Yogurt and cheese - Lactobacillus is the bacteria that is used for these.\n\nBread, wine/beer - Fungi in the form of yeast are used for these.\n\nYeast feeds off the sugars that are around and generate carbon dioxide which creates the bubbles that helps bread rise. It ferments the sugars to help make wine and beer.\n\nBacteria is helped used to process certain foods to alter the way they are - like from milk to yogurt or cheese. The presence of this bacteria helps prevent other bacteria from forming, thus helping to preserve milk by making cheese for example.

Chocolates contain a lot of sugar.  Bacteria that live on our teeth can feed on this sugar, and as they do they produce acidic compounds that can damage our teeth.\n\nBrushing your teeth regularly helps remove some of these bacteria, as well as the excess nutrients from the food we eat (that the bacteria can feed on).

Yeast is neither a bacteria OR a mold.  It is a fungus! Molds are a type of fungus too, and yeasts are closely related.  The green stuff and other fluffy stuff that grows on bread at times is not yeast.\n\nMold reproduces with spores, and the spores are essentially everywhere, they just need the right environment to grow in.  They need some dampness, but can grow in places that have relatively little liquid water, unlike most bacteria.  They seem to do well in and on media that are osmotically unfavorable for keeping water inside of a membrane, like cheeses, jellys and bread. Seems like when there is an abundance of water, other organisms tend to outgrow the mold, but go someplace hostile, like the surface of really sugary jam or jelly, so sugary that ordinary bacteria have all their water leach out of them if they try to grow in it, and mold pretty much rules. Wikipedia probably has more information.

Simple...ALL antibiotics that we use to treat bacterial infections and ifestations come from fungi themselves. It's just natural that fungi will have a resistance to these antibiotics that they release.\n\nA rather different approach must be used to stop fungal infection and proliferation not because they have a "tougher" cell wall or because they are eukaryotes--these things are more trivial than what people think. The difficulty in treating them is how to disintegrate their nucleic acid property (DNA) using a particular chemical without compromising the infected individual (i.e. you cannot just use acid to treat fungus in your skin or else you'll damage your skin also).

Fungi live wherever there is a food source available. Ask yourself some questions: does the soil have abundant vegetation growing in it? is the soil in a moist environment? Most fungi feed on and decompose dead material and live in moist, humid environments. since soil is made of mostly dead plant material(with some dead animal material and some nonorganice material like sands and gravel) you will most likely have fungi living in the soil, decomposing and breaking down the nutrients from the dead plant material so living plants can use those nutrients.you can sometimes see  reproductive structures of fungus sticking out above the soil surface (like mushrooms and mold patches), but the body of the fungi (called hyphae) is usually found weaved into the soil below and throughout the surface. some fungi even benefit by living with plant roots, which is another place to find them. to be absolutely sure soil has fungus in it, you'd probably have to do some tests to detect chemical changes in the soil caused by fungi. hope that answers your question :)

fungi and bacteria enter the body a number of ways. fungal spores may just settle on the body surface, meet suitable conditions and then grow. their spores could also enter us through improperly prepared food that houses them. bacteria go in much the same way, even though certain locomotive facilities afford them the ability to actively infiltrate us through cuts on our bodies. that's why its bad to walk across or swim in unclean water, especially when the skin is breached. water we drink is a major entry agent as well.

Grass grows.  Grazing animals (herbivores) eat grass and convert it to flesh.  Meat eating animals (carnivores) catch and eat herbivores.  Carnivores die.  Bacteria, fungi and other micro-organisms cause decay.  The decay products help fertilse the grass so it can grow, and the process repeats.\n\nIt is a little more complicated than that, but the  basics are as set out above.

it's totally depends on the type of the bacteria!\n1)sterilization:fungi is so sentitive to this condition.but if the bacteria is the kind that produce endospore then this method is not useful\n2)pasteurization:kills all the bacterias except the one couses Query\n3)filterization:useful for bacterias except Mycoplasma\n4)Rays like UV X and Gamma\n5)chemical Gases which are mutagenes like rays\n6)chemical liquids

the above answer is wrong.  neither one has anything to do with making your own food.  in fact I wonder if you have your terms backwards.  prokaryotes are bacteria, eukaryotes are everything else.

To gain a better understanding of microorganisms (and their biological processes) and the part that they play in the world.\n\nMost often, you hear about these terms in the study of pathogens (diseases) that affect humans and animals. However, some parasites are useful and have formed a symbiotic relationship with their host organsism.\n\nFor example, the infamous E. coli bacteria can cause illness if it gets into the wrong parts of your body, but are quite helpful if they stay put. \n\nMicrobiolgy also helps understand how the life processes work done at the cellular level. This helps us formulate drugs and treatments for different ailments, from mineral deficiencies to cancers.\n\n~X~

There are tons of bacteria in our bodies that are there to help our body work.  E. coli in the digestive tract helps break down food.

