Abstract
Novel nanocomposites comprised of bacterial cellulose (BC) with carboxylic multi-walled carbon nanotubes (c-MWCNTs) incorporated into the BC matrix were prepared through a simple method of biosynthesis. The biocathode and bioanode for the enzyme biological fuel cell (EBFC) were prepared using BC/c-MWCNTs composite injected by laccase (Lac) and glucose oxidase (GOD) with the aid of glutaraldehyde (GA) crosslinking. Biosynthesis of BC/c-MWCNTs composite was characterized by digital photos, scanning electron microscope (SEM), and Fourier Transform Infrared (FTIR). The experimental results indicated the successful incorporation of c-MWCNTs into the BC. The electrochemical and biofuel performance were evaluated by cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The power density and current density of EBFCs were recorded at 32.98 µW/cm3 and 0.29 mA/cm3, respectively. Additionally, the EBFCs also showed acceptable stability. Preliminary tests on double cells indicated that renewable BC have great potential in the application field of EBFCs.

Summary
More attention has been increasingly paid to eco-friendly materials because of an increased awareness of sustainable development and environmental protection [1]. Enzymatic biofuel cells (EBFCs) as the new green energy devices have drawn much attention because they are capable of harvesting electricity from renewable and abundantly available sources by using enzymes as the catalysts for oxidation of biofuels (most commonly, glucose) and reduction of oxidizers (most commonly, oxygen) [2,3]. They are renewable energy without any harmful intermediates and side products.
