What supports the growth of microorganisms?

depends on what classes of microbe you are reffering to: aerobic (needs oxygen) or anaerobic (oxygen is poison to them). Most all microbes love molasses and high starch items like rice. These substrates offers a wide spectrum of minerals and sugars. The minerals provide "enzyme bridges" for different kinds of microbes to exist "happily" together (even aerobes and anaerobes).

Yeast can grow on all sorts of agar plates.  They don't need fancy cell culture conditions like mammallian cell lines do.\n\nhttp://www.midsci.com/docs/qbio/ChapterPDF/EU_04.pdf#search='media%20for%20yeast%20growth'  those guys sell some yeast growth media.  \n\nA kind I've used before is SAB (per liter: 40g glucose/10g peptone/5g agar).\n\nI would go with agar plates instead of liquid culture because it will be easier to insure uniform exposure.  The yeast should also remain viable for longer on plates than in liquid culture. \n\nThis sounds like a clever idea for an experiment, good luck.

Most of the bacteria that can be cultured represent only a tiny fraction of what's out there. Bacteria exist in practically every niche observable but in general, the best way to cultivate bacteria is to simulate their natural environment. That's why many infectious bacteria are grown on agar (a sugar similar to the ones found in our body) and incubated at 37 degrees celsius (the temperature of the human body)

can do the following:\n\n1. Add microbial agents to antimicrobial agents\n\n2. Add Macrobial Agents\n\n3. Add Antimicro-unial agents

Procedures used to prevent the introduction of fungi, bacteria, viruses, mycoplasma or other microorganisms into cell, tissue and organ cultures. Although these procedures are used to prevent microbial contamination of cultures, they also prevent cross contamination of cell cultures as well. These procedures may or may not exclude the introduction of infectious molecules.

You have to be more specific.  Microorganisms grow in pretty much every condition on Earth, including hot and sulfurous ocean water by volcanic vents, in ice at the poles, in badly-preserved jars (botulism--anaerobic), inside the body, in ponds, in caves, in the dark, in the sunlight...it all depends on the specific type of microorganism.\n\nFor instance, sugar tends to kill bacteria, but mold loves sugar.  So a jar of jelly left in a fridge for a long time (cold, wet, sugary environment for the microorganisms) might not have bacteria, but it could have fuzzy mold on it.  It all depends.  \n\nBut from a food safety standpoint, you want food kept either below 40 degrees fahrenheit, or above 140 degrees, and keep it wrapped up and covered to avoid stuff dropping in it.  In general, microorganisms like: warm (not hot or cold), dark, moist, and somewhat neutral pH.  That'll grow mold, mildew, fungus, and many types of bacteria.  They usually don't like clean surfaces and they tend to die in chlorine bleach.

Microogranisms provide massive amounts of oxygen to the environment. Also, they help to decompose dead organic matter.

There are many reasons microbiologists are needed in the oil and gas industries.  For one, there are bacteria that can live in those substances and use them for consumption.  There are bacteria that live in jet fuel as well.  As long as there is some type of nutrition available for the microorganisms, they will thrive and reproduce.  These microbiologists help by testing samples for microbial growth.  Did you know that certain microbial growth in diesel fuel can produce plant life.  I've worked out in the oilfield and have seen it first hand.  I now have a degree in Biology and am working on a Masters Degree.  \nThese same microbiologists are also working on fuel alternatives using bacteria to produce ethanol through fermentation.  They can get it through citrus fruits to mass produce but it is hard for them to breakdown cellulose so they are trying to engineer a new type of bacteria that will be able to break down the cellulose and create more ethanol.  This is what I am currently doing research on.  Cool huh.

Lysogeny broth (LB), a nutritionally rich medium, is primarily used for the growth of bacteria. It is also known as Luria broth or Luria-Bertani broth.\n\nLB media formulations have been an industry standard for the cultivation of Escherichia coli as far back as the 1950s. These media have been widely used in molecular microbiology applications for the preparation of plasmid DNA and recombinant proteins. It continues to be one of the most common media used for maintaining and cultivating recombinant strains of Escherichia coli.\n\nThere are several common formulations of LB. Although they are different, they generally share a somewhat similar composition of ingredients used to promote growth, including the following:\n\nPeptides and casein peptones \nVitamins (including B vitamins) \nTrace elements (e.g. nitrogen, carbon, sulfur) \nMinerals \nPeptides and peptones are provided by tryptone. Vitamins and certain trace elements are provided by yeast extract. Sodium ions for transport and osmotic balance are provided by sodium chloride. Bacto-tryptone is used to provide essential amino acids to the growing bacteria, while the bacto-yeast extract is used to provide a plethora of organic compounds needed for bacterial growth

the best known good role is the normal flora which is the microbes of the skin, intestine.. that are naturally thier some produce antibiotics that kills pathogenic bacteria and some produce vitamins..some lactobacilli produce lactic acid in the vagina and prevent the growth of fungi like Candida albicans

Yes. They are probably microbes or even smaller nanobacteria. \n\nI have seen the work of Dr. Robert Folk at the University of Texas, who examined the Martian meteorites found in Antarctica and found possible fossil evidence of nanobacteria. Many biologists are not convinced that nanobacteria (which are measured in nanometers) even exist and argue that they are too small to contain the functions of a living cell. The topic remains controversial.   \nHere is a page discussing the biological controversy (there are some geological controversies as well):\nhttp://serc.carleton.edu/microbelife/topics/nanobes/index.html\n\nHere is the NASA page describing the findings:\nhttp://nssdc.gsfc.nasa.gov/planetary/marslife.html

Sucrose actually helps in the growth of Trychophyton rubrum since I have seen abundant growth when i added more of it in the SDB & SDA medium.

The study of microorganisms, which includes viruses, bacteria, certain fungi, and protists (like paramecia and algae).

Tryptic Soy Agar. It's the basic medium (food in a petri dish or test tube) for growing bacteria.

the use of microorganisms, such as bacteria or yeasts, or biological substances, such as enzymes, to perform specific industrial or manufacturing processes. Applications include production of certain drugs, synthetic hormones, and bulk foodstuffs.

It depends on what sort of microorganisms you wish to grow.  If you'd like protists, just go to any local pond, take a sample of the water and you'll have an instant microcosm.  If you're specifically interested in bacteria or fungi- all you really need to do is leave out some moist, fatty nutrient-rich substance (like milk) and soon enough mold spores (mold is a fungus, by the way) in the air will settle and grow, as will bacteria.  (It's important to note that there is no such thing as "spontaneous generation" - These microorganisms will grow from air-borne spores or spores that are already present in the container / within the substance you grow them.  They don't just simply generate from nothing.)
