Biofilm construction under constant polarisation

Electrochemically active biofilms are constructed on working electrodes (graphite, stainless steel, DSA®) under constant polarisation (from -0.5V/ECS to +0.5V/ECS depending of the aim of the study). Experiments are conducted in reactors hermetically closed, with or without gas flow. In reactors, a conventional three-electrode system is implemented with a multi-potentiostat (VMP2 Bio-Logic SA) interfaced with a computer (EC-Lab v.8.3 software, Bio-Logic SA).
