Electricity generation from wheat straw hydrolysate and the microbial ecology of electricity-producing microbial communities developed in two-chamber microbial fuel cells (MFCs) were investigated. The power density reached 123 mW/m 2 with an initial hydrolysate concentration of 1,000 mg chemical oxygen demand (COD)/liter, while coulombic efficiencies ranged from 37.1 to 15.5%, corresponding to the initial hydrolysate concentrations of 250 to 2,000 mg COD/liter. The suspended bacteria found were different from the bacteria immobilized in the biofilm, and they played different roles in electricity generation from the hydrolysate. The bacteria in the biofilm were consortia with sequences similar to those of Bacteroidetes (40% of sequences), Alphaproteobacteria (20%), Bacillus (20%), Deltaproteobacteria (10%), and Gammaproteobacteria (10%), while the suspended consortia were predominately Bacillus (22.2%). The results of this study can contribute to improving understanding of and optimizing electricity generation in microbial fuel cells.

“…Another group led by Gangrekar, also evaluated the performance of microbial fuel cells (MFCs) using an earthen pot (MFC-1) and a proton exchange membrane (MFC-2) [24]. Many researchers have found that electron transfer to the anodes could be self mediated if bio-films get formed efficiently on the anode surface [25][26][27][28]. In a different investigation, Torres et al showed how proton transport inside a bio-film limits current generation by anode respiring bacteria [29].…”

Abstract-Microbial fuel cells (MFCs) are promising clean energy sources for simultaneous recycling of organic waste while harvesting electricity. As for the different effects of electrode materials on the power performance of MFCs, a new material of electrode, carbon nanotube/polyaniline carbon paper (CNT/PANI carbon paper) was utilized and compared with other traditional carbon paper/cloth in this study. Results show that a lower ohmic loss and a better power performance were executed by using CNT/PANI carbon paper. These findings further exhibit its feasibility to improvement of power performance in MFCs.Index Terms-Electrode, microbial fuel cells, carbon nanotube / polyaniline carbon paper. I. INTRODUCTIONThe exhaustion of petroleum stores and the impending energy crisis will result in the future destruction of the environment. To help prevent this, seeking clean and renewable energy to replace traditional petrochemical energy has been continued. Here, the microbial fuel cells (MFCs) are one of green energy sources because MFCs uses microorganisms as a substrate and possesses active electrodes using the microorganism metabolism to produce electricity. The working principle of a microbial fuel cell is similar to that of a fuel cell. But, the main difference between them is the microorganisms' function in the microbial fuel cell to carry out the energy conversion [1].The microbial fuel cell can be divided into direct microbial fuel cells and indirect ones [2]-[4]. A typical MFC consists of an anode chamber and a cathode chamber separated by a proton exchange membrane (PEM) whose available source is multiple [4]- [7]. As for the electrode materials, graphite particles, graphite felt, carbon paper, carbon cloth, reticulated vitreous carbon (RVC) and carbon brush were often used previously.Concerning the feature of different electrode material resulting in different activation polarization losses [1], [2], Pt and Pt black electrodes are superior to graphite, graphite felt and carbon cloth electrodes for power performance, but their costs are much higher [8]. Schröder et al.,[9] reported that using a platinumized carbon cloth electrode in E. coli MFC with a current density of 0.84mA/cm 2 would be greater than Manuscript received October 23, 2012; revised January 18, 2013.

In addition, a value of electricity generation with1.45mA/cm 2 was obtained by using a platinumized carbon cloth electrode with polyaniline.
