Streptococcus Enrichment HiVeg™ Broth (SE HiVeg™ Broth) is recommended for enrichment of Streptococci (Enterococcus faecalis) from clinical and nonclinical samples. Bile acts as inhibitor for gram-positive bacteria other than Streptococci and sodium azide inhibits gram-negative bacteria. Esculetin in the media reacts with ferric ammonium citrate to form a gives dark brown-black coloured complex. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
