Online monitor of total and specific bacteria activity (E.coli and coliform) in water

Based on fluorescent measurement
of specific enzymatic activity:

  • ß-Glucuronidase -> indicates E.coli
  • ß-Galactosidase -> indicates Coliform activity
  • Alkaline Phosphatase -> Total

The BACTcontrol is an “early warning system”, complementing the officially accepted methods for the detection of microbiological activity.

The measurements are realized in a short period of time, 1-2 hours, depending on the sampling volume and cleaning procedures. This is in contrast to classical microbiological methods, which are labor-intensive and in which cultivation of the organisms is required, taking several days before obtaining reliable results (24-48 hours).

The BACTcontrol is an online automated instrument for the detection of microbiological activity in water. It measures the specific enzymatic activities of ß-galactosidase (coliforms), ß-glucuronidase (E.coli) and alkaline phosphatase (total activity, biomass), as an indicator of the presence of bacterial contamination. The enzyme activity is detected by adding reagents (consumables) which contain a fluorescent indicator.
