Reports Summarize Enzymes and Coenzymes Study Results from Tokyo University of Science (Fabrication of Carbon-Felt-Based Multi-Enzyme Immobilized Anodes to Oxidize Sucrose for Biofuel Cells)

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Enzymes and Coenzymes have been published. According to news reporting out of Tokyo, Japan, by NewsRx editors, research stated, "A carbon-felt-based multi-enzyme immobilized bioanode for biofuel cells has been successfully developed. The combination of four enzymes, namely, invertase, mutarotase, glucose oxidase, and fructose dehydrogenase, makes it possible to use sucrose-a disaccharide-as fuel for the bioanode."

Our news journalists obtained a quote from the research from the Tokyo University of Science, "The new electrode exhibits a high oxidation current density of about 12 mA cm(-2) (0.25 V vs. Ag/AgCl) in a McIlvaine buffer solution containing sucrose at pH 6.0 in the half-cell configuration. A sucrose/O-2 biofuel cell composed of the bioanode and an opposite biocathode, including bilirubin oxidase as the enzymatic electrocatalyst, was fabricated, and the new device demonstrated a maximum power density of 2.90 mW cm(-2) with an open-circuit voltage of 0.69 V in the McIlvaine buffer solution."

According to the news editors, the research concluded: "The biofuel cell fabricated using our multi-enzyme anode operates in commercially available beverages that contain only sugar, even without glucose."
