The invention relates to the technical field of microorganisms, and discloses a plant lactobacillus IMAUJBP6 strain and application thereof. The plant lactobacillus IMAUJBP6 is preserved in the China General Microbiological Culture Collection Center (CGMCC), the preservation number is CGMCC No.36779, and the preservation date is November 26, 2025. The plant lactobacillus IMAUJBP6 obtained by screening can play an anti-oxidation role by inhibiting the activity of alpha-amylase and alpha-glucosidase and improving the DPPH free radical scavenging rate, the superoxide anion free radical scavenging rate and the hydroxyl free radical scavenging rate at the same time, so that the effect of reducing blood sugar is synergistically achieved. When the strain is applied to preparation of fermented milk, a fermented milk product with excellent quality can be obtained, especially when camel milk is used as a raw material for fermentation, the product shows a remarkable potential probiotic effect in the aspects of reducing blood sugar and resisting oxidation, and a new strain and a technical support are provided for development of functional fermented milk products and products for reducing blood sugar and resisting oxidation.

The present application relates to the technical field of fermentation medium, more specifically, it relates to a high-density fermentation medium for streptococcus suis and preparation and application thereof.The medium comprises beef infusion powder 1-5 parts, tryptone 1-10 parts, pancreatic casein peptone 1-10 parts, soybean peptone 1-5 parts, dipotassium hydrogen phosphate 1-5 parts, sodium chloride 1-10 parts, yeast extract 1-10 parts and glucose 1-5 parts.

The invention relates to the technical field of fermented milk products, in particular to fermented milk containing bifidobacteria with high viable count and a preparation method of the fermented milk. Specifically, when the fermented milk containing the probiotics is prepared, raw milk, white granulated sugar, wheat hydrolyzed protein powder, inulin and milk protein powder are jointly used as raw materials of the fermented milk, and the viable count of the probiotics bifidobacterium in the fermented milk is increased by using the wheat hydrolyzed protein powder, the inulin and the milk protein powder according to the mass ratio of (1-4): (1-10): (1-8). By adding the prebiotics, the milk protein powder and the plant protein powder composition into the formula, the bifidobacterium fermented milk has a remarkable value-increasing effect, and the problem that the viable count of the bifidobacterium-containing probiotic fermented milk is low is effectively solved.

The application discloses a DPP-IV inhibiting peptide-producing lactobacillus helveticus, a goat milk with blood sugar reduction and a preparation method thereof, and relates to taking goat milk as raw material, fermenting the goat milk by using the DPP-IV inhibiting peptide-producing lactobacillus helveticus KD12 to obtain the goat milk fermented by the lactic acid bacteria containing DPP-IV inhibiting peptide with blood sugar reduction, and preparing the goat milk powder fermented by the lactic acid bacteria containing DPP-IV inhibiting peptide with blood sugar reduction through drying after fermentation. The lactic acid bacteria of the goat milk fermented by the lactic acid bacteria with blood sugar reduction is inactivated to obtain the goat milk with postbiotics with blood sugar reduction, and after concentration, the goat milk powder with postbiotics with blood sugar reduction is obtained through drying. The goat milk with blood sugar reduction provided by the application has a high DPP-IV inhibition rate, can be used for inhibiting DPP-IV activity after being eaten by consumers, thereby reducing blood sugar, reducing the dosage of blood sugar reduction drugs, and thereby reducing the side effects caused by the blood sugar reduction drugs.

The application relates to the field of biological medicine, and discloses a bifidobacterium adolescentis YF-01 and application of the bifidobacterium adolescentis YF-01 in fermented milk. The bifidobacterium adolescentis YF-01 is isolated from adult feces and is preserved in the China Center for Type Culture Collection, with a preservation number of CCTCC NO: M 20251308. Experiments prove that the bifidobacterium adolescentis YF-01 has good gastrointestinal fluid tolerance, the survival rate can reach 90.1% after being treated by simulated gastric juice for 3 hours, and the survival rate can reach 72% after being treated by simulated intestinal juice for 4 hours. The self-aggregation rate of the strain is 88.83%, and the hydrophobicity is 79.41%; the strain has significant scavenging capacity for DPPH free radicals and hydroxyl free radicals, and shows good antioxidant activity and adhesion capacity, which provides a theoretical basis for the application of the strain in fermented milk. The strain and metabolites thereof can be used for preparing food, medicine or health care products with the functions of regulating intestinal flora and enhancing antioxidant capacity, and have significant application potential in the development of functional fermented milk products.

The application belongs to the technical field of utilization of waste biomass by microorganisms, and specifically discloses an abnormal williamsonia strain Y8 and application thereof in beer dreg fermentation. The preservation number of the strain is CCTCC NO: M 2026579. The strain has good tolerance to extreme chemical environments such as high salt, high sugar, strong acid and high-concentration ethanol; can ferment polysaccharides and monosaccharides; under the condition of rich nutrition, the content of cell protein can reach 57%; can adapt to the liquid physicochemical environment of beer dregs and effectively utilize beer dregs to grow. With the aid of enzyme preparation composed of beta-glucanase and xylanase, the efficiency of the strain in utilizing beer dregs to grow is significantly improved, and after 72 h of fermentation, the fermentation liquor with viable cell count of the strain ≥1.8×10 9 CFU / mL is obtained, and the prepared fermentation feed is effectively enriched with total phenols and improved in antioxidant performance. The application is green, mild and efficient, and has excellent application prospect.

This invention discloses a method for preparing a *Lactobacillus plantarum* enrichment agent and its application, relating to the field of microbial technology. The preparation method includes: extracting traditional Chinese medicine to obtain medicinal residue; enzymatically hydrolyzing the residue; adjusting the pH to neutral to obtain the enrichment agent; wherein the traditional Chinese medicine is selected from one or more of the following: dried tangerine peel, white hyacinth bean, coix seed, polygonatum, lotus leaf, dendrobium officinale, licorice, atractylodes macrocephala, poria cocos, chicken gizzard lining, roasted malt, wolfberry, kudzu root, and clove. The *Lactobacillus plantarum* enrichment agent provided by this invention uses medicinal residue as raw material and is specifically processed using a compound enzyme. It has low raw material costs, high product added value, and can significantly increase the viable count of *Lactobacillus plantarum* in a unit volume of fermentation broth, effectively reducing the cost of preparing highly active *Lactobacillus plantarum* inoculants.
