Why are bacteria and other microorganism used to fight pollution?

Bacteria have an amazing ability to adapt to almost any food source. Scientists expose bacteria to soils rich in various pollutants and eventually one or more decide they can use it as food and multiply. The scientists culture this bacterial strain until they have marketable quantities then sow them into contaminated soil at a spill or other polluted site. The bacteria eat at the contamination until it is all gone.
In sewage treatment plants bacteria have been eating waste water contaminants for years, Normal bacteria eat sewage but in industrial waste there are often organic poisons that would kill normal microbes. They adapt however and eventually are happily eating phenols and oils. Refineries often swap bacterial colonies to meet start-up colonization of their treatment systems.

Medicines used to kill bacteria and other microorganism?
The medicines used to kill bacteria are generally called antibiotics. Penicillin is a typical famous example.
What cant teeth do that other body parts can do?
teeth can not fight off of those bacteria and infection
How do microorganisms produce energy to stay alive?
This depends on what microorganism. Some microorganisms, like microscopic plants and some bacteria, are autotrophic (specifically phototrophic), meaning they create their own energy using (mainly) water and sunlight. Other microorganisms, like some bacteria and fungi, are heterotrophic, meaining they consume other organisms to get their energy.
Do microorganism grow in dry conditions?
This will depend upon the specific microorganism you are asking about. Many common human pathogens, such as E. coli and Salmonella, do not grow at all below a water activity level of about 0.95. However, there are some bacteria that tolerate extremely dry conditions and can grow in places like the Sahara Desert, in the bottom of the Salt Lake in Utah and in other harsh conditions.
Is bacteria contageous?
Actually, this is a very good question. When we look at the definition of pathogenic, we know that disease causing microorganism are pathogenic. Is E.Coli a disease causing microorganism? Well, E .coli can be found in uncooked foods, feces and in other unsanitary conditions. If the E.coli found in any of these conditions are consumed, we have a very serious problem. However, what about the E.coli that is inside of our large intestine helping synthesize vitamin K. These guys are not pathogenic. When answering questions of whether bacteria are pathogenic we must always consider the strain. The strain tells us the pathogenic status of the bacteria and will even tell us the degree of pathogenicity.

An antiseptic is a substance used to?
It is any chemical substance, that kills harmful bacteria, or other microorganism's, on the surface of objects, so as to protect the handler of those objects from infections caused by those microorganism's.
Why are parks important?
They help in the fight against pollution and also provide a sanctuary for other animals.
What are the similarities between gram positive and gram negative bacteria?
what are the similarities of the negative gram and positive gram? both will only relate to the bacterias but not any other microorganism.
What is a skin culture?
A skin culture is a test that is done to identify the microorganism (bacteria, fungus, or virus) causing a skin infection and to determine the antibiotic or other treatment that will effectively treat the infection.
Is there more than one type of pathogen?
Yes, there are possibly millions of kinds of pathogens. "Pathogen" simply meansany disease-producing agent, especially a virus, bacteria, or other microorganism.
What cant teeth do that other body parts can do?
teeth can not fight off of those bacteria and infection
Is the water in Loch Ness drinkable?
No not unless it is purified. No lake water is drinkable due to pollution, bacteria in the water, and other conditions.
What are the useful and harmful effects of microorganism?
Some microorganisms are part of the body's natural processes. For instance, the bacteria of your digestive tract help you to digest food. Other microorganisms can cause disease. Some otherwise beneficial bacteria can be harmful if they become too abundant.
Are people bacteria or germs?
Germs are any pathogenic (disease causing) microorganism. These might be bacteria, or they might be other things. Bacterial cells lack a nucleus. Humans are eukaryotes, whereas bacteria are prokaryotes. So people are not bacteria. People are multicellular, whereas germs are generally considered to be single celled orgamisms (most typically bacteria) or viruses. In that sense people are not germs either.
Is a cell a microorganism?
All microorganisms except viruses are comprised of cells. Viruses are incomplete cells. Other microorganisms are either one-celled (prokaryotic) or comprised of small clusters of cells (simple eukaryotic).
Everytime you have a blood test your wbc is always high what could be the problem?
blood testour wbc is the defense or what we called the soldiers of our body they fight microorganism that enter our body, that is why in a laboratory exam that shows a high wbc count means an infection is presence.so it means that it is our bases to know if a foreign bodies enter our body. As we do our blood test we need to use syringes to extract blood and the needle of this syringes need to be inserted in our skin and to oue veins, so therefore the needle the is use to extract the blood have or contain something that maybe a bacteria, virus or other microorganism which we can.t see, that is why as the needle enter our body the microorganism almost enter our body especially when blood test because the organism may directly goes to our circulatory system. And if this happen our wbc need to defend our body that is why it needs to increase in number in order to won the fight against the invading microorganism
