General description
TBX Agar (Tryptone Bile X-glucuronide Agar) is a chromogenic medium designed for the selective detection and enumeration of Escherichia coli in foodstuffs, animal feed, and water. E coli cells absorb x-glucuronide and the intracellular glucuronidase splits the bond between the chromophore and the glucuronide. The released chromophore gives blue to blue-green coloration to the colonies. The peptone provides the essential growth nutrients to the organisms. Bile salts mixture inhibits Gram-positive organisms and the high incubation temperature of 44 °C further suppresses non-target organisms.
Application
显色琼脂用于检测和计数食品、动物饮料和水中大肠杆菌的数量。
