How might microbes be able to help reduce greenhouse emissions and role of microorganisms in production and utilization of greenhouse gases?
Soil microbes such as growth-promoting bacteria and fungi have proven to sequester carbon into the soil. Through this process, microbes are able to reduce atmospheric carbon dioxide and therefore can be utilized to tackle the issue of climate change. Microbes are involved in many processes, including the carbon and nitrogen cycles, and are responsible for both using and producing greenhouse gases such as carbon dioxide and methane. Microbes can have positive and negative responses to temperature, making them an important component of climate change models. While some microbes are beneficial to curbing climate change serving as major drivers of elemental cycles or consuming greenhouse gases, like methane and carbon dioxide others may contribute to rises in methane, carbon dioxide or nitrous oxide in the environment. Photosynthetic microbes consume atmospheric carbon dioxide, whereas the heterotrophs decompose organic matter to emit greenhouse gases. The balance between the two processes is the main determinant of the net carbon flux, which differs across various ecosystems, depending upon climatic conditions like temperature.
Microbes are involved in many processes, including the carbon and nitrogen cycles, and are responsible for both using and producing greenhouse gases such as carbon dioxide and methane. Microbes can have positive and negative responses to temperature, making them an important component of climate change models. Microorganisms in terrestrial, urban, and aquatic environments consume and generate important greenhouse gases, CO2, CH4, and N2O. Terrestrial microbes decompose organic matter, providing nutrients for plants and producing these three gases. Beneficial microbes such as rhizobacteria and mycorrhizal fungican help plants to 'deal' with pathogens and herbivorous insects as well as to tolerate abiotic stress. Microorganisms produce several compounds that have potential for enhanced oil recovery, including carbon dioxide, acids, and alcohols. Carbon dioxide may increase reservoir pressure and decrease the viscosity and gravity of the crude oil, allowing it to move more freely to the producing wells. Microbes play an important role in climate because they release carbon dioxide into the atmosphere when they eat. Bacteria and their main predators, protists, account for more than 40 times the biomass of all animals on Earth. As a result, they have a huge effect on carbon dioxide emissions. Accumulation of greenhouse gases in the atmosphere – from the burning of fossil fuels and deforestation – lead to a heating of the earth's surface. This in turn leads to impacts such as shifting seasons, rising sea-levels, disappearing Arctic sea-ice and more intense heat waves. Earth's greenhouse is also full of plants! Plants can help to balance the greenhouse effect on Earth. All plants from giant trees to tiny phytoplankton in the ocean take in carbon dioxide and give off oxygen. The ocean also absorbs a lot of excess carbon dioxide in the air.
Biological methane production is only done by microorganisms. The current estimates suggest that 90–95% of the methane released into the atmosphere has a biological origin and is produced exclusively as a result of microbial activity. Microbes in terrestrial environments are important catalysts of global carbon and nitrogen cycles, including the production and consumption of greenhouse gases in soil. Some microbes produce the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) while decomposing organic matter in soil.

Biogas is the mixture of gases produced by microorganisms. It is a renewable source of energy. Methane is the predominant gas present in the biogas mixture. Certain bacteria grow under anaerobic conditions and produce a large amount of methane along with carbon dioxide and hydrogen.
