Accelerated climate change is a major and acute threat to life on Earth. Rising temperatures are caused by microbes producing 50% of atmospheric methane which is 30 times more potent than CO2 at trapping heat. These elevated temperatures are also accelerating microbial growth and thus producing more greenhouse gases than can be used by plants. This weakens the Earth’s ability to function as a carbon sink and further raises the global temperature.
The Malvankar lab had previously reported that this protein wire shows the highest conductivity known to date, allowing bacteria to produce the most electric power reported so far, and explaining how these bacteria can survive without oxygen-like membrane-ingestible molecules. To date, no one had discovered how they are made or why they are so conductive.
Using high-resolution cryo-electron microscopy, the researchers were able to see the nanowire’s atomic structure. They discovered that hemes were packed closely to move electrons extremely quickly with great stability. The team also built some nanowires synthetically to explore how bacteria make nanowires on demand.
“It is possible we could use these wires to generate electricity or understand how methane-eating microbes use them to combat climate change,” Malvankar said.
