Bioanode performance in bioelectrochemical systems: recent improvements and prospects
Trends in Biotechnology, 2009In a bioelectrochemical system (BES) operated with a bioanode, the anode performance plays an important part in the overall performance. Fundamental aspects of bioanodes have been intensively investigated, enabling us to better understand the growth, kinetics functioning and interactions of anodophilic microorganisms.

Electrically conductive, immobilized bioanodes for microbial fuel cells
Nanotechnology, 2012The power densities of microbial fuel cells with yeast cells as the anode catalyst were significantly increased by immobilizing the yeast in electrically conductive alginate electrodes. The peak power densities measured as a function of the electrical conductivity of the immobilized electrodes show that although power increases with rising electrical ...

Two‐Stage Oxidation of Glucose by an Enzymatic Bioanode
Fuel Cells, 2013AbstractThe present study reports the design of a novel bioanode to deeply oxidize glucose in an enzymatic biofuel cell (EFC). This enzymatic glucose cell utilizes three co‐immobilized enzymes: NAD‐dependent glucose dehydrogenase (GDH), NAD(P)+‐dependent gluconate‐5‐dehydrogenase (Ga5DH), and diaphorase (DI).

Nitrated carbon nanoblisters for high-performance glucose dehydrogenase bioanodes
Biosensors and Bioelectronics, 2016Recently, many strategies are being explored for efficiently wiring glucose dehydrogenase (GDh) enzymes capable of glucose (fuel) oxidation. For instance, the use of GDh NAD(+)-dependent for glucose oxidation is of great interest in biofuel cell technology because the enzyme are unaffected by the presence of molecular oxygen commonly present in ...

In order to investigate the possibility of the normal bioanode and bioanode switched to biocathode for the bio-electrochemical degradation of the antibiotic chloramphenicol (CAP), both the bioanode acclimated with CAP and the biocathode inversed from bioanode were monitored for CAP degradation in the bio-electrochemical system. The results demonstrated

A metallacarborane redox mediator for an enzyme-immobilized chitosan-modified bioanode
Bioelectrochemistry, 2010We describe here the first report of a metallacarborane complex as a redox mediator in a functioning biofuel cell. Specifically, we have prepared a water-soluble salt of the complex anion [commo-3,3'-Fe-(closo-2,1-C(2)B(9)H(11))(2)](-) and employed it as a redox mediator for glucose oxidation using chitosan/multiwalled carbon nanotube-modified ...

Conductive Carbon Nanotube Hydrogel as a Bioanode for Enhanced Microbial Electrocatalysis
ACS Applied Materials & Interfaces, 2014Enhancing microbial electrocatalysis through new material design is essential to the efficient and stable operation of bio-electrochemical system (BES). In this work, a novel conductive carbon nanotube (CNT) hydrogel was fabricated by electrodepositing both CNT and chitosan onto a carbon paper electrode and used as a BES anode electrode.

On the nature of the electrochemical response in mediated bioanodes with yeast cells
BioelectrochemistryHerein, the electrochemical responses of Saccharomyces cerevisiae cultivated in YPD medium were tested in amperometric mode using microanalytical screen-printed electrodes modified with potassium ferricyanide and 1,10-phenanthroline-5,6-dione as mediators. The electrochemical signals obtained correlated well with the yeast growth curve. Electrochemical
