| Outline of Annual Research Achievements |
The electrochemical reactor systems currently used for current production and drug testing involve relatively large volumes, making these systems infeasible for high-throughput screening of potential antimicrobials. We used screen-printed electrodes or multi-well electrode systems that require minimum amounts of sample and antimicrobials. Such systems that exploit the electrogenic activity of pathogens could fast-track the discovery of antibiofilm drugs, as a large library of compounds could be rapidly screened. This concept could serve as a generally applicable technology for evaluating the efficacy of antimicrobials, as well as the selection of appropriate drugs or treatment regimens. Our works extended the boundaries of EET field to other niches such as human pathogens. The orthologues of the identified EET genes in human pathogens are present in hundreds of species, thus EET activity likely occurred in an evolutionarily diverse subset of bacteria. Consequently, our research can help screen the effects of antimicrobials on biofilm activity by employing the current producing capability in wide range of electroactive pathogens.
