Endocrine disruptive estrogens role in electron transfer: Bio-electrochemical remediation with microbial mediated electrogenesis

► Estrogens removal through a combination of biochemical and electrochemical activity. ► Estrogens functioned as electron shuttler between biocatalyst and anode. ► Natural estrogen (E3) removal is higher than synthetic estrogen (EE2). ► Increasing estrogen concentration has toxic influence on the biocatalyst function. ► Estrogens helped in overcoming electron losses and enhanced power generation to certain extent.
