Description To compensate for the increase of carbon dioxide level and the energy exhaust, an enzymatic fuel cell (EFC) has been investigated by researchers. In the paper, a chemical oxidative deglycosylation of an enzyme was investigated to furture improve EFCs. By deglycosylating an enzyme, the distance between the elecrtode surface of a glassy carbon anode and the enzyme active site is hypothesized to be reduced. This reduced distance would improve the enzyme/substrate binding and the rates of electron transfer which result in a higher power EFC. However, the results were not supportive of this hypothesis. The control showed better electrochemical performances and the substrate specific activities at 100mM in a buffer at pH 6.5 than the deglycosylated enzyme. For future projects, efficient and more selective deglycosylation methods should be investigated.
