摘要：

The utilization of recombinant thermophilic enzymes to construct a glucose/O-2 biofuel cell (BFC) workable in a wide temperature range with enhanced thermostability using thermophilic pyrroloquinoline quinone (PQQ) dependent glucose dehydrogenase (Tth-PQQGDH, active at even 100 degrees C) and laccase (Tth-Lcs) has been studied to improve the thermostability of BFC. In this glucose/O-2 biofuel cell system, electrodes were modified with single-walled carbon nanotubes (SWCNTs) based enzyme films. The resulting electrodes demonstrated enhanced biofuel-cell performance in wide temperature range, which allows them to be used at elevated temperatures.
