The influence of hydrogen bubble formation on the removal of Pseudomonas fluore...

Hydrogen bubble formation on the surface of platinum electrodes as a means of removing biofilms was studied. Biofilms of Pseudomonas fluorescens of different ages were grown on platinum electrodes and challenged with hydrogen bubbles formed at the surface of the electrodes, by cycling the potential at -2.0 V. The removal of the biofilms from the surfaces was assessed by direct epifluorescence microscopy. The re...

Monitoring biofilm formation by using cyclic voltammetry : effect of the experi...

The effect of experimental conditions on cyclic voltammetry experiments on platinum electrodes covered with biofilms formed by Pseudomonas fluorescens for 2 hours was investigated. Results show that recycling the potential stabilizes the shape of the cyclic voltammogram after 135 cycles, but the observation of the electrodes by epifluorescence microscopy showed that cells are still adhered to the platinum surfa...

The use of cyclic voltammetry to detect biofilms formed by Pseudomonas fluoresc...

The development of an electrochemical detector to monitor the in situ formation of biofilms is described. The detector consisted of an electrochemical cell containing three electrodes, whose response to the application of a potential profile to the working electrode was sensitive to the amount of biofilm present on the surface. The electrochemical technique used was repetitive cyclic voltammetry. Differences be...

The effect of experimental conditions on cyclic voltammetry experiments on platinum electrodes covered with biofilms formed by Pseudomonas fluorescens for 2 hours was investigated. Results show that recycling the potencial stabilizes the shape of the cyclic voltammogram after 130 cycles, but the observation of this electrode by epifluorescence microscopy showed that cells are still adhered to the platinum surfa...

An electrochemical detector for biofilm formation

On-line detectors of biofilm - platinum electrodes - were calibrated and validated in the laboratory under defined conditions, using a bacterium known as a good biofilm producer, Pseudomonas fluorescens. The electrochemical technique used was cyclic voltammetry.

Effect of the medium composition on the current of steady state voltammograms o...

Steady state voltammetric currents of both neutral and charged species obtained at microelectrodes are affected by the medium composition. Experiments carried out in N,N-dimethylformamide (DMF) and toluene/DMF mixtures for the reduction of diciano(fluoren-9-ylidene)methane and the methylviologen cation and for the oxidation of ferrocene, in the presence of different electrolyte concentrations indicate that both...
