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..
There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants.Ancient methanogens are the source of natural gas. Halophiles are bacteria that thrive in high salt concentrations such as those found in salt lakes or pools of sea water.Thermophiles are the heat-loving bacteria found near hydrothermal vents and hot springs.ncient methanogens are the source of natural gas.
