Azide Dextrose Broth w/ BCP 500G

Azide Dextrose Broth w/ BCP is recommended for cultivation of faecal Streptococci. It is recommended for quantitative determination of Enterococci in water, foods, sewage and other materials suspected of contamination with sewage. It is similar in composition to Azide Dextrose Broth with the addition of Bromocresol purple. This medium is recommended by the ISO Committee for the detection and enumeration of faecal Streptococci in water as per ISO 7899-1:1984. Sodium azide inhibits growth of gram-negative bacteria, allowing Enterococci to grow. Turbidity in tubes along with colour change to yellow indicate presence of Enterococci.
