The application provides a coffee peel enzyme fermentation agent and a preparation method of the enzyme, and belongs to the technical field of enzyme production.The preparation method of the coffee peel enzyme comprises the following steps: mixing coffee peel powder and sugar of sweetener oil residue, and sequentially performing fermentation of Saccharomyces cerevisiae YNXC003 and anaerobic fermentation of Bifidobacterium bifidum YNXC004 to obtain the coffee peel enzyme.The coffee peel powder and the sugar of sweetener oil residue are used as composite raw materials, special bacterial agents are combined, and a segmented fermentation mode is adopted, so that the nutritional activity of the two raw materials can be fully released, the nutritional level and flavor taste of the enzyme can be significantly improved, and the enzyme can be endowed with physiological functions such as blood sugar reduction.The total acid content of the coffee peel enzyme is 8-12 g / L, the total phenol content is 1.5-2.5 g / L, the coffee peel enzyme is rich in bioactive substances such as short-chain fatty acids, polyphenol compounds and amino acids, and has a significant blood sugar reduction effect.

This invention discloses a respiratory health preparation of *Lactobacillus acidophilus* that enhances the mucosal barrier, relating to the field of microbial preparation technology. The preparation includes probiotic active ingredients and a pharmaceutically or food-grade acceptable carrier. The probiotic active ingredients consist of *Lactobacillus acidophilus* LH-001, *Lactobacillus rhamnosus* LR-002, and *Bifidobacterium bifidum* BB-003, which have been selectively adapted for respiratory use. It also includes synergistic functional components. By weight, the synergistic functional components include 1-5 parts of 2'-fucosylated lactose, 0.5-2 parts of low-molecular-weight sodium hyaluronate, and 0.1-0.5 parts of baicalin. The weight-average molecular weight of the low-molecular-weight sodium hyaluronate is 10-30 kDa. This invention obtains three functionally complementary exclusive strains through selective respiratory adaptation, and, combined with the synergistic effect of the synergistic components and targeted formulation technology, solves the problems of poor compatibility and difficult live bacteria delivery of conventional intestinal strains, achieving in-situ efficacy in the respiratory tract and meeting the needs of multiple commercial dosage forms.

This invention belongs to the fields of fermentation engineering and enzyme engineering technology, specifically relating to a method for high-yield γ-aminobutyric acid (GABA) production through mixed fermentation. Specifically, this invention employs a mixed fermentation method, promoting the growth of *Lactobacillus hessei* through the growth of *Bifidobacterium*, achieving a synergistic effect between the two strains and thus significantly increasing GABA yield. Experimental results show that compared with traditional single-strain fermentation, the mixed fermentation method can increase GABA yield by 2-3 times and shorten the fermentation cycle by more than 50%, demonstrating significant technical advantages and economic benefits. Therefore, the mixed fermentation method proposed in the above technical solution provides an efficient and environmentally friendly new approach for high-yield GABA production, possessing significant application value and market prospects.

This invention discloses a method for preparing and applying an energy-saving and environmentally friendly straw roughage, relating to the field of feed preparation technology. The preparation method includes the following steps: S1, weighing 5-20 parts by weight of corn straw powder, 5-20 parts of pearl millet, 5-20 parts of whole corn, 10-30 parts of wheat straw, 5-20 parts of locust tree leaf powder, and 1-10 parts of tree leaves and branches, and mixing them to obtain a primary feed; S2, adding a mixed microbial culture to the primary feed, wherein the mixed microbial culture includes at least *Lactobacillus plantarum* and *Bifidobacterium bifidum*; S3, adding a mold inhibitor and basic feed to the roughage containing the mixed microbial culture, and anaerobic fermenting at 35°C to produce fermented roughage. The energy-saving and environmentally friendly straw roughage preparation method according to this invention can utilize waste resources, saving energy and protecting the environment; it can also fatten edible livestock, and feeding animals with microbially fermented feed can improve their disease resistance, reduce antibiotic use, and improve meat quality.
