ACTIVIDAD ELECTROQUÍMICA DE LA CEPA BACTERIANA CrLIM26 ACOPLADA A LA REDUCCIÓN DE Cr(VI)

Abstract: Palabras clave: biorreducción de cromo, densidad de potencia, Exiguobacterium acetylicum, remoción de cromo RESUMEN Las celdas de combustible microbianas (CCM) son una tecnología emergente que aprovecha la degradación de compuestos orgánicos y diferentes sustratos para generar energía, entre los cuales se encuentra el Cr(VI), metal pesado clasificado como tóxico, mutagénico y cancerígeno para los organismos vivos. El propósito de este trabajo fue determinar la actividad electrogénica acoplada a la biorremediac… Show more

“…The BioAu/GO group showed the highest Cr(VI) removal rate within 6 h of close‐circuit operation, reaching 2.17 ± 0.51 mg L −1 h, and the ChemAu/GO group (2.06 ± 0.45 mg L −1 ·h) followed, while the GP and GO groups were smaller, with 1.10 ± 0.37 and 1.56 ± 0.65 mg L −1 h, respectively. However, the Cr(VI) removal rate of the BioAu/GO group was only 0.38 ± 0.17 mg L −1 h during the close‐circuit operation for 6–24 h, which was a 4.71 times decrease compared to the first 6 h. This result may be attributed to cathode passivation caused by the production of nonconductive Cr(III) deposits with Cr(VI) reduction, which reduce the cathode electron transfer rate and microbial activity, thus affecting the Cr(VI) removal efficiency of the biocathodes 6,55‐57 …”
