Thermo Scientific™ HI Broth w/6.5% NaCl, BCP (5mL)

Description

Differentiate Enterobacteriaceae from group D Streptococci using Heart Infusion Broth with 6.5% NaCl (with Brom Cresol Purple) (Salt Broth).

Differentiate Enterobacteriaceae from group D streptococci using Thermo Scientific™ Remel™ Heart Infusion Broth with 6.5% NaCl (with Brom Cresol Purple) (Salt Broth). Facklam demonstrated that the differentiation of enterococci and nonenterococcal group D streptococci was more accurate on using Heart Infusion Broth with 6.5% NaCl Modified with Indicator in combination with bile and esculin agar^1,2.

This media differentiates Enterobacteriaceae from group D streptococci. Enterococci grow in the presence of 6.5% NaCl and utilize dextrose in the medium. This medium contains beef heart infusion and casein peptone that supply nitrogenous compounds and amino acids required for the growth of streptococci. Dextrose is an energy source. Bacterial growth is enhanced by yeast extract which supplies essential B vitamins.

• Ready to use – Continence of prepared media.
• Selective media – Sodium chloride (6.5%) interferes with the membrane permeability and osmotic equilibrium and inhibits the growth of salt-intolerant bacteria

Easy to interpret -Enterococci grow in the presence of 6.5% NaCl and utilize dextrose in the medium. The metabolism of dextrose produces acid, which causes the indicator, brom cresol purple, to change from purple to yellow.
