A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming.
In a paper published on Dec. 6 in the prestigious science journal Nature, U of C biology professor Peter Dunfield and colleagues describe the methane-eating microorganism they found in the geothermal field known as Hell’s Gate, near the city of Rotorua in New Zealand. It is the hardiest “methanotrophic” bacterium yet discovered, which makes it a likely candidate for use in reducing methane gas emissions from landfills, mines, industrial wastes, geothermal power plants and other sources.
“This is a really tough methane-consuming organism that lives in a much more acidic environment than any we’ve seen before,” said Dunfield, who is the lead author of the paper. “It belongs to a rather mysterious family of bacteria (called Verrucomicrobia) that are found everywhere but are very difficult to grow in the laboratory.”
