Three kinds of BCRC No.51534, 10322 and 10675 would be selected and acted as an experimental sample of Escherichia coli. Results shows that Escherichia coli of No.51534 will appear better performance because the maximum of open circuit voltage, closed current and power density are 1.01V, 22mA and 1342mW/m2, respectively. Concerning the effect of culture time with respect to different phase type on the electricity performance of MFCs, the time points on the intersection between lag phase and logarithmic phase, the middle of point of stationary phase for growth curve of Escherichia coli would appear a good performance of MFCs. In addition, the BCRC No. 51534 Escherichia coli possessing a better performance of MFCs than others would be suggested and applied to further studying.

Finally, the effect of molar concentration on the performance of MFCs would be expected at the studied cases of 0.4M, 0.2M, 0.1M and 0.05M respectively for cathode oxidant, result shows that a good performance of MFCs will happen at the condition of 0.2M. Those observations will be useful to improvement of MFCs in the further study.
