Investigating the Functional Response of a Subsurface Biofilm Community to Xenobiotic Stress
… responses, catabolism and the stress response glutathione-gated potassium efflux (GGKE), to benzene, pentachlorophenol (PCP), or Cd exposure were studied in up-flow sand columns to examine the contribution of each response to the overall functional response of a subsurface biofilm. Benzene was …

Evaluating strategies for integrating bacterial cells into a biosensor designed to detect electrophilic toxins
… The stress response selected in this work is the glutathione-gated potassium efflux (GGKE) system, which responds to electrophilic stress by effluxing potassium from the interior to the exterior of the cell. Thus, the bulk potassium in solution can be monitored as an indicator of bacterial stress. …

Development of a Biosensor to Predict Activated Sludge Deflocculation, and the Link Between Chlorination and Potassium Efflux
… a biosensor to predict deflocculation and investigated the mechanistic cause of deflocculation relating to chlorination of activated sludge cultures. In order to effectively manage upset events, it is necessary to know the source of an upset and the causative mechanism that the source initiates. …

The Development of a Bacterial Biosensor Designed to Detect Oxidative Chemicals in Water: Correlating Sensor Relevance to Mammalian Brain Cells and Assessing Bacterial Cell Immobilization Strategies
… Gram-negative heterotrophic bacteria called the glutathione-gated potassium efflux (GGKE) mechanism is a good biological indicator to be used in a biosensor designed to detect the presence of oxidative chemicals in water. The authors of this study propose the development of a GGKE biosensor using …
