Microbial ecological traditional Chinese medicine preparation for livestock and poultry from fermentation production of multiple bacterials and fermentation method thereof

The invention relates to micro-ecological Chinese medicine preparation for livestock and poultry by adoption of multi-strain fermentation production and a fermentation method. The compositions of traditional Chinese medicines in a culture medium of the fermentation preparation include: radix astragali, radix codonopsitis, Atractylodes macrocephala, Poria cocos, liquorice, medicated leaven, hawkthorn, angelica, Chinese rhubarb, Scutellaria baicalensis, radix isatidis, cordate houttuynia, sicklesenna seeds, Schisandra chinensis, Gynostemma pentaphylla, phellodendron, dried orange peel, radix bupleuri, curcuma, honeysuckle, Chinese gall, purslane and Quisqualis indica. The fermentation method is as follows: a multi-strain solid state fermentation strain is adopted for fermentation; bacillus subtilis, bacillus natto, bacillus licheniformis, beer yeast, Candida wtilis, Aspergillus niger, lactobacillus plantarum, Lactobacillus acidophilus and bifidobacteria are purified and subjected to anaerobic fermentation under the conditions of a rotating speed of 180 revolutions per minute at a temperature is 32 DEG C for 48 to 72 hours till the pH value reaches 4.0. The micro-ecological Chinese medicine preparation has the advantages that the micro-ecological Chinese medicine preparation uses probiotics to ferment different Chinese medicine compositions, and is micro-ecological Chinese medicine preparation which completely replaces antibiotics and has the advantages of no residual medicine, disease prevention, growth promotion and low cost.

Chinese medicinal herb culture medium, preparation method thereof and cultivation method of edible fungus

The invention relates to the technical field of edible fungus cultivation, in particular to a Chinese medicinal herb culture medium, a preparation method thereof and a cultivation method of edible fungi. The culture medium is made by a mixture and water, wherein the mixture is manufactured by the following components by weight percent: 65 percent to 70 percent of Chinese medicinal herbs, 30 percent to 35 percent of cottonseed hulls and 2 percent to 3 percent of calcium superphosphate; and the total weight ratio of the water and the mixture is 1 : 1. In the preparation method, the Chinese medicinal herbs are used as main culture medium to cultivate the edible fungi with the efficacies of invigorating kidney and qi, nourishing a liver, reinforcing yin and tranquilization, and the like, thereby the health-care function of the edible fungi to a human body is enhanced, and the method can be used for cultivating golden mushrooms, pleurotus eryngii, bailing mushrooms, tea mushrooms, pocket-sized mushrooms, coprinus comatus, oyster mushrooms, phoenix mushrooms, ganoderma lucidum, auricularia polytricha, auricularia auricula, dictyophora indusiata, hypsizigus marmoreus, stropharia rugoso-annulata, nameko, pleurotus abalonus, fistulina hepatica, brazilian mushrooms, mushrooms, straw mushrooms and tremella. The invention also provides the preparation method of the Chinese medicinal herb culture medium and the method for cultivating the edible fungi by using the Chinese herb culture medium.

Novel edible fungus culture medium and preparation method thereof

The invention discloses a novel edible fungus culture medium and a preparation method thereof. The novel edible fungus culture medium comprises 70-85% of main material, 15-20% of auxiliary material, 3-5% of additive material and 0.1-0.8% of absorbent resin, wherein the main material comprises sawdust, straws, corncobs, and cottonseed hull; the auxiliary material comprises bran, rice bran and maize meal; and the additive material comprises land plaster, slaked lime, calcium superphosphate, white sugar and urea. The preparation method disclosed by the invention comprises the following steps of: reasonably selecting raw materials in the ratio of nutrient ingredients according to the nutritional requirements of different kinds of edible fungi to prepare the culture medium, and adding the absorbent resin synthesized by the biological materials. The permeability and the water retaining capacity of the culture medium are greatly enhanced, and the accumulation of the various nutrient elements and the slow releasing capacity to the nutrient elements are enhanced; meanwhile, the properties of the cellulose and the protein of the absorbent resin provide the nutrition in the aspect of carbon source or nitrogen source so as to ensure the sufficient supplement of the required raw materials of the fungi; and by adopting the novel edible fungus culture medium disclosed by the invention, the output of a single bag is enhanced by 25%-35%, and the fungus output time is advanced by 4-6 days.

Production method for tea vinegar drink

The invention discloses a production method for a tea vinegar drink, and relates to the technical field of processing of drinks. The tea vinegar drink is mainly prepared from tea, momordica grosvenori, white sugar, mountain spring water and acetic acid bacterium. The production method comprises the following steps: after the momordica grosvenori is smashed, the tea, the momordica grosvenori, the white sugar, the mountain spring water and the acetic acid bacterium are respectively weighed, and the weighed raw materials are placed in a pot and boiled to obtain an extract liquid; an acetic acid bacterium strain accounting for 2-3 percent of the total weight of the raw materials is -inoculated, covered and fermented, the product temperature is controlled to be 16-28 DEG C, and the fermentation lasts 10-25 days; acid adjustment is performed on a fermented and obtained feed liquid, the total acid content of the feed liquid is controlled within a range of 0.3-1 g/100ml, and the soluble solid is controlled within a range of 3-5 percent; the tea vinegar drink is obtained via vacuum and sterile filling after the liquid is sterilized. The invention discloses the tea vinegar drink integrating multiple functions of nutrition and health care, vegetal syrup is used as an acetic acid bacteria culture medium for fermentation, the produced tea vinegar drink contains various spicy substances and nutrient ingredients of the tea, the momordica grosvenori and acetate acid, and is good in flavor and high in quality.
