Yes, Methane acts as the only source of carbon and energy for the bacteria Methanotrophs (methanophiles). Methane is a potential greenhouse gas far more potent than carbon dioxide. Methanotrophs play a major role in the reduction of the release of methane into the atmosphere from environments such as rice paddies, landfills, bogs and swamps where methane production is relatively high.
Antibiotics can wipe out our body's beneficial bacteria.
Humans have E.coli in our intestines to help us form certain vitamins. Our skin has normal flora on it that outcompete the "bad" bacteria. Plants need bacteria to fix nitrogen for them. There are many examples.
Bacteria are prokaryotes, a type of cell that lacks a nucleus, meaning bacterial DNA are not separated from the rest of the cell as is the case in eukaryotes. Animal cells, including humans, are eukaryotes.
Wetlands affect humans. It can be beneficial or not so beneficial Beneficial : wetlands are beneficial when it is drained and used for agriculture. It filters pollutants out of water and prevent soil erosion and reduce flood damage. (: I hope this helped !
Bacteria are the most abundant organisms in the world. Scientists believe that bacteria helped create the earth's atmosphere. By producing so much life-producing oxygen, bacteria eventually made the atmosphere habitable for all creatures, including humans. Bacteria are importnant to the planet as decomposers of dead organic matter, processors of nitrogen, and makers of medicine
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
Eubacteria are single celled and do not have a membrane. They can be beneficial to humans in some ways because they are capable of producing things such as cheese and yogurt.
Some bacteria are beneficial to humans. They aid in digestion, for hormonal production such as insulin for diabetes, and in generating bio fuels.
Thermophile Bacteria
Yogurt contains lactobacillus, a beneficial bacteria that digests lactose into glucose & galactose.

Bacteria produce GAS in Humans... but perhaps that isn't quite what you're wanting.But, that fact isn't particularly unrelated to one of the big products of bacteria, Methane. Many garbage dumps now have Methane powered generators, and some farms are now adding methane digesters for their waste. And many new biotechnologies now are including methane digestion.Another usage of bacteria and other microorganisms is a relatively new field of using Recombinant DNA in bacteria to produce Insulin, and other hormones or proteins for use in medicine.See Wikipedia Article:http://en.wikipedia.org/wiki/Recombinant_DNAThe advantage of producing them with bacteria include better quality control, the ability to use "human genes/human hormones&proteins" vs using those of animals which can lead to issues with allergens. And, the ability to prevent disease transmission from the use of blood products.
Two reasons, one is our lymphatic system (our immune system), and the other is the billions of other beneficial bacteria that live in and on all humans, which keep the bad bacteria at bay.
There are some bacteria that can cause intestinal disease. All humans have bacteria in their intestine but the bacteria is a good thing. One of the most prevalent bacteria in the human GI tract is E. coli. There are different strains of E. coli and not all of them are pathogenic. The bacteria inside the human GI tract is "normal Flora" and is beneficial to humans.
Cattle and other ruminants produce much more methane in their intestinal gases than humans as the intestinal bacteria digest cellulose. (Most of the gas comes out of the cow's mouth!) Methane is a greenhouse gas and bad for the environment.

Plenty. They are known as pathogenic bacteria. Visit the bacteria museum online,
