产品介绍：

For the differentiation of E. coli from other coliforms. The presence of the enzyme β-D-glucuronidase differentiates most E. coli spp. from other coliforms. E. coli absorbs the chromogenic substrate 5bromo-4-chloro-3-indolyl-β-D-glucuronide (X-β-D-glucuronide). The enzyme β-glucuronidase splits the bond between the chromophore 5bromo-4-chloro-3-indolyle and the β-D-glucuronide. E. coli colonies are colored blue-green. Growth of accompanying Gram-positive flora is largely inhibited by the use of bile salts. The prepared medium is clear and yellowish.
