Abstract: The global warming is attributed to greenhouse gases including methane gas, produced naturally and by human activities. Such gases trap heat, causing Earth fever. It is witnessed by continuous increases of such gases in the atmosphere by glacier retreating, collapsing ice shelves, melting of ice and snow, increasing precipitation, rising of seal level and changes in flora and fauna habitats. Methane is known to affect the ozone layer 20-30 times the effect of carbon dioxide and is increasing. Presently, Earth’s atmosphere contains 5 ppm methane and increasing. Sources of methane, like soil over subterranean hydrocarbons all over the world, rice fields, swamps and the like could be limited by growing a special methane oxidizer, methanomonas methanoxidans such surfaces. In our research, we have found that this bacterium will consume over 8.5 L of methane per square meter per day and continued steadily for the 4 month period studied. Consumption of methane was nearly the same using the potting soil and soil-sand mixture, whether natural or sterilized. When bacterial flora persisting in potting soil with the Methanomonas sp were isolated and added (107 cells/g soil) there was no effect of consumption of methane by the Methanonomanas sp. Natural elements in soil remained adequate before and after growth period of 4 months. Viability and consumption of methane at different temperatures is still under study. We would like to extend the project by studying the effect of seasonal fluctuations in temperature on viability and methane consumption at different season.
