“…Based on the great interest in exploring alternative technologies to face the huge discharge of the high toxic compound-laden wastewater, development of cost-effective BES configuration with the high applicable potential (Solanki et al, 2013) and energy reservation characteristic is in urgent need (Chen et al, 2010;Sun et al, 2009). In this study, a novel system, application-oriented horizontal continuous-flow PFB-BER was designed as the simulated modified biological treatment unit in sewage treatment plant.…”

“…For example, the dual-chamber systems possessed the higher internal resistance, leading to the lower electron transfer efficiency and the higher running cost. In comparison, the single-chamber BESs, such as air-cathode single-chamber BES (Sun et al, 2009) or up-flow single-chamber BES (Cui et al, 2012), possessed with a low internal resistance or reduced construction and operation costs. However, in term of scale enlargement, the scalability of up-flow BESs is restricted based on its size, weight and excess energy requirement to overcome the gravitational effects.…”

h i g h l i g h t sA plug-flow baffled bioelectrocatalyzed reactor (PFB-BER) was constructed. Membrane-less design of PFB-BER resulted in a low internal resistance. Effects with different HRT and number of electrode assembly were evaluated. PFB-BER showed superior Alizarin Yellow R (AYR) decolorization performance. a r t i c l e i n f o t r a c tAn application-oriented membrane-free, continuous plug-flow baffled bioelectrocatalyzed reactor (PFB-BER), was designed and testified for the decolorization of Alizarin Yellow R. Decolorization efficiency (DE) with an external power source of 0.5 V was higher than without electrolysis, i.e. 93.4% versus 73.6% (HRT of 24 h). Product formation efficiencies of p-phenylenediamine and 5-aminosalicylic acid were above 95% and 50%, respectively. When HRT decreased to 8 h and 4 h, DE reduced to 69.9% and 44.9%, respectively. An additional electrode assembly improved DE to 96.4% (HRT of 8 h) and 80% (HRT of 4 h), while energy consumption (HRT of 4 h) was lower than that of HRT of 12 h with single electrode assembly under comparable DE. The PFB-BER with higher removal capacity, lower internal resistance and energy consumption provides a new solution to treat the high loading azo dye-containing wastewaters.

“…As a matter of fact, several thorough studies using mixed cultures (Chen et al 2004;Chen 2007;Chen and Chang 2007) all pointed out cooperative not competitive characteristics to maximize species diversity were the most ecologically stable strategy in face of pollutant threat for "survival to the fittest. " In particular, regarding reductive decolorization and bioelectricity generation (Sun et al 2009(Sun et al , 2011, decolorized metabolites (e.g., aromatic amines; Chen et al 2011aChen et al , 2011b identified as redox mediators via GC-MS analysis played a crucial role to stimulate operation performance (ca. 40-70% increases in electron transfer capabilities of MFCs; Han et al 2015).…”

This review tended to decipher the expression of electron transfer capability (e.g., biofilm formation, electron shuttles, swarming motility, dye decolorization, bioelectricity generation) to microbial fuel cells (MFCs). As mixed culture were known to perform better than pure microbial cultures for optimal expression of electrochemically stable activities to pollutant degradation and bioenergy recycling, Proteus hauseri isolated as a "keystone species" to maintain such ecologically stable potential for power generation in MFCs was characterized. P. hauseri expressed outstanding performance of electron transfer (ET)-associated characteristics [e.g., reductive decolorization (RD) and bioelectricity generation (BG)] for electrochemically steered bioremediation even though it is not a nanowire-generating bacterium. This review tended to uncover taxonomic classification, genetic or genomic characteristics, enzymatic functions, and bioelectricity-generating capabilities of Proteus spp. with perspectives for electrochemical practicability. As a matter of fact, using MFCs as a tool to evaluate ET capabilities, dye decolorizer(s) could clearly express excellent performance of simultaneous bioelectricity generation and reductive decolorization (SBG and RD) due to feedback catalysis of residual decolorized metabolites (DMs) as electron shuttles (ESs). Moreover, the presence of reduced intermediates of nitroaromatics or DMs as ESs could synergistically augment efficiency of reductive decolorization and power generation. With swarming mobility, P. hauseri could own significant biofilm-forming capability to sustain ecologically stable consortia for RD and BG. This mini-review evidently provided lost episodes of great significance about bioenergysteered applications in myriads of fields (e.g., biodegradation, biorefinery, and electro-fermentation).

“…Those electrons were accepted by anode electrode as the electron acceptor in anaerobic condition. In many studies it was found that electricity can be generated from various sources of organic matters such as domestic [3], composite vegetable waste [4], various food industries [5], starch processing [6,7], brewery wastewater [8,9], cheese whey [10], palm oil mill effluent [11], sewage sludge [12], decolorization in wastewater treatment [13], leachate wastewater [14]. Those reports had also proved that microbial fuel cell could be used for wastewater treatment and simultaneously producing electricity in various conditions.…”

Abstract. This study was demonstrated that the alkaline feeding in the anode chamber could enhance the electricity generation from a single chamber microbial fuel cell (SCMFC). The SCMFC was operated in batch mode. The substrate was cassava wastewater from a flour factory in Roi-Et province, Thailand and the concentration of COD value was controlled between 1,086  50.06 mg/L. The pHs were varied from acidicity (pH 5.0 and 6.0), neutral (pH 7.0) and alkalinity (pH 8.0 and 9.0) by adding NaOH. The temperature was controlled at 30 ๐ C. The maximum power density could be generated to 22.19 W/m 3 from pH feed at 9.0. Whereas at pH feed of 8.0, the second highest power density at 16.70 W/m 3 was gained. The maximum efficiency of COD removal (92.83 ± 1.37%) was obtained from pH of 8.0. The maximum of coulombic efficiency (CE) was 47.8% which was obtained from pH feed of 9.0. The alkalinity feed enhanced the power generation by increasing the alkalinity and conductivity in the anode chamber more than other feeds. It was also found that the pH feed which was nearly close to neutral would enhance the wastewater treatment by SCMFC. E Keywords: Single microbial fuel cell, cassava wastewater treatment, alkaline feed, pH.
