|Abstract:||The area of bioelectrochemistry is currently making the greatest impact in new biotechnology, including point of care medical devices and bioelectrochemical sensing. On the other hand, emerging bioenergy systems offer new opportunities to move away from conventional petroleum products toward more environmentally sustainable alternative approaches. As such, the branch of bioelectrochemistry dealing with energy systems is poised to have an undoubtable impact on greenenergy and bioenergy concepts. To facilitate these and other areas of study, bioelectrochemical systems (BESs), which use biological components such as bacteria (often referred to as biocatalysts) are increasingly being developed and miniaturized for a new round of biotechnology. This PhD thesis focuses on fabrication and functionality of a “three-electrode electrochemical microfluidic system” for biofilm studies of different bacteria (electroactive and non-electroactive) using different electrochemical techniques. They were broadly studied by electrochemical and microscopic imaging (optical and electron microscopy) techniques. This thesis can potentially open the way for a new wave of electrochemical biosensor development, while offering specific scientific advances in studies of biofilm biocapacitance, bioresistance, biofilm pH, nutrient dependency of biofilm activity and bacterial respiration kinetics.|
