New streptococcus strain and application thereof

Abstract

The invention provides a streptococcus, which is a new species in streptococcus, is named as Streptococcus sp.76, is registered and preserved in Guangdong Microbial Culture Collection Center, and has a preservation number of GDMCC No: 60774. The streptococcus sp.76 disclosed by the invention can generate relatively strong bacteriostatic active substances after being subjected to fermentation culture, has a relatively obvious bacteriostatic effect on staphylococcus aureus, salmonella typhi and the like, and has a wide development space in prevention and treatment of diseases caused by the staphylococcus aureus, the salmonella typhi and the like; good development and application prospects are realized in the aspect of antibacterial drugs.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a new strain of streptococcus 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). Resear...
