Deciphering simultaneous bioelectricity generation and dye decolorization using Proteus hauseri
چکیده انگلیسی

This first-attempt study disclosed how and why electron-shuttling mediators were capable to stimulate bioelectricity-generating capabilities of dye-bearing microbial fuel cells (MFCs) using Proteus hauseri. Due to significant biotoxicity of 4-aminophenol (4AP) and the absence of electron-mediating potential of 3AP, only 2AP among all isomers could work as an exogenous mediator to stimulate bioelectricity generation of P. hauseri. Dye toxicity to cells on anodic biofilm in MFCs apparently affected the performance of simultaneous bioelectricity production and color removal (SBP&CR) in MFCs. Plus, dose–response analysis upon toxicity potency of reactive blue 160 revealed that cells on anodic biofilm in MFCs had a higher tolerance to reactive blue 160 than suspended cells. Apparently, augmentation of electron mediator(s) with low toxicity was a feasible means to facilitate bioelectricity-generating capability of SBP&CR.
