Bile Esculin Agar, Modified
Details
Bile Esculin Agar, Modified is a differential medium recommended for isolation and presumptive identification of group D Streptococci/Enterococci from food and pharmaceutical products. This medium is a modification of Bile esculin agar, M972 that differs in content of oxgall. The value of bile tolerance together with hydrolysis of esculin as a means of presumptive identification of group D streptococci/ enterococci is widely recognized. Enterococci and Group D Streptococci hydrolyse esculin to esculetin and dextrose, which reacts with ferric citrate producing brownish black precipitate, thus helping in identification and differentiation.
