“…Samples were diluted 10-fold in deionized water, and glucose was assessed by ion chromatography (Dionex Wommelgem, Belgium; Carbopac1 column with borate and amino trap; ED40 pulsed amperometric detection) (15). Gas chromatography (Intersmat IGC 120 MB) was used for determination of the CO 2 and CH 4 contents in the headspace (38). H 2 was measured by using a Microtox exhaled hydrogen monitor (GMI, Wendelstein, Germany), and the detection limit was 5 parts per million by volume (14).…”

Microbial fuel cells hold great promise as a sustainable biotechnological solution to future energy needs. Current efforts to improve the efficiency of such fuel cells are limited by the lack of knowledge about the microbial ecology of these systems. The purposes of this study were (i) to elucidate whether a bacterial community, either suspended or attached to an electrode, can evolve in a microbial fuel cell to bring about higher power output, and (ii) to identify species responsible for the electricity generation. Enrichment by repeated transfer of a bacterial consortium harvested from the anode compartment of a biofuel cell in which glucose was used increased the output from an initial level of 0.6 W m ؊2 of electrode surface to a maximal level of 4.31 W m ؊2 (664 mV, 30.9 mA) when plain graphite electrodes were used. This result was obtained with an average loading rate of 1 g of glucose liter؊1 day ؊1 and corresponded to 81% efficiency for electron transfer from glucose to electricity. Cyclic voltammetry indicated that the enhanced microbial consortium had either membrane-bound or excreted redox components that were not initially detected in the community. Dominant species of the enhanced culture were identified by denaturing gradient gel electrophoresis and culturing. The community consisted mainly of facultative anaerobic bacteria, such as Alcaligenes faecalis and Enterococcus gallinarum, which are capable of hydrogen production. Pseudomonas aeruginosa and other Pseudomonas species were also isolated. For several isolates, electrochemical activity was mainly due to excreted redox mediators, and one of these mediators, pyocyanin produced by P. aeruginosa, could be characterized. Overall, the enrichment procedure, irrespective of whether only attached or suspended bacteria were examined, selected for organisms capable of mediating the electron transfer either by direct bacterial transfer or by excretion of redox components.Biological fuel cells are a potential green energy technology. In a microbial fuel cell bacteria do not directly transfer the electrons which they produce to their characteristic terminal electron acceptor; instead, these electrons are diverted toward an electrode (anode). The electrons are subsequently conducted over a resistance or power user toward a cathode, and thus, bacterial energy is directly converted to electrical energy (35). Three main types of biofuel cells can be distinguished: photoautotrophic-type biofuel cells (38), more common heterotrophic-type biofuel cells, (9) and sediment biofuel cells (3). Biofuel cells have some characteristics that are similar to those of traditional power sources, as well as to those of anaerobic reactors. They can be described on the one hand by electrochemical parameters, such as power density (in watts per square meter of electrode surface), current output, and cell voltage, and on the other hand by biological parameters, such as the nutrient loading rate and biological/chemical oxygen demand (in kilograms per cubic meter per day) (34).

“…A single photosynthetic fuel cell may be capable of both of these modes of action. Recent examples include the work of Seon et al (1993), Yagishita et al (1999) and Tsujimura et al (2001b). Seon et al (1993) constructed a photomicrobial hydrogen generating bioreactor using immobilised Rhodospirillum rubrum KS-301 in Ca-alginate beads.…”

“…The current output was found to be dependent on both the photosynthetic and respiratory activity of the cyanobacterium. Tsujimura et al (2001b) produced a photomicrobial biofuel cell with no special fuel requirement, in which the photosynthetic anodic reaction is the oxidation of water to produce dioxygen and protons. This was done using Synechococcus sp.…”

This review considers the literature published since 1994 on microbial and enzymatic biofuel cells. Types of biofuel cell are classified according to the nature of the electrode reaction and the nature of the biochemical reactions. The performance of fuel cells is critically reviewed and a variety of possible applications is considered. The current direction of development of biofuel cells is carefully analysed. While considerable chemical development of enzyme electrodes has occurred, relatively little progress has been made towards the engineering development biofuel cells. The limit of performance of biofuel cells is highlighted and suggestions for future research directions are provided.

Photobioelectrochemical cells are devices which have been developed over the past few decades and use photosynthetic catalysts for solar energy conversion or biofuel production. In this paper, a critical review of reported photobioelectrochemical systems is presented. The systems discussed include several types of photobioelectrocatalysts: whole cells, organelles, and enzymes. Special attention is paid to power or product generation as well as immobilization and electron transfer strategies used. The issues that need to be addressed in order for such systems to compete with current technologies are also discussed.
