The aesculin produced by organisms positive for aesculin hydrolysis reacts with ferric citrate to form a dark brown or black complex. Ferric citrate is added as a color indicator. Gram-positive bacteria other than some streptococci and enterococci are inhibited by the bile salts in this medium. Esculetin reacts with Fe3+and forms a dark brown to black precipitate. Bile esculin agar (BEA) is a differential and selective medium and is mainly used to discern group D Streptococci and Enterococci based on the organism’s potential to hydrolyze esculin. Bile esculin medium contains esculin and peptone for nutrition and bile to inhibit Gram-positive bacteria other than Group D streptococci and enterococci. For some purposes, certain bacteria are able to hydrolyze aesculin.

Share Bile Esculin Agar Base - HiMedia Leading BioSciences Company online. Organisms capable of growth in the presence of 4% bile and able to hydrolyze esculin to esculetin. The unhydrolyzed esculin can be detected using long wave UV light at 360 nm since they will remain unchanged and fluorescence under UV light (2, 3). Bile Esculin Agar is a selective differential medium for the growth of organisms like Enterococcia, Listeria, and Yersinia enterocolitica. Bile esculin agar (BEA) is a differential and selective medium and is mainly used to discern group D Streptococci and Enterococci based on the organism’s potential to hydrolyze esculin.

BEA comprises of oxygall (bile salts, first selective ingredients) and azide (second selective ingredients), former inhibits the growth of gram positive organisms and latter inhibits the growth of gram negative organisms. Product Name HiDip™ VRBG Agar w/Neutralizers - Bile Esculin Agar w/Neutralizers REACH Registration Number This product is a mixture. Bile Esculin Agar was also shown to aid differentiation of Enterobacteriaceae, Klebsiella, Enterobacter, Serratia from other Enterobacteriaceae genera (11) on the basis of esculin hydrolysis. However, other tests such as salt tolerance should be performed for identifying Enterococci (5). Hydrolysis of esculin by bacteria can be determined in growth-supporting media like Vaughn-Levine, bile-esculin, or Pfizer selective enterococcus media or by non-growth-supporting methods like PathoTec and rapid spot tests. Selective medium recommended for the isolation and presumptive identification of intestinal enterococci BBE agar contains casein, soy peptones, hemin, and vitamin K1 as the nutritive base of the Synonym(s): 6,7-Dihydroxycoumarin-6-glucoside Formula: C15H16O9 1.5H2O Formula weight: 367.31 (340.29anhy) CAS Number: 66778-17-4 Harmonized Tariff Code: 2938.90 .

The medium is highly nutritious. Bile Esculin Agar (BEA) is a selective differential agar used to isolate and identify members of the genus Enterococcus, formerly part of the “group D streptococci”. The ability to hydrolyze esculin in the presence of bile is a characteristic of enterococci and group D streptococci. Members of the genus Enterococcus are capable of growing in the presence of 40% bile (oxgall) and hydrolyzing esculin to glucose and esculetin. Bile Esculin Agar was also shown to aid differentiation of Enterobacteriaceae, Klebsiella, Enterobacter, Serratia from other Enterobacteriaceae genera (9) on the basis of esculin hydrolysis. Bile Esculin Agar with Kanamycin. Sodium chloride maintains the osmotic equilibrium of the medium. In this medium kanamycin is added to an enriched Bile Esculin Agar, enriched with hemin and vitamin K1. Enterococcus hydrolyze esculin to products that react with ferric citrate in the medium to produce insoluble iron salts, resulting in the blackening of the medium..
