acumedia* DC Medium with BCIG

• Intended Use: DC Medium with BCIG is used in the chromogenic differentiation of E. coli from other coliforms in water samples
using the membrane filtration method.
• Product Summary: DC (Differential Coliform) Medium with BCIG is a selective and differential medium for the presumptive
identification of E. coli. This medium is enhanced by the addition of a chromogenic agent, BCIG, 5-bromo-4-chloro-3-indolyl-B-
D-glucuronide to detect glucuronidase activity. The presence of the enzyme B-D-glucuronidase differentiates most E. coli spp.
from other coliforms, and is the same enzyme used in the MUG reaction. BCIG reacts slightly differently, and when released into
the medium is insoluble, accumulating within the cell, imparting a blue to purple color to presumptive E. coli colonies.
