This invention discloses a red pigment-producing Streptomyces spectabilis ( Streptomyces spectabilis This invention discloses a method and application for pigment extraction from *Streptomyces spectinomyces* S-13. The method involves fermenting *Streptomyces spectinomyces* S-13 with the addition of a surfactant to extract the pigment. This method releases intracellular pigments into the fermentation broth, significantly increasing pigment yield and simplifying the extraction and purification process. The red pigment produced by *Streptomyces spectinomyces* S-13 exhibits excellent stability, antioxidant activity, and antibacterial effects, making it suitable for applications in the printing and dyeing industry. The pigment extraction method described in this invention offers advantages such as short production cycle, low cost, safety, and environmental friendliness, overcoming the limitations of traditional microbial pigment production processes, including high extraction difficulty, low yield, and limited applicability.

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.

The invention relates to the technical field of medicines, and provides a triterpenoid compound in ganoderma leukemia as well as a preparation method and application of the triterpenoid compound. Adding pure methanol according to a solid-liquid ratio of 1: 10, extracting at 60 DEG C for 2h (hour, hour), filtering to obtain a methanol extracting solution, repeating for three times, and combining filtrates; concentrating the filtrate to 1 / 5 of the original volume at 50 DEG C, and adding distilled water with the volume fraction of 2 / 3 until the methanol concentration is 60% to obtain a preparation raw material; the preparation raw materials are subjected to coarse separation in a C18 column. The invention proves that the DM (12-O-Deacetuleuccontextin M) has antioxidant activity, can inhibit the activity of alpha-glucosidase, cholesterol esterase and pancreatic lipase, and shows a multi-target lipid-lowering potential. In a high glucose induced nematode model, the DM can be used for effectively reducing lipid accumulation and lowering the level of TG (triglyceride) and NEFA (non-esterified fatty acid), and the DM can be used for effectively reducing the level of TG (triglyceride) and NEFA (non-esterified fatty acid).

The application discloses application of an orange bony fish bone antioxidant peptide in preparation of antioxidant products and belongs to the technical field of antioxidant active peptides.The amino acid sequence of the orange bony fish bone antioxidant peptide is shown as SEQ ID NO.3-14, the 12 polypeptides are proposed to have antioxidant activity for the first time, the ABTS activity and ORAC activity of the polypeptides are 1.70-4.29 times and 2.79-5.90 times of Trolox respectively.The polypeptides are proposed to activate the enzyme and non-enzyme antioxidant system in zebra fish by regulating the Keap1-Nrf2 pathway, so that the resistance of the body to oxidative stress is enhanced.The potential application of the orange bony fish bone antioxidant peptide in functional products has important significance.

This application discloses a composition and its preparation and application of permeation-enhancing liposomes, belonging to the field of cosmetic production technology. The technical solution is as follows: a composition composed of Forsythia suspensa extract, Lysimachia christinae extract and Sophora flavescens root extract, wherein the mass ratio of Forsythia suspensa extract, Lysimachia christinae extract and Sophora flavescens root extract is 2-8:0.5-3:2-6.
