In this paper we reported a novel microbial fuel cell (MFC) based on Klebsiella pneumoniae (K. pneumoniae) strain L17 biofilm, which can utilize directly starch and glucose to generate electricity. The electrochemical activity of K. pneumoniae and the performance of the MFC were evaluated by cyclic voltammetry, scanning electron microscope (SEM) and polarization curve measurement. The results indicated that an established K. pneumoniae biofilm cells were responsible for the direct electron transfer from fuels to electrode during electricity production. The SEM observation proved the ability of K. pneumoniae to colonize on the electrode surface. This MFC generated power from the direct electrocatalysis by the K. pneumoniae strain L17 biofilm.
