Yeast Extract Agar

	Yeast Extract Agar Yeast extract agar is a growth medium containing yeast extract. It may refer to: * The nonselective yeast extract agar of Windle Taylor * YM (selective medium), for yeasts and molds * Buffered charcoal yeast extract agar Buffered charcoal yeast extract (BCYE) agar is a selective growth medium used to culture or grow certain types of bacteria, particularly the Gram-negative species ''Legionella pneumophila''.

picture info	Growth Medium A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation or small plants like the moss ''Physcomitrella patens''. Different types of media are used for growing different types of cells. The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and those used for microbiological culture, which are used for growing microorganisms such as bacteria or fungi. The most common growth media for microorganisms are nutrient broths and agar plates; specialized media are sometimes required for microorganism and cell culture growth. Some organisms, termed fastidious organisms, require specialized environments due to complex nutritional requirements. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells. Types The most common growth media ...

picture info	Yeast Extract Yeast extracts consist of the cell contents of yeast without the cell walls; they are used as food additives or flavorings, or as nutrients for bacterial culture media. They are often used to create savory flavors and umami taste sensations, and can be found in a large variety of packaged food, including frozen meals, crackers, snack foods, gravy, stock and more. They are rich in B vitamins (but not B12). Yeast extracts and fermented foods contain glutamic acid (free glutamates), an amino acid which adds an umami flavor. Glutamic acid is found in meat, cheese, fungi (mushrooms and yeast), and vegetables—such as broccoli, and tomatoes. The heat-autolytic process to make yeast extract of the autolysate type was invented in the 19th century by Justus von Liebig. Yeast cells are heated until they rupture, then the cells' own digestive enzymes break their proteins down into simpler compounds (amino acids and peptides), a process called autolysis. The insoluble cell walls are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	YM (selective Medium) YM Agar and Broth, is a selective growth medium with low pH useful for cultivating yeasts, molds, or other acid-tolerant or acidophilic organisms, while deterring growth of most bacteria and other acid intolerant organisms. It is malt extract medium modified by the addition of yeast extract and peptone. The 'YM' of the name stands either for 'Yeast and Mold', or 'Yeast extract-Malt extract' depending on the source. Variations include YMG agar/broth, which contains yeast, malt, and glucose Glucose is a simple sugar with the molecular formula . Glucose is overall the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using ....

	Buffered Charcoal Yeast Extract Agar Buffered charcoal yeast extract (BCYE) agar is a selective growth medium used to culture or grow certain types of bacteria, particularly the Gram-negative species '' Legionella pneumophila''. It has also been used for the laboratory diagnosis of ''Acanthamoeba'' keratitis, ''Francisella'' and '' Nocardia''. This culture is to be differentiated from regular ''yeast extract agar Yeast extract agar is a growth medium containing yeast extract.
