A teaspoon of productive soil generally contains between 100 million and 1 billion bacteria. They can be classified according to the functions they perform in soil and are: Nitrogen-fixing bacteria form symbiotic associations with the roots of legumes like clover and lupine, and trees such as alder and locust. Visible nodules are created where bacteria infect a growing root hair. The plant supplies simple carbon compounds to the bacteria, and the bacteria convert nitrogen (N2) from air into a form the plant host can use. When leaves or roots from the host plant decompose, soil nitrogen increases in the surrounding area. Nitrifying bacteria change ammonium (NH4+) to nitrite (NO2-) then to nitrate (NO3-) - a preferred form of nitrogen for grasses and most row crops. Nitrate is leached more easily from the soil, so some farmers use nitrification inhibitors to reduce the activity of one type of nitrifying bacteria. Nitrifying bacteria are suppressed in forest soils, so that most of the nitrogen remains as ammonium. Denitrifying bacteria convert nitrate to nitrogen (N2) or nitrous oxide (N2O) gas. Denitrifiers are anaerobic, meaning they are active where oxygen is absent, such as in saturated soils or inside soil aggregates. Actinomycetes are a large group of bacteria that grow as hyphae like fungi . They are responsible for the characteristically "earthy" smell of freshly turned, healthy soil. Actinomycetes decompose a wide array of substrates, but are especially important in degrading recalcitrant (hard-to-decompose) compounds, such as chitin and cellulose, and are active at high pH levels. Fungi are more important in degrading these compounds at low pH. A number of antibiotics are produced by actinomycetes such as Streptomyces.
Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.
Earthworms, fungi, and bacteria are three common living organisms found in soil. Earthworms help improve soil structure, fungi decompose organic matter, and bacteria play a vital role in breaking down nutrients for plants to absorb.
There can be billions to trillions of bacteria in 1 gram of sandy soil, depending on various factors such as soil composition, moisture content, and nutrient availability. Bacteria play a crucial role in soil health and ecosystem functioning.
Bacillus subtilis is a common bacteria found in soil and dust due to its ability to form spores that allow it to survive in harsh conditions. It is known for its role in breaking down organic matter and recycling nutrients in the environment.

Tetanus is caused by a common bacteria found in the soil. It can be contracted by the bacteria entering the body from a wound. Such as stepping on a rusty nail.
There are many decomposers in the estuaries of rivers. The majority of these are different types of bacteria and fungi. They enrich the water and soil with recycled organic matter.
Some common bacteria that can live in soil or water include Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis. These bacteria have adapted to thrive in diverse environments and play important roles in nutrient cycling and decomposition.
Common names for germs include bacteria, viruses, fungi, and parasites. Examples of specific germs include E. coli (bacteria), influenza (virus), Candida (fungus), and Plasmodium (parasite causing malaria).
The common name for Eubacteria and Archaebacteria both is bacteria. The scientific names are Eubacteria/Bacteria and Archaebacteria/Archaea.
Nitrogen is the most common one.
Some common names for bacteria that live in water include cyanobacteria, heterotrophic bacteria, and nitrifying bacteria. These bacteria play essential roles in the aquatic ecosystem by participating in nutrient cycling, decomposition, and overall water quality maintenance.
The most common prokaryotic organisms are bacteria. They are found in various habitats on Earth, such as soil, water, and the human body. Bacteria play important roles in nutrient cycling, decomposition, and symbiotic relationships with other organisms.
