"We were surprised that we did not find methanogenic bacteria that produce methane at Lost Hammer," Whyte said, "but we did find other very unique anaerobic organisms - organisms that survive by essentially eating methane and probably breathing sulfate instead of oxygen."

Then methanogenic bacteria metabolize these compounds into a combination of methane-rich gas and an odorless phosphorus- and nitrogen-laden slurry, which makes excellent fertilizer.
