A New Species of Streptococcus and Its Application

Abstract

The invention provides a streptococcus, which is a new species in the genus Streptococcus, named: Streptococcus sp.76, registered and preserved in Guangdong Microbial Culture Collection Center, and the preservation number is GDMCC No: 60774. The streptococcus Streptococcus sp.76 of the present invention can produce stronger bacteriostasis active substance after fermenting and cultivating, and all have more obvious bacteriostasis to Staphylococcus aureus and Salmonella typhi etc. There is a broad space for development in the prevention and treatment of diseases caused by Salmonella, and it 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 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...
