Polarization Potential Has No Effect on Maximum Current Density Produced by Halotolerant Bioanodes

摘要: Halotolerant bioanodes are considered an attractive alternative in microbial electrochemical systems, as they can operate under higher conductive electrolytes, comparison with traditional wastewater and freshwater bioanodes. The dependency between energetic performance polarization potential has been addressed several works; however the vast majority discusses its effect when or inocula employed, fewer reports focus on from highly-saline environments. Moreover, of current production is not fully understood. To determine if a significant production, eight were grown by chronoamperometry at positive negative potentials relative to reference electrode (+0.34 V/SHE −0.16 V/SHE), three-electrode set-up employing sediments hyperhaline coastal lagoon. maximum density obtained was same, despite differences applied potential. Our findings indicate that even organic matter removal coulombic efficiency obtained, had no statistically overall production.
