BACTcontrol: online monitor of total and specific bacteria activity (E.coli and coliform) in water
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. This is in contrast to classical microbiological methods, which are labour-intensive and in which cultivation of the organisms is required, taking several days before obtaining reliable results (24-48 hours).
The BACTcontrol detects the microbiological activity in water. It measures the specific enzymatic activities of β-galactosidase (coliforms), β-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 which contain a fluorescent indicator. The reagents are substrate-specific for the enzyme to be detected, meaning that there is an increase in fluorescence when the enzyme is present in the sample.
