Cellulose-fueled microbial fuel cells equipped with a bipolar membrane using hydrogen phosphate as the final electron acceptor.
Objectives: A bipolar membrane microbial fuel cell (bMFC) is used to generate electricity using cellulose in phosphate buffer solution as fuel, and the mechanism of electricity generation is elucidated from five reference experiments.
Results: The bMFC was operated for 20 days using cellulose as fuel and Cellulomonas fimi. In the first reference experiment, no microorganism was used. In the second experiment, a cation-exchange membrane was used instead of a bipolar membrane. In the third experiment, the bipolar membrane was used in the opposite orientation as in the main experiment. In the fourth experiment, D2O was used instead of H2O in the cathode chamber. In the final experiment, the tris-maleate buffer was used instead of a phosphate buffer. Sufficient power generation did not occur in either reference experiment.
Conclusions: The bMFC continuously generated electricity for 20 days, and elucidated H+ and OH- react in bipolar membrane, where the counter cation of dihydrogen phosphate served as the final electron acceptor.
期刊介绍：
Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them.
All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included.
Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields.
The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories.
Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
