A microelectrodes study for anaerobiosis profiles in biofilms

In questo sono presentate le potenzialità di alcuni microsensori realizzati manualmente per la misura di parametri chimico-fisici (redox, pH, conduttività, solfuri) all’interno di biofilm batterici.

The potentiality of self-made microelectrodes to measure crucial parameters (redox potential, pH, conductivity, sulphides concentration) inside anaerobic biofilms is presented. Advantages and limitations of the use of a single chamber micorbial fuel cell (MFC) as device to study anaerobic biofilms and microbial corrosion of AISI 304 SS is highlighted, in comparison with the dual-cell method.

The physico-chemical profiles and trends of microelectrodes, suitably located in the cathodic biofilm, were analyzed at different operating power of single chamber MFCs. The biofilm activity was correlated to the changes in chemistry and power production of MFCs.
