Test media for coliforms and Escherichia coli. "AquaTest" series
This series consists of pyruvate-supplemented X-GAL-MUG media, which have been added to the culture media for the defined substrate technology. These are test media for coliforms and Escherichia coli.
Just add the sample water and culture for 24 hours. The result will be readily available: it is coliform positive if it changes to blue, and it is Escherichia coli positive if it develops fluorescence when irradiated with black light.
The manufacturer of this series is Elmex Co., Ltd. The general distributor is FUJIFILM Wako Pure Chemical Corporation.
