Microbes turn electricity directly to methane
Date: 4.4.2009
A tiny **microbe** can take **electricity** and directly convert carbon dioxide and water to **methane*, producing a **portable energy** source with a potentially neutral carbon footprint, according to a team of Penn State engineers.
**Methanogenic** microorganisms do produce methane in marshes and dumps, but scientists thought that the organisms turned hydrogen or organic materials, such as acetate, into methane.
