产品介绍：

For the simple enumeration of E. coli without the need for membranes or pre-incubation The medium has been modified by the addition of a chromogenic substrate to detect the β-glucuronidase, which is highly specific for E. coli. The advantage of the chromogenic substrate is that it requires no UV lamp to visualize the reaction, and it is concentrated within the colony, facilitating easier enumeration in the presence of other organisms, or when large numbers are present on the plate.
