The invention discloses an absorption enhancer and preparation method for improving the oral bioavailability of polypeptides, relates to the field of biological health care technology, including arginine grafted hyaluronic acid complex, enzyme inhibitor, and promotion auxiliary agent; the mass fraction of arginine grafted hyaluronic acid complex in the absorption enhancer for improving the oral bioavailability of polypeptides is 60-65%; the mass fraction of enzyme inhibitor in the absorption enhancer for improving the oral bioavailability of polypeptides is 5-8%; the rest are: promotion auxiliary agent; the enzyme inhibitor is pepstatin; the absorption enhancer for improving the oral bioavailability of polypeptides prepared by the method of the present invention is remarkable for the absorption effect of polypeptide oral liquid. The absorption enhancer prepared by the present invention is mainly capable of improving the absorption of components such as protein polypeptides by the gastrointestinal tract, making it easier to enter the physiological system circulation through the physiological barrier of the intestinal tract, improving absorption efficiency, and then improving oral bioavailability.

This invention discloses a gold extraction process and system using whole-sludge cyanidation without pre-concentration, relating to the field of gold beneficiation and smelting technology. It solves the problems of low grinding efficiency, complex processes, difficulty in recovering coarse gold particles, and high safety risks in existing processes. The process includes raw ore crushing, primary grinding, gravity separation, hydrocyclone classification, secondary grinding-leaching, leaching-adsorption, smelting, and tailings treatment; the system includes corresponding crushing, primary grinding, gravity separation, hydrocyclone classification, secondary grinding-leaching, leaching-adsorption, smelting, and tailings treatment units. The key innovation is: gravity separation recovers coarse gold particles after primary grinding; the secondary stage uses an azin mill to achieve synergistic grinding-leaching, eliminating the pre-concentration stage; and the filtrate reagents are recycled. This invention features a simplified process, low energy consumption, high gold recovery rate, and safe and environmentally friendly operation, suitable for gold extraction from gold ores containing coarse gold particles that require fine grinding.

The present invention belongs to the field of new material technology, and relates to the preparation of carbon fiber, and specifically to a method for improving the carbon yield of viscose-based carbon fiber. The method comprises the following steps: (1) soaking the viscose yarn in water at 80 to 90°C, ultrasonically cleaning it after soaking, and then soaking it in triethanolamine and diammonium phosphate solution in turn for catalytic treatment; (2) drying the catalytically treated viscose yarn, and then pre-oxidizing and stretching it at 220 to 280°C to obtain pre-oxidized yarn; (3) carbonizing and stretching the pre-oxidized yarn in a nitrogen atmosphere, and then cooling it to room temperature to obtain viscose-based carbon fiber. The present invention inhibits the production of L-glucose tar substances during the pre-oxidation and carbonization process, reduces the amount of tar during fiber carbonization, thereby reducing the decomposition loss of carbon and improving the carbon yield of viscose-based carbon fiber.

The present application belongs to the field of microbial application and feed processing technology, and discloses a bacillus subtilis, named bacillus subtilis YT1, which is preserved in China Center for Type Culture Collection, located at Wuhan University, No. 299, Bayi Road, Wuchang District, Wuhan City, Hubei Province, with a preservation number of CCTCC NO: M 20242767 and a preservation date of December 10, 2024. The present application also discloses a microbial preparation and the application of the bacillus subtilis or the microbial preparation in the processing of silage. The present application first simultaneously possesses high efficient lignocellulose degradation ability, excellent fermentation promotion characteristics, significant antioxidant activity and good probiotic characteristics in a strain of bacillus subtilis. This characteristic enables a single bacterial agent to achieve multiple goals such as fiber degradation, fermentation promotion, oxidation protection, which traditionally requires multiple compounded bacterial agents, and fundamentally overcomes the problems of poor compatibility between strains, unstable synergistic effect and high application cost of existing compounded additives.
