A strain of streptococcus sp.64 and its application

Abstract

The invention provides a streptococcus, which is a new species in the genus Streptococcus, named: Streptococcus sp.64, which is registered and preserved in the Guangdong Provincial Microorganism Culture Collection Center, and the preservation number is GDMCC No: 61194. The Streptococcus sp.64 of the present invention can produce strong antibacterial active substances after being fermented and cultured, and has obvious antibacterial effect on Pseudomonas aeruginosa and Burkholderia melioidosis, etc. The prevention and treatment of diseases caused by Pseudomonas and Burkholderia melioidosis has a broad development space, and has a good development and application prospect in the aspect of antibacterial drugs.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a strain of Streptococcus sp.64 and its application. Background technique [0002] Streptococcus is the type genus of Firmicutes, Bacilli, Lactobacillales, and Streptococcusaceae. The genus Bacteria is a common type of pyogenic coccus, which widely exists in nature, human and animal feces and nasopharynx of healthy people, and most of them are not pathogenic. Medically important streptococci mainly include Streptococcus pyogenes, Streptococcus viridans, Streptococcus pneumoniae, and Streptococcus agalactiae. With the continuous progress and development of bacterial isolation and identification methods, especially the wide application of molecular classification and identification methods, more and more streptococci have been discovered. At the same time, as of 2020, the genus has included 160 species and 29 subspecies (http: / / www.bacterio.net / streptococcus.htmL). Rese...
