Methane-Eating Bacteria Could Combat Global Warming

realwx writes "New Zealand scientists have found a bacterium, named 'Methylokorus infernorum,' that eats a key global warming chemical. Found in a hot spring, the bug lives off of methane emissions from geothermically active areas. A scientist quoted in the article stated that a cubic meter of liquid containing the bacterium would consume about 11kg of methane each year. 'But Dr Stott cautioned that such an application was probably some years into the future. He said it was unlikely the micro-organism, which prefers acidic conditions of about 60C, could ever be added to sheep or cows' food to stop the animals releasing methane.'"

      Methane has a much greater effect on the atmosphere than carbon dioxide, I'm told. If you burn methane, however, you get carbon dioxide and water, so it seems that the solution to the problem is to collect and burn the methane. For bonus points, you also get energy.

      As I see it, the problem is that the cycle is carbon dioxide to long chain hydrocarbons in plants then animals to methane. If you burn the methane, you create a closed cycle, which has no net effect on the atmosphere (you put back the same amount of carbon dioxide you remove). Sequestering methane makes a lot less sense than sequestering carbon dioxide, since you can't easily get energy out of carbon dioxide.

Moreover, cows eat grass on rangelands where the land can't support growing crops and if it could there's no water. So every calorie you get from that is one you never could get from a vegetable.
