“…A protocol of anode modi cation has been adopted based on our previous studies where the immobilization of yeast-mediator [7] and polymerization of neutral red (PNR) [6] have been conducted to create a several types of anode modi cation design. Na-Alginate (Sigma-Aldrich, Fraance) has been applied as polymer matrix in immobilization method.…”

“…The aerobic and anaerobic conditions have been conserved, in anode and cathode chamber, respectively. In our last work, MFC based Saccharomyces cerevisiae as known as bakery's yeast has been delivered and the electron transfer has facilitated by the present of mediator as seen in Fig 1a. Neutral red was appropriated as redox mediator for migration of electron to the anode surface [6][7]. However, some MFCs operate with or without a mediator, the activity of microbes was oxidizing of organic matter realizing protons and electrons [8][9].…”

“…A glucose solution has been added during MDC perform. Meanwhile in cathode solution a ferricyanide has been selected as catholythe as observed in previous study [7]. The most usually selected as catholyte next to oxygen is ferricyanide or hexacyanoferrate (III) which value of standard potential is 0.361V/NHE.…”

“…With this perspective in mind in order to improve the electricity generation during MDC process, we propose surface modi cation. Anode modi cation has been done by biocatalyst-mediator immobilization and electropolymerization of NR at the surface of anode [6,7]. Previous study of biocatalyst immobilization reported that as a promising method and new strategy for enhancement longer working lifetime than free cell [34].…”

Microbial desalination cell (MDC) built on bio-catalytic devices modification has been studied for sea water desalination using Saccharomyces cerevisiae as biocatalyst. Here we focussed the modification of anode and this study has been confirmed that bio-catalytic devices maintenance could contribute to the long-term MDC perform during desalination process. The goal of this study is to provide and develop a sea water desalination system without requiring an energy support by applying modification of anode as electron acceptor, and the different potential charges that occur between anode and cathode can plays as driving force for electro dialysis of sea water desalination. Several types of bio-catalytic devices modification have been conducted, i.e. by immobilization of mediator, immobilization of biocatalyst or a combination of both. The optimization of each device has been characterized by cyclic voltammetry, Chronoamperometry, and applied in Microbial fuel cell prior observed in MDC. The concentrations of ion salt migration have been determined by Ion Exchange Chromatography. The profiles of surface device have been detected by Scanning electron microscope and Energy Dispersive X-ray spectroscopy. Results shows that the modification of anode could be a promising method for bioelectricity generation delivered from MDC which as simultaneously produce an electricity and sea water desalination and provide a green chemistry technology.

Microbial desalination cell (MDC) built on surface modification has been studied for seawater desalination. Herein, the bio-catalytic surface modification for maintenance the long-term MDC performance during desalination process has been developed. The goal of this study is to provide and develop a seawater desalination system without requiring energy support by applying a modification of anode as an electron acceptor, and the different potential charges that occur between anode and cathode can play as driving force for electrodialysis of seawater desalination. Yeast has been applied as biocatalyst, meanwhile neutral red has been chosen as redox mediator to facilitate the electron transport from bioactivity of cells. Several types of surface modification have been conducted, i.e. biocatalyst-mediator immobilization and electropolymerization of NR at the surface of the anode. The optimization of each device has been characterized by cyclic voltammetry, chronoamperometry, and observed in Microbial fuel cell (MFC) prior functioned in MDC. The concentrations of salt ion migration have been determined by Ion Exchange Chromatography. MFC results reported that the best configuration of surface modification was obtained from CF/PNR then applied in MDC. CF/PNR delivered the highly significant performance by having the maximum value of all tested parameters, i.e 42.2% of current efficiency; 27.11% of bio-devices efficiency; 92.5 mA m-2 of current density and also 61% of NaCl transport. The profiles of surface devices have been detected by Scanning electron microscope (SEM) and Energy Dispersive X-ray spectroscopy (EDX). A several spherical shapes around 4 nm within alginate layer have been detected from SEM images and it was confirmed as yeast, meanwhile 5.04% of N has been found from EDX spectrum and was indicated from PNR. The results show that surface modification could be a promising method for bioelectricity generation which simultaneously produces electricity and seawater desalination and provides a green chemistry technology.
