Used primarily in microbiology for the cultivation of fastidious microorganisms, especially streptococci and other pathogenic bacteria that require enriched media for optimal growth. Supports the isolation and identification of bacteria from clinical specimens such as blood, urine, and throat swabs. Often used in hemolysis studies due to its ability to maintain red blood cell integrity when supplemented with blood. Suitable for antimicrobial susceptibility testing and quality control in diagnostic laboratories. Also employed in research settings for maintaining and subculturing bacterial strains.
