Bile Esculin Test

What is the Bile Esculin Test? The bile-esculin test is a biochemical test performed to differentiate Enterococci and group D Streptococci from non-group D viridans group Streptococci on the basis of their ability to hydrolyze esculin. Many organisms are capable of hydrolyzing esculin, but only a few of them can do so in the presence of bile (4% bile salts …
