The invention discloses a composition containing water-soluble dietary fiber and insoluble dietary fiber and a preparation method thereof, which relates to the technical field of a health food. The composition comprises the following raw materials by weight percentage: 50%-90% of water-soluble dietary fiber, and 10%-50% of insoluble dietary fiber. The method comprises the following steps: (1) theinsoluble dietary fiber is placed in a pulverizer, crushed through an 80-mesh sieve, and mixed for 5 minutes to obtain a mixture A; (2) the water-soluble dietary fiber is passed through the 80-mesh sieve and mixed for 5 minutes to obtain a mixture B; and (3) the mixture A and the mixture B are uniformly mixed to obtain a composite dietary fiber powder. The purpose of the present invention is to prepare the composition containing the water-soluble dietary fiber and the insoluble dietary fiber for use in diet therapy for chronic diseases such as weight loss, cardio-cerebral vascular disease anddiabetes, while avoiding the shortcomings such as too fast gastrointestinal peristalsis caused by imbalance of dietary fiber and other physical discomfort such as abdominal distension.

The invention relates to a zymotic fluid for biofermentation and a preparation method thereof. The zymotic fluid comprises the following components in percentage by weight: 0.3-0.8 percent of a saccharomyces sake liquid, 0.3-0.8 percent of a streptomyces griseus liquid, 0.3-0.8 percent of a lactobacillus liquid, 30-50 percent of rice wine distiller's grains, 10-30 percent of biomasses and the balance of purified water. A product can be obtained by performing static biological liquid fermentation on the components. Compared with the prior art, the zymotic fluid has the advantages of low preparation cost, high nutrient yield, extremely rich components, high stability, capability of serving as a bio-fermentation food, full replacement of a chemical synthesis nutritional additive in the conventional cosmetics by adding into skin care products, relatively low preparation cost, safe and stable quality, and fundamental solving of the problems of small quantity of nutritional substances, single or mixed components and poor stability existing in skin care products.

The invention belongs to the field of traditional Chinese veterinary medicine, and in particular relates to a traditional Chinese medicine composition for treating young animal dysentery, which is a preparation mainly prepared from raw materials in the following weight ratio: 12-48 parts of Radix Paeoniae Rubra; 2-8 parts of Phellodendron Phellodendri ; Purslane 1 to 4 parts; Chunpi 1 to 4 parts. The composition of the invention is simplified, the quality is safe and stable, and the water solubility is good, which is convenient for animals to take; the absorption is fast, the curative effect is easy to exert, and the drug stability is good, which is convenient for storage and transportation; Obvious improvement and treatment effect, among which the cure rate for chicken pullorum is as high as 92%, and the cure rate for piglet dysentery is as high as 80%; the invention has little toxic and side effects, and effectively solves the drug resistance caused by the large amount of antibiotics used in the market at present question.

The invention discloses a biological preparation method of blue pigment. Recombinant Escherichia coli is used as a strain, activated, and the activated Escherichia coli is inserted into a fermentation medium for expanded culture, and then placed in a fermentation tank for continuous fermentation. Enter sterile air, and maintain the pH value of the fermentation broth within the range of 6.8 to 7.2. When the content of residual sugar in the fermentation tank is less than 1 g / L, feed the material, continue to ferment for a period of time, and separate and purify to obtain blue pigment. The biological preparation method of the blue pigment of the invention realizes the mass production of the blue pigment, has less pollution, is economical and convenient, and is suitable for the fields of cosmetics, food, health care and the like.

The invention discloses an ocean element electrolysis concentrated product and a manufacture method thereof. The manufacture method comprises the following steps of: mixing a mineral powder component prepared from shells of marine invertebrates with a seawater component in a preset proportion to form a mixed liquid; and electrolyzing the mixed liquid to form an electrolytic concentrated liquid with preset components and pH value being larger than 7. By using an electrolysis processing method, the pH value and various mineral substances in the electrolytic concentrated liquid can be controlled, and residual chlorine in the mixed liquid, which is possibly harmful to the human body, can be effectively removed, therefore, the ocean element electrolysis concentrated product which has safer and relatively stable quality and is suitable for varied applications.

The invention discloses a recombinant cell, a gene modifying reagent for a cell and a gene modifying method for a reserved locus of a cell genome. The recombinant cell is used for over-expressing a first nucleic acid molecule; the first nucleic acid molecule is used for encoding a Cas9 protein or a derivative of the Cas9 protein; and compared with the Cas9 protein, the derivative of the Cas9 protein has no DNA cleavage activity, but remains target recognition activity. By using the recombinant cell, Che-chiRNA or Che-gRNA and tracrRNA can be transferred into the recombinant cell, so that genome editing or gene expression control can be easily carried out, and furthermore the gene modification on the reserved locus of the cell genome can be effectively realized.

The invention provides a compound microbial starter, biologically fermented feed prepared by using the starter and a preparation method thereof. Aspergillus niger, saccharomyces and Bacillus subtilis in the composite microbial starter are synergistically synergistic at a specific ratio to enhance the fermentation effect. The formula of fresh citrus pomace, rice bran, bran, stone powder and magnesium sulfate in the biological fermentation feed is reasonable. The biologically fermented feed of the invention meets the requirements of natural pigments, organic mineral elements, dietary fibers, probiotics and metabolites thereof required for the production of high-quality livestock and poultry meat, and has broad application prospects and market value.

The invention discloses an extract capable of assisting in lowering blood sugar and blood fat and a preparation method thereof, and relates to the fields of health food, functional food, new resource food and the like. It is mainly made from partridge tea leaves through selection, decoction, concentration, elution with macroporous adsorption resin, and drying. The pharmacodynamic experiments of the extract of the present invention show that the partridge tea extract has the function of assisting in lowering blood sugar and blood fat, and has high safety, good water solubility, strong tea fragrance, pleasant taste, and is convenient to take or eat. It can be made into various dosage forms such as capsules, tablets, oral liquids or granules, and can also be prepared into foods such as herbal teas, beverages, and candies.
