Preparation method of Bacillus pumilus for treating burn and metabolite

A preparation method of Bacilluspumilus for treating burns and its metabolite, belongs to the field of biotechnology. The method adopts a Bacilluspumilus USTB-06 (culture preservation number: CGMCC No. 2703, culture preservation date: October 14, 2008), and obtains a Bacilluspumilus metabolite fermentation liquor after culturing the Bacilluspumilus for 4-5 days in the Bacilluspumilus substrate, centrifugation for get the supernatant fluid and sterilization at high-temperature and high pressure. The Bacilluspumilus metabolite fermentation liquor is principally used for the treatment of burns, which not only can significantly inhibit the growth of staphylococcus aureus and Patina pseudomonas leading to the wound surface infection of burns, but also can be sprayed on the wound surface infection of burns to achieve the effect of preventing wound infection and promoting wound healing.
