How Do We Sense Smell? Bacteria, also called germs, are microscopic organisms not visible with the naked eye. Bacteria are everywhere, both inside and outside of your body. Bacteria can live in a variety of environments, from hot water to ice. Some bacteria are good for you, while others can make you sick. Bacteria are single-celled, or simple, organisms. Though small, bacteria are powerful and complex, and they can survive in extreme conditions. Bacteria have a tough protective coating that boosts their resistance to white blood cells in the body.
Some bacteria have a tail, called a flagellum. The flagellum helps a bacterium to move around. Other bacteria have sticky hair-like appendages that help bacteria them stick to one other, hard surfaces, and human body cells. There are many bacteria in the human body, especially in the stomach and mouth.
Bacteria are found on surfaces and in substances such as water, soil, and food. Bacteria can be aerobic, anaerobic, or facultative anaerobes. But it is the living processes that bacteria use and the wastes they give off that can be used either for human benefit or that cause disease. Scientists believe it was the chemical processes of early cyanobacteria, harnessing the energy from the sun, that released the oxygen that makes up our atmosphere.
It took approximately 2 billion years for the bacteria to build up enough oxygen in the atmosphere to allow for the evolution of multi-cellular organisms. Bacteria have long been used by humans to create food products such as cheese, yoghurt, pickles, soy sauce and vinegar.
We are also able to use bacteria to break down our sewage and to clean up oil spills. Many bacteria are very fast growing — under ideal conditions, Escherichia coli E. Coli are able to double their number in 20 minutes.
