What are some features of bacteria?

bacteria are microbes, usually 0.0000196 to 0.00019 inches (0.5 to 5.0 micrometers) in length, which can be found in huge numbers in each part of the environment, from at least 2 miles (3.2 km) underground to 7 miles (11.2 km) above the earth's surface. They colonize areas uninhabitable to most other life forms, including Yellowstone Hot Springs and McMurdo Dry Valleys of Antarctica.

Human beings also have a huge number of bacteria in the body and on their bodies. It is estimated that there are about ten bacteria for each cell in the human body, a total of approximately 1 quadrillion (10

) microbes, distributed between 500 and 100,000 species. The vast majority live in the large intestine, although they can be found throughout the body. Some of the bacteria in the body are good, like lactobacillus , which converts milk protein into lactic acid in the intestine and some are bad, like Bakets responsible for dental caries and stomach ulcers.

bacteria are found in fertile soil in huge quantities: approximately 100Millions to 3 billion per 0.035 ounce (1 gram) soil, sometimes with up to a million species in this small sample. Although only a few species are dominated by a typical sample of the soil, there are a large number of present, but in low abundance. They help other organisms to decompose organic detritus and create rich soil. In particular, bacteria are the only form of life capable of converting atmospheric nitrogen into fixed (solid) nitrogen in the form of nitrates, which then use plants as nutrients.

If there is an organic material present or even, in some cases inorganic reduced compounds, then bacteria in cooperation with other microorganisms are likely to find some way to spend it. There are species that consume pieces of tires on the side of the road, dissolve Alzheimer plaques in the corpses and even consume TNT or sulfate minerals. USA bacteria or other microbes for decomposing toxic chemicals is called Bioremmediation.
