Increasing intracellular releasable electrons dramatically enhances bioelectricity output in microbial fuel cells

Microbial fuel cell (MFC) is a sustainable energy source that can harvest electricity energy from organic wastes. However, its low electricity output remains the bottleneck for practical applications. Herein, we report a novel approach to increase extracellular electron transfer between bacteria and...

However, its low electricity output remains the bottleneck for practical applications. Herein, we report a novel approach to increase extracellular electron transfer between bacteria and anodes, thus enormously enhancing the bioelectricity output in MFCs. We find that the abolishment of the lactate synthesis pathway increases intracellular releasable electrons, which are subsequently transferred to the anode via a secreted diffusive electron shuttle. Thereby, such genetically modified strain delivers a much higher and more stable electricity output than its parental strain in MFCs. 2013-07-01T07:36:10Z 2019-12-06T20:03:55Z 2013-07-01T07:36:10Z 2019-12-06T20:03:55Z 2012 2012 Journal Article Yong, Y.-C., Yu, Y.-Y., Yang, Y., Li, C.
