Magnetic field treatment increased electricity generation by 50% and energy efficiency by 22% in Geobacter sulfurreducens.
Plain English Summary
MF treatment significantly enhanced electricity generation and overall energy efficiency of G. sulfurreducens by 50% and 22%, respectively. The response of current to MFs was instantaneous and reversible. Cyclic voltammetry showed redox couples changed from -0.31 to -0.39 V, suggesting that MFs could alter electron transfer components. Genes for periplasmic c-type cytochromes, outer membrane cytochromes, pili, and ribosome were upregulated under MF treatment. Enhanced electron transfer was also linked to overexpression of NADH dehydrogenase I, ABC transporter, transcriptional regulation, and ATP synthase.
