Tuberculosis is caused by bacteria. Specifically, the bacterium Mycobacterium tuberculosis is responsible for the disease, which primarily affects the lungs but can also impact other parts of the body.
Leghemoglobin functions in nitrogen fixation by absorbing oxygen. It creates a low-oxygen environment in the root nodules, which is necessary for the nitrogen-fixing enzyme nitrogenase to function effectively and fix atmospheric nitrogen.
Beans are helpful in nitrogen fixation. They form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into a form usable by the plant and enriching the soil.
If one bacterial cell divides every 20 minutes, it will divide six times in two hours (120 minutes). Since each division doubles the number of bacteria, the original cell will result in 2 power 6 = 64 bacteria. Therefore, the ...
Antibiotics are mostly obtained from bacteria and fungi. These microorganisms naturally produce antibiotics to inhibit the growth of competing bacteria and other microbes. Some well-known antibiotics, such as penicillin, are derived from fungi.

The bacteria found in the human intestine is Escherichia coli. It is a common and normally harmless bacterium that is part of the gut flora. It aids in digestion and synthesizes certain vitamins for the human body.
Bacteria are not able to survive in pickles with excess salt because their protoplasms get shrunk due to osmotic pressure, leading to dehydration and death. This process, called plasmolysis, inhibits bacterial growth and preserves the pickles.
