AB This study seeks to assess the impact that the anodic electrodeposition of graphene oxide (GO) hason the start-up process and on the development of microbial communities on the anode of BESs.The GO electrodeposited electrodes were characterised in abiotic conditions to verify the extent ofthe modifcation and were then transferred to a bioelectrochemical reactor. Results showed thatthe modifed electrode allowed for a reduced start-up time compared to the control electrode. Afterthree months, high throughput sequencing was performed, revealing that electrochemically reducedgraphene oxide acts as a selective agent toward exoelectrogenic bacteria as Geobacter. Overall, thisstudy shows that GO modifed electrodes enhance bioflm build up in BES.
