Gas-Guzzling Bacteria

I found an interesting article while surfing, about bacteria that oxidize methane and can reduce the amount of methane in soils (http://www.brightsurf.com/news/headlines/17905/Gas-guzzling_bacteria.html). Under atmospheric conditions in well-drained soil, the bacteria can reduce methane in soil by 10 percent.

The bacteria was detected using a new method involving stable carbon isotopes and allows scientists "to track where carbon is incorporated into bacteria at the low atmospheric levels of methane in soils."

The bacteria can be used to maximize the amount of atmospheric methane oxidized by soils, and may help deal with the increased level of methane in our atmosphere today.
