New Microbe Strain Makes More Electricity, Faster

In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than earlier strains, cutting the time to reach electricity-producing concentrations on the electrode.

  1. Thanks for posting this Betsy. I know Lovley has been working with Geobacter for a long time now, perhaps 10 years. It's interesting to see that they are tinkering with the microbes genetic make up to make it more efficient and powerful. I'm waiting for the day I can carry around a microbial fuel cell powered iPhone :)
