Analysis of mature biofilms in microbial fuel cellsa
| Strain | Substrate coverage (%) | Thickness (μm) | Roughness | Maximum thickness (μm) |
|---|---|---|---|---|
| Wt (DL100) | 67 ± 7 | 44 ± 4 | 0.26 ± 0.07 | 55 |
| Short isoform (pilA4) | 38 ± 12 | 47 ± 13 | 0.49 ± 0.08 | 72 |
Biofilms were grown on graphite anodes poised at +300 mV (vs. Ag/AgCl) after 3 days at maximum current. The values are averages of triplicate samples ± standard deviations.
