Bacteria That Eat Toxins and Produce Energy

What’s new

A group of scientists from Washington State University  found communities of bacteria in Yellowstone hot springs that can feed on toxic substances and generate energy.

How They Discovered Them

Several electrodes were  installed at the edge of a hot spring. When they retrieved them 32 days later, they found entire communities of bacteria feeding on the carbon surface of the instruments. In the process, the bacteria pass their electrons to the other surface through small protuberances that function like wires, producing electricity.
