HiCrome™ M-Coliconfirm Agar Base

THe medium is recommended for the selective isolation and identification of Escherichia coli and coliforms from water samples using membrane filtration technique. The chromogenic mix incorporated in the medium aids in the detection of β-glucuronidase positive organisms which gives blue coloured organisms. Coliforms produce red coloured colonies other than Escherichia coli as they reduce TTC (2,3,5-triphenyl tetrazolium chloride). Thus, the resulting colour distinction allows simple interpretation of test without further confirmation.
