Microbes that break down oil and petroleum are more diverse than we thought, suggesting hydrocarbons were used as an energy source early in Earth's history, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin. These microbes can change the composition of oil and natural gas and can even control the release of some greenhouse gases. Understanding the role of microbes in consuming hydrocarbons may therefore help us access their role in the natural control of climate change.
