Bile Esculin HiVeg Agar, 5KG

Bile Esculin HiVeg™ Agar is recommended for isolation and presumptive identification of group D Streptococci from food and pharmaceutical product. Bile Esculin HiVeg™ Agar is used for the isolation and identification of Group D Streptococci from food. Enterococci and Group D Streptococci hydrolyse esculin to esculetin and dextrose, which reacts with ferric citrate producing brownish black precipitate. Identification of enterococci and differentiation of Group D strptococci from non Group D can thus be performed using this agar medium. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk. Appearance of Powder: Brownish yellow colored may have slightly greenish tinge, homogeneous, free flowing powder Gelling: Firm, comparable with 1.5% Agar gel Color and Clarity: Yellow colored, clear to slightly opalescent gel with a bluish tinge forms in petri plates Reaction: Reaction of 6.45% w/v of MV972 or 6.35% w/v of MV340 aqueous solution is pH 6.6 ± 0.2 at 25°C Cultural Response: Cultural characteristics observed after an incubation at 35 - 37°C for 18-24 hours in an increased atmosphere of carbon dioxide
