Humans use nitrogen in the form of proteins. Bacteria found in soil convert atmospheric nitrogen into nitrates that plants use to produce proteins.
There are some bacteria which helps in producing nitrogen and the phenomenon is called denitrification in which nitrate is converted in inorganic nitrogen they are: pseudomonas, micrococcus, thiobacillus etc.
Bacteria are involved in decomposing materials.
These bacteria, through the plant, receive elemental nitrogen from the air, and use it to produce ammonia (NH3). This process is called nitrogen fixation. The ammonia can then be converted in to oxides of nitrogen and nitrogen salts, such as nitrites and nitrates, which are used by the host plant and others as nutrients.
Nitrogen-Fixing bacteria. aka Rhizobium
Bacteria is used for 5 major reasons. Reason 1- Nitrogen fixing bacteria consume nitrogen in the air and change it into a form that plants can use. Reason2-By breaking down dead organic matter, decomposing bacteria make nutrients available again to living things. Reason3-Recently bacteria have been used to combat pollution. Reason4-Antibiotics are medicines used to kill bacteria and other microoroganisms. Reason5-Sientist have created genetically enginerring bacteria that can produce other medicines such as insulin for diabetics. Reason 6-People breed bacteria for food. The lactics-acid bacteria act as preservations and adds flavor to those foods.
How are some ways that bacteria can be beneficial?1. Some bacteria in your intestines are responsible for producing Vitiman K, which is necessary for normal blood clot formation.2. Some bacteria produce antibiotics that help limit the growth of other harmful bacteria.3. Consumer bacteria called, saprophytes, help mantain natures balance by decomposing waste.4. Nitrogen-Fixing Bacteria change nitrogen from the air into forms that plants and animals can use easily.
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.
Bacteria Certain bacteria can use nitrogen from the air to make nitrogen-containing substances called nitrites. Other bacteria can turn nitrites into nitrates-another group of nitrogen-containing substances.
Bacteria are essential to the nitrogen cycle.
because when bacteria convert ammonia into nitrates and nitrites, producers need them to make proteins, and then consumers eat the producers and reuse the nitrogen to make their own proteins.
Although the air is made up of about 80% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle
