产品介绍:
For the detection and enumeration of E. coli in foodstuffs, animal food, and water without further confirmation. E. coli colonies are colored blue-green. The presence of the enzyme β-D-glucuronidase differentiates most E. coli sp. from other coliforms. E. coli absorbs the chromogenic substrate 5-bromo-4-chloro-3-indolyl-β-D-glucuronide. The enzyme β-glucuronidase splits the bond between the chromophore 5bromo-4-chloro-3-indolyl and the β-D-glucuronide. Growth of accompanying Gram-positive flora is largely inhibited by the use of bile salts.
