Abstract: An application of collagen peptide in the preparation of an allergen preparation auxiliary material. For an allergen preparation, the auxiliary material thereof does not contain biological macromolecules, but contains the collagen peptide, avoiding the risk of potential allergies caused by the introduction of an inactive substance protein. The allergen preparation containing no biological macromolecule auxiliary materials can be stored stably for three years at room temperature. For allergic patients, the allergen preparation is a highly effective, stable and safe drug.

Abstract: A growth-promoting bacterial agent capable of improving content of soybean oil, preparation method, and use thereof are provided. The growth-promoting bacterial agent is fermented by a DW1 strain, the classification name of the DW1 strain is Bacillus sp., the DW1 strain is deposited in the China Center for Type Culture Collection on Jul. 16, 2021, and the deposit number is CCTCC NO: M 2021889. The growth-promoting bacterial agent of the present disclosure has the ability to dissolve insoluble phosphorus and insoluble potassium and can increase content of readily available phosphorus and readily available potassium in the soil, which has an obvious promoting effect on the growth of soybean and improves soybean yield. The growth-promoting bacterial agent of the present disclosure promotes bacteria and can significantly improve the content of soybean oil. At the same time, it has an affinity of soybean agglutinin and can agglutinate with the soybean agglutinin.
