Fluorescent probe based subcellular distribution of Cu(II) ions in living electrotrophs isolated from Cu(II)-reduced biocathodes of microbial fuel cells
Electrotrophs were isolated from Cu(II)-reduced biocathodes of microbial fuel cells. Cu(II) removal rates of 2.90–3.64 mg/L h were achieved by these electrotrophs. Fluorescent probe was used to successfully track Cu(II) ions in electrotrophs. Cathodic electrons directed more Cu(II) ions for quicker entrance into cytoplasm.
