Extracellular electron transfer pathways to enhance the electroactivity of modified Escherichia coli

Ardemis Anoush Boghossian, Nils Schürgers, Melania Reggente, Mohammed Mouhib

Escherichia coli (E. coli) show limited extracellular electron transfer (EET) that compromises their use in bioelectronics. We enhance the EET in E. coli by expressing an electron transfer pathway that spans the inner and outer membranes of the cell, inclu ...
