Résumé
This study evaluated the electrochemical capacity of four perchlorate-reducing microorganisms (PRMs) isolated from an Altiplanic Andean watershed naturally pressured with perchlorate. Three-electrode electrochemical cells were used to test the electrochemical activity of the obtained isolates. Electrochemical evaluation (i.e., cyclic voltammetry, electrochemical impedance spectroscopy, chronoamperometry) revealed that two isolates identified as Dechloromonas sp. CS-1 and Clostridioides sp. CS-2 are electrochemically active PRMs. Bacterial isolates exhibiting cathodic peaks at -651 mV and -303 mV (vs. Ag/AgCl) for CS-1 and CS-2, respectively. Electrotrophic perchlorate removal was demonstrated by a 6-days chronoamperometry with removal rates of 27 and 17 mg L
