specific Embodiment approach 1

[0010] Specific embodiment one: present embodiment utilizes yellow pulp water and waste molasses fermentation to produce the method for bioactive feed, carries out according to the following steps: one, the preparation of fermentation substrate: waste molasses and yellow pulp water are mixed, and the mass concentration of making is 15% to 25% mixture, add urea according to 2% to 5% of the mixture mass, then adjust the pH value to 2.5 to 4.5 with 5mol / L HCl or NaOH solution, and sterilize at 120°C for 25 to 30 minutes. Obtain the fermentation substrate; 2. Activation of strains: pick Candida tropicalis and Geotrichum candidum strains, inoculate them on wort solid slant medium respectively, and cultivate them at 28°C for 36 hours; pick lactic acid bacteria strains and inoculate them into MRS culture On the base, cultured at 37°C for 16-18 hours; 3. Preparation of primary seed liquid: Inoculate all the activated strains of Candida tropicalis and Geotrichum candidum prepared in ste...

Abstract

A method for producing bioactive feed by utilizing yellow seriflux and waste molasses through fermentation relates to a method for producing bioactive feed. The method solves the problem that the wastes in the current starch factories, such as yellow seriflux and molasses alcohol waste liquor are directly discharged and pollute the environment. The method comprises the following steps: 1. preparing fermentative substrates; 2. activating strains; 3. preparing first-stage seed liquor; 4. preparing second-stage seed liquor; 5. preparing third-stage seed liquor; 6. preparing seed liquor in the workshop; 7. carrying out fermentation production in a 50 m<3>-fermentation tank; and 8. drying, thus obtaining the bioactive feed. The method realizes waste utilization, and no waste liquor is produced in the production process, thus not polluting the environment. The bioactive feed produced by the method contains rich protein, active lactobacillus, trace elements, vitamins and various nutrient substances, the cell number is not less than 2*10<10> / g, the living bacteria rate is not less than 85% and the content of the crude protein is over 50% of the total mass of the feed. The method is applied to the feed field.

Description

technical field [0001] The invention relates to a production method of bioactive feed. Background technique [0002] During the corn starch production process, a large amount of soaking water will be produced, commonly known as yellow pulp water. At present, most small and medium-sized starch factories discharge it as waste, and the soaking water contains a large amount of organic matter, so COD (chemical oxygen demand) and BOD (biological oxygen demand) are very high, which will cause a sharp drop in oxygen content in the water, eventually leading to A large number of aquatic organisms died. In addition, these organic substances will also produce sulfur dioxide and nitrogen oxides during the decomposition process, causing air pollution. [0003] Waste molasses is a by-product of glucose production, most of which are used to produce alcohol, but at the same time a large amount of alcohol waste liquid is produced, causing serious pollution to the environment. The dry matte...
