Cellulolytic and electrogenic activity of Enterobacter cloacae in mediatorless microbial fuel cell

Mediatorless cellulose-fed microbial fuel cell (MFC) is a bioelectrochemical system that converts cellulose into energy through cellulose-hydrolyzing and electrogenic activity of bacteria. In the paper it has been presented that Enterobacter cloacae isolated from termite gut exhibited both cellulose-degrading and exoelectrogenic activities that make it a valuable strain to be used in a cellulose-fed MFC. The maximum power and current densities obtained from the cellulose-fed MFC were 185mW/m2 and 2.4A/m2, respectively. SEM micrographs of the anode showed that E. cloacae formed an expanded fibria system bounding bacteria cells into network attached to the electrode surface.