Although often inconspicuous, fungi occur in every environment on Earth and play very important roles in most ecosystems. Along with bacteria, fungi are the major decomposers in most terrestrial (and some aquatic) ecosystems, and therefore play a critical role in biogeochemical cycles and in many food webs.\n\nMany fungi are important as partners in symbiotic relationships with other organisms, as mutualists, parasites, or commensalists, as well as in symbiotic relationships that do not fall neatly into any of these categories. One of the most critically important of these relationships are various types of mycorrhiza, which is a kind of mutualistic relationship between fungi and plants, in which the plant's roots are closely associated with fungal hyphae and other structures. The plant donates to the fungus sugars and other carbohydrates that it manufactures from photosynthesis, while the fungus donates water and mineral nutrients that the hyphal network is able to find much more efficiently than the plant roots alone can, particularly phosphorus. The fungi also protect against diseases and pathogens and provide other benefits to the plant. Recently, plants have been found to use mycorrhizas to deliver carbohydrates and other nutrients to other plants in the same community and in some cases can make plant species that would normally exclude each other able to coexist in the same plant community. Such mycorrhizal communities are called "common mycorrhizal networks". Over 90% of the plant species on Earth are dependent on mycorrhizae of one type or another in order to survive, and it is hypothesized that the presence of terrestrial fungi may have been necessary in order for the first plants to colonize land.\n\n\n\nIn soil, microorganisms which reside in the rhizosphere (a zone that includes the root surface and the soil that adheres to the root after gentle shaking) help in the transformation of molecular dinitrogen gas as their source of nitrogen, converting it to nitrogenous compounds in a process known as nitrogen fixation. This serves to provide an easily absorbable form of nitrogen for many plants, which cannot fix nitrogen themselves. Many other bacteria are found as symbionts in humans and other organisms. For example, the presence of the gut flora in the large intestine can help prevent the growth of potentially harmful microbes.\n\nThe ability of bacteria to degrade a variety of organic compounds is remarkable. Highly specialized groups of microorganisms play important roles in the mineralization of specific classes of organic compounds. For example, the decomposition of cellulose, which is one of the most abundant constituents of plant tissues, is mainly brought about by aerobic bacteria that belong to the genus Cytophaga. This ability has also been utilized by humans in industry, waste processing, and bioremediation. Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills. Some beaches in Prince William Sound were fertilized in an attempt to facilitate the growth of such bacteria after the infamous 1989 Exxon Valdez oil spill. These efforts were effective on beaches that were not too thickly covered in oil.\n\nBacteria, often in combination with yeasts and molds, are used in the preparation of fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, and yogurt. Using biotechnology techniques, bacteria can be bioengineered for the production of therapeutic drugs, such as insulin, or for the bioremediation of toxic wastes.\n\n"Friendly bacteria" is a term used to refer to those bacteria that offer some benefit to human hosts, such as Lactobacillus species, which convert milk protein to lactic acid in the gut. The presence of such bacterial colonies also inhibits the growth of potentially pathogenic bacteria (usually through competitive exclusion). Other bacteria that are helpful inside the body are many strains of E. coli, which ar

A mushroom belongs to the Fungi kingdom. All fungi are heterotroph meaning they cannot produce their own food, they absorb their nutrients from the environment. Mushrooms get their nutrients from either the soil or the trees they are growing on ( bracket fungi).Most fungi are saprobic meaning they decompose dead plants and animals and absorb the nutrients. Some are parasitic, they obtain their nutrients from living organisms.

Mycotoxins are toxic metabolites produced by different genera of fungi (Aspergillus, Fusarium, Penicillium, Claviceps, etc.) that can contaminate a wide range of foods and feeds. These fungi are ubiquitous and wide-spread at all levels of the food chain. They are present in food produced at all latitudes save the polar regions.

Bacteria are prokaryotic organisms. They are mostly unicellular, and they have no nucleus and other cell structures.\n\nProtists and Fungi, on the other hand, are eukaryotes, which are unicellular or multicellular organisms that have a nucleus and complex structures like mitochondria and chloroplasts.\n\nfor more details, go to an encyclopedia website like http://www.wikipedia.org

bacteria rots milk until it becomes YOGHURT and it can rot further until CHEESE is made!\n\nAlso don't forget VACCINATIONS... these actually contain a small amount of the disease in question so that your body can fight it (without becoming ill).  If ever you get infected for real your body now knows what to do and fights it off!\n\nYEAST is used to make bread and the brewing of beer\n\nhope this helps! :-)

Most plants, including more that 90% of all trees, have special fungi associated with their roots. These fungi help plants absorb nutrients and water. These fungi form a symbiotic association with the roots of nearly all plants to help them grow. Sometimes these microbes become macrobes, large organisms, that you can see as mushrooms.
