Correction to: Modification of carbon felt anode with graphene/Fe₂O₃ composite for enhancing the performance of microbial fuel cell (Bioprocess and Biosystems Engineering, (2020), 43, 3, (373-381), 10.1007/s00449-019-02233-3)

It has been brought to our attention that in our article, explanations about cable bacteria are not rigorous. We apologize for these and note the specific reporting issues and errors below, with their corrections: Abstract, “promote the cable bacteria formation and enhance electron transport efficiency over long distances” Should be change to: “promote the exoelectrogenic bacteria formation”. Bacterial community structure of biofilms in MFCs, the paragraph 2: “Desulfovibrio has been reported to be cable bacteria [35], which was filamentous bacteria that transport electrons across distances of several centimeters and connect spatially separated electron donors and acceptors [36]”. Should be change to: “Desulfovibrio has been reported to be exoelectrogenic bacteria [35, 36], which may also transfer electrons to the electrode”. This has no impact on the conclusions of the paper. The authors would like to apologize for any inconvenience caused.
