Tryptone Bile Agar is used to detect E. coli in food and water. The recovery results are more safer, more reliable and more accurate. Most E. coli can be distinguished from other coliforms by the presence of glucuronidase. The chromogenic agent - X-glucuronide was used to detect the activity of the enzyme. E. coli cells absorb X-glucuronide and intracellular glucuronidase hydrolyze X-glucuronide to form chromophoric groups and glucuronide. The chromophore causes the colonies to appear in color. Peptone provides important nutrients for growth. Bile salts inhibit the growth of Gram-positive bacteria. Description About Tryptone Bile X-glucuronide agar(Tbx Agar):
TBX Agar also known as Tryptone Bile X-glucuronide Agar is a chromogenic medium for the detection and enumeration of E. coli in foodstuffs, animal food and water.
Chromogenic Agar for the detection and enumeration of Escherichia coli in foodstuffs, animal food and water without further confirmation. E. coli colonies are coloured blue-green.
