Porins

• We heterologously expressed the porin protein OprF from Pseudomonas fluorescens into Escherichia coli. This leads to dramatically increased membrane permeability and a much higher current output in comparison to its parental strain (E. coli KRX) caused by improved electron shuttle-mediated extracellular electron transfer. The heterologous expression of outer membrane porin OprF from Pseudomonas fluorescens in Escherichia coli is a great genetic strategy to improve electricity generation by microorganisms.
