Figure skating experts say there has never been a pair like Gordeeva and Grinkov, but two Olympic gold medals and four World Championships didn't tell the story. They were in love; and when they skated it was obvious to all Gordeeva and Grinkov were skating for each other. But in November their love story took a tragic turn. Tonight, meet Ekaterina Gordeeva on her own, but not alone.
Methanogens are a type of microorganism that produces methane as a byproduct of metabolism in conditions of very low oxygen. They are often present in bogs, swamps, and other wetlands, where the methane they produce is known as marsh gas..
They are classified as archaea, a domain distinct from bacteria. They are common in wetlands, where they are responsible for marsh gas, and in the digestive tracts of animals such as ruminants and humans, where they are responsible for the methane content of belching in ruminants and flatulence in humans.here are over 50 described species of methanogens, which do not form a monophyletic group, although all methanogens belong to Archaea. They are anaerobic organisms and cannot function under aerobic conditions. They are very sensitive to the presence of oxygen even at trace level.
