Abstract
The present invention discloses a Paenibacillus strain capable of producing polysaccharides with an after-sun repair effect and use thereof. This strain is classified and named as Paenibacillus polymyxa PYQ1, preserved in China General Microbiological Culture Collection Center with a preservation number of CGMCC No. 16444. The present invention includes isolation and cultivation of strains and 16S rDNA identification; obtaining extracellular polysaccharides from fermentation product of the strain and use of the extracellular polysaccharides produced by the strains in repairing after-sun damages. The polysaccharides produced by Paenibacillus PYQ1 disclosed by the present invention can significantly improve proliferation activity of damaged cells after sun exposure, and has remarkable after-sun damage repairing effect; and as a natural product of microbial fermentation, the polysaccharides have characteristics of a low cost, simple and easy acquisition and the like, can be applied to the preparation of related after-sun repairing agents, and have a good market application prospect.
