This invention proposes a culture medium and cultivation method for Tremella fuciformis, belonging to the field of Tremella fuciformis cultivation technology. It is prepared from the following raw materials in parts by weight: 0.5-1 parts antibacterial agent, 5-7 parts traditional Chinese medicine residue, 3-5 parts sugarcane bagasse, 2-3 parts fermentation extract, 30-40 parts cottonseed hulls, 7-10 parts wheat bran, 0.5-1 part gypsum, and 50-60 parts sterile water. The Tremella fuciformis culture medium obtained by this invention can significantly inhibit the growth of pathogenic bacteria during cultivation, reduce the pathogenicity rate, and increase the yield of Tremella fuciformis. Simultaneously, it increases the content and efficacy of active substances in Tremella fuciformis, producing selenium-enriched Tremella fuciformis polysaccharide. The active substances exhibit excellent antioxidant, anti-inflammatory, anti-tumor, moisturizing, hypoglycemic, hypolipidemic, and cardiovascular protective effects. Using this invention's culture medium, along with a suitable ratio of Tremella fuciformis and Clematis chinensis symbiotically, provides a new method and material for Tremella fuciformis cultivation, resulting in Tremella fuciformis with better utilization value and broad application prospects.

The application relates to a preparation method and application of a ginsenoside-loaded triple-assembled Pickering emulsion, and belongs to the biomedical technology field. In order to solve the problems that the Pickering emulsion constructed by natural active ingredients in the prior art has insufficient mechanical strength of an interface film, is easy to break and lose stability, has passive release behavior, lacks controllability and environmental responsiveness, and is difficult to realize precise release, a ginsenoside-loaded triple-assembled Pickering emulsion is provided. Through a three-step cascade strategy of "molecule-interface-function", a stable "metal-phenol coordination network" interface layer is constructed on the surface of oil droplets, the physical and chemical stability of the emulsion is fundamentally improved, a Pickering emulsion which is all-natural, highly stable and has a pH response intelligent release function is successfully constructed, and the triple-assembled Pickering emulsion has significant advantages in stability, controllable release and function integration, and provides a feasible technical strategy for a response type delivery system design based on natural products.

The present application relates to a bacillus subtilis TN, a live bacterial preparation and a preparation method and application thereof, and belongs to the technical field of microorganisms. The bacillus subtilis TN was preserved in the Guangdong Provincial Microbial Culture Collection Center on March 8, 2023, and the strain preservation number is GDMCC No: 63246, and the preservation address is No. 100, Martyr Road, Guangzhou City, Guangdong Province. The bacillus subtilis TN and the live bacterial preparation provided in the present application can effectively avoid the problem of secondary infection of a burn wound caused by an unsuitable bandaging therapy, or the problem of dysbacteriosis and drug resistance caused by the abuse of biological preparations such as antibiotics when the bacillus subtilis TN and the live bacterial preparation are applied to treat a burn wound, and have the effects of anti-inflammation, antioxidant, inhibition of melanin production and moisturizing, are beneficial to promoting wound recovery and preventing scarring, and through compounding with a nutrient solution, the problems of difficulty in survival of the bacillus subtilis when applied to a wound and poor film-forming hemostatic effect are effectively solved.

The present invention provides: a novel sphingolipid which is in liquid form at room temperature due to a low melting point, and which blends easily with a variety of vegetable and / or animal oils; and a dermatologic composition for external application comprising the novel sphingolipid.
