Figure 9： Among optimized shewanella, shewanella+MG1655 and Shewanella+ΔplfB ldhE+Rf02S, the three-strain coculture system reached a relatively higher potential that kept around 350 mV in 80 hours.

Conclusion: Shewanella+ΔplfB ldhE+Rf02S has been going through a preferable optimization. It led to the potential of 300 mV in 80 hours under the condition of 2 g/L glucose without any supplementary. So, it realized a higher and more endurable power generation when taking glucose as carbon sources in Shewanella.

Figure 10： The potential and time of duration in Shewanella+ΔplfB ldhE+B.Subtilis system can be raised into 511 mV and 80 h, respectively, resulted in a greater generation amount.

Figure 11：

The potential produce by Shewanella+ΔplfB ldhE+B.Subtilis is greater than Shewanella+ΔplfB ldhE+Rf02S for 176 mV. Cocultured Shewanella, E.coli and B.subtilis can achieve a better job division that can reduce the competition between two kinds of zymophyte since B,subtilis can anaerobically metabolize by using KNO₃. It significantly improve the commensalism relations between three species.

(2) The relations between current density and voltage is well suited to polarization curve while the power curve can represent the relations between output power density and current density. Besides, the highest power density can reach to 17 mW/m².

The comparison of polarization curve and power curve among shewanella, shewanella+MG1655 and Shewanella+ΔplfB ldhE+B.Subtilis. We can apparently observed that the power output of Shewanella+ΔplfB ldhE+B.Subtilis is greater than the controled group.

Figure 16

The comparison of polarization curve and power curve among Shewanella+ΔplfB ldhE+B.Subtilis and Shewanella+ΔplfB ldhE+Rf02S. It has been shown in power curve that Shewanella+ΔplfB ldhE+B.Subtilis has a higher output than Shewanella+ΔplfB ldhE+Rf02S, which indicates that three-strain system can generate higher electricity and have a better MFC performance, in return, have a promising application.
