Examples Of Good Bacteria

Bacteria are single-celled organisms, invisible to the naked eye. The famous naturalist Stephen Jay Gould wrote in his article “Planet of the bacteria” that bacteria were responsible for all life on Earth for the first two billion years life existed here. They still account for more than half of the biomass (living things by weight) of life on Earth today. Bacteria can transfer cruel diseases (like the plague), but they can also be beneficial to humans.
Digestion
You have billions of bacteria in your body right now. According to famous German microbiologist Robert Koch, they account for about 10 percent of your total body weight. Most of these bacteria live in the gastrointestinal tract and is favorable. They are essential for digestion, and also helps in the production of vitamin K, which people need, but can not produce without bacteria. Bacteria also help in the process of rebuilding the stomach and intestinal lining, which is becoming destroyed by digestive juices. You can get an idea of ​​how abundant bacteria in the digestive system by recognizing that 95 percent of our fecal matter is composed of dead bacteria. This level of mutually beneficial cooperation, it has been because people and our “guest” bacteria have been co-developing for millions of years.
Food
Some bacteria have an amazing effect on milk. They convert lactose-the primary sugar in milk into lactic acid. This makes the milk acidity, which kills all bacteria and prevents further penetration of bacteria into the milk, the bacteria can not exist in an acidic environment. From a nutritional standpoint, this process provides a wide variety of healthy, delicious and high-protein foods, such as cheese, yogurt, kefir, sour cream and buttermilk. Bacteria also play important roles in the treatment of other foods such as chocolate and coffee. Bacteria are not important in the fermentation of alcoholic beverages (yeast is not bacteria), but they are often an important element of flavor.
recycling
If it were not for bacteria, the world would be much more dangerous (and disgusting). Bacteria are the main forces acting on the bodies of dead plants and animals as they decompose. Bacteria are instrumental in how nature recycles organic material, as well as in recycling valuable nutrients. Nitrogen, a component of amino acids that are the building blocks of proteins, is an essential element for all living things. Too much nitrogen would stay fixed in the soil, were it not for “nitrogen-fixing” bacteria that helps plant roots extract nitrogen.
