The Gram-posiiive bacterium Enterococcus faecalis was investigated to test its ability to electrochemically communicate with electrodes. E. faecalis cells were successfully "wired" to gold electrodes through [Os(2,2'bipyridine)(2)-poly(N-vinylimidazole)10C1]2(+/+) redox polymer. Maximum current density achieved in response to 10 mM o-glucose was 18 +/- 1 mu A cm(-2). Control experiments without redox polymer showed no current response. This demonstrates the efficiency of the osmium-based mediator in electron transfer between the cells having a thick cell wall and the electrode. The findings have significant importance in microbial electrochemistry for further understanding of microbe-electrode interactions. (C) 2016 Elsevier B.V. All rights reserved.
