Antibacterial effect of copper nanoparticles produced in a Shewanella-supported non-external circuit bioelectrical system on bacterial plant pathogens.

ABSTRACT: The use of copper nanoparticles for the inhibition of plant pathogens Ralstonia solanacearum, which causes wilt disease, and Xanthomonas axonopodis, which causes citrus canker, was investigated in this study. To avoid the inhibiting effect of Cu²⁺ ions on the bacterial cells, the copper nanoparticles were synthesized in the cathode chamber of a non-external circuit bioelectrochemical system (nec_BES) inoculated with Shewanella sp. HN-41 at the anode. The electrons produced by the oxidation of lactate by Shewanella sp. HN-41 were directly transferred to the anolyte in the cathode via a graphite electrode connecting the anode and cathode chambers. SEM images of the produced particles revealed that the copper nanoparticles were aggregated into sph
