Drinking Water Microbiology

Research areas

Biological stability of drinking water

We investigate the principles behind bacterial growth at low nutrient concentrations, focussing on assimilable organic carbon (AOC), pathogen growth potential (PGP) and the influence of materials in contact with drinking water (BioMig).

Disinfection of drinking water bacteria

We investigate the mechanisms, order and kinetics of cellular damage through disinfection using cultivation-independent approaches and focussing on indigenous microbial communities.

Rapid detection methods

We develop, optimize and apply methods and tools for rapid assessment of indigenous bacterial concentrations, viability and activity in drinking water, with current focus on flow cytometry and adenosine tri-phosphate analysis.
