock and poultry. The active peptide powder has certain source of raw materials for fermentation, wherein the chrysanthemum meal, the arginine concentrated bacterial slurry dried powder and the corn syrup powder are low in cost and can produce a large amount of fermentation products. The active peptide powder is added to feeds for aquaculture and livestock and poultry breeding, thereby improving growth capability, improving product quality and also improving breeding environment. The active peptide powder is a green, environment-friendly and functional feed additive used for the aquatic products, livestock and poultry.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a method for producing active peptide powder for aquatic livestock and poultry by fermenting chrysanthemum dregs. Background technique [0002] Chrysanthemum meal, also known as chrysanthemum powder, is a by-product obtained by extracting lutein from marigold flowers grown in Northeast China, Inner Mongolia, Xinjiang and other places. It is green and fibrous, and its properties are similar to alfalfa powder. It is widely used in In livestock, poultry, fish and other feeds, it can replace bran and bran raw materials in various feed ratios, and is a very good green and health-care feed material. [0003] Main components of chrysanthemum meal: protein content 12%, ashes content 8%, moisture content 14%. Chrysanthemum meal is a pigment feed that can improve the skin color of animals and the color of eggshells, and is rich in various vitamins such as VC and VB. [000...
