Predicting spatial patterns of soil bacteria under current and future environmental conditions

Nicolas Jean Philippe Guex, Jan Roelof van der Meer, Marco Pagni, Aline Buri

Soil bacteria are largely missing from future biodiversity assessments hindering comprehensive forecasts of ecosystem changes. Soil bacterial communities are expected to be more strongly driven by pH and less by other edaphic and climatic factors. Thus, al ...

Quantitative chemical biosensing by bacterial chemotaxis in microfluidic chips

Harald Van Lintel, Jan Roelof van der Meer, Clémence Roggo

Whole-cell bacterial bioreporters are proposed asalternatives to chemical analysis of, for example, pol-lutants in environmental compartments. Commonlybased on reporter gene induction, bioreporters pro-duce a detectable signal within 30 min to a few hoursa ...

An automated microreactor for semi-continuous biosensor measurements

Philippe Renaud, Harald Van Lintel, Jan Roelof van der Meer, Nina Buffi

Living bacteria or yeast cells are frequently used as bioreporters for the detection of specific chemical analytes or conditions of sample toxicity. In particular, bacteria or yeast equipped with synthetic gene circuitry that allows the production of a rel ...

Tunable reporter signal production in feedback-uncoupled arsenic bioreporters

Jan Roelof van der Meer, Vassily Hatzimanikatis

Escherichia coli-based bioreporters for arsenic detection are typically based on the natural feedback loop that controls ars operon transcription. Feedback loops are known to show a wide range linear response to the detriment of the overall amplification o ...

Biochip with E-Coli bacteria for detection of arsenic in drinking water

Philippe Renaud, Harald Van Lintel, Joël Theytaz, Jan Roelof van der Meer, Thomas Michael Braschler

Arsenic and other pollutants are often present in trace amounts in drinking water in a number of countries. In aqueous solutions the sensitivity of arsenic-responsive bacterial bioreporters is far better than the performance of chemical field test kits. Ho ...

Comparison of naphthalene bioavailability determined by whole-cell biosensing and availability determined by extraction with Tenax

Stefanie Kohlmeier, Jan Roelof van der Meer, Robin Tecon

A rapid biological method for the determination of the bioavailability of naphthalene was developed and its value as an alternative to extraction-based chemical approaches demonstrated. Genetically engineered whole-cell biosensors are used to determine bio ...
