As bacteria convert greenhouse gases into useful products?
The so-called "greenhouse effect" plays an important role in the evolution of life on our planet. Greenhouse gases that make up the earth's atmosphere, practically impermeable to heat radiation, thereby creating a number of problems causing climate change. Excessive heating of the atmosphere caused by the anthropogenic impacts on the environment, leading to global warming, which may gradually transform our planet into a place very similar to Venus. In order to prevent such a transformation is not the most pleasant thing, scientists have found a way to convert greenhouse gases into useful chemical compounds using bacteria E. coli.
E. coli can help reduce emissions of carbon dioxide in Earth's atmosphere
What are greenhouse gases?
Earth's atmosphere protects our planet from harmful solar radiation and gives living beings to breathe, contains a huge variety of gases, among which a special place is occupied by methane, ozone, water vapor and carbon dioxide. The mixture of these gases keeps the solar heat, thereby maintaining a favorable climate for living beings on the surface. However, according to recent research scientists, the concentration of greenhouse gases is currently much higher than at any time in the past 800,000 years. Greenhouse gases, in addition to climate change, influence the development of respiratory diseases due to rising levels of air pollution. In the future, changing climate may lead to large-scale extinction of some species. There are several types of greenhouse gases significantly affect the Earth's atmosphere. Carbon dioxide or carbon dioxide - a representative of greenhouse gases, which accounts for about 64% of environmental changes associated with global warming. The main source of carbon dioxide to a oil-producing, refining and gas industry.

E. coli can transform a greenhouse gas into a useful substance
The newest technique is based on the human enzyme that converts one-carbon compounds into more complex. Scientists make changes in the DNA structure of rod-shaped bacteria Escherichia coli, using the modified enzyme. After all modifications introduced into E. coli feedstock, as is most often used, methanol, formaldehyde, carbon dioxide and methane. Ultimately, the feedstock starts to occur metabolic bioconversion process in which molecules are converted to more complex compounds.
For manufacturers of oil this discovery can be attractive and cost-effective method for recycling the carbon dioxide, because the complex compound formed during the bioconversion process may be used in the production of plastics, polymers and cosmetics. Scientists believe this result breakthrough in the biological conversion of carbon dioxide, through which may turn out to reduce the amount of greenhouse gases emitted during the production of crude oil.
Using the method of bioconversion will help reduce greenhouse gas emissions and total dependence on oil
By implementing a new technology, the oil industry could significantly reduce the impact on the environment. Until now, the vast majority of the oil industry uses the method of burning gas released during oil production. Many believe that this method is wasteful and inefficient, and leads to the release into the atmosphere the excess unburned methane and carbon dioxide formed during combustion.

At the moment, scientists are working on the introduction of the latest bioconversion technology, not only in the private sector, but also in the entire refining industry as a whole, which subsequently have a significant impact on the environment and help reduce the impact on the Earth's atmosphere.
