Por outro lado, a sua remoção através do uso de produtos químicos, como biocidas, pode causar impactos negativos no decorrer do processo, tais como paragens para limpeza, os elevados c...
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...
