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.
