uses of nutrint agar?

Answer 1

Nutrient agar is a general purpose medium used for the examination of water and dairy products. It is also used for the cultivation of the majority of the less fastidious microorganisms.

Answer 2

Nutrient agar is used throughout the world as a medium for the growth of bacteria and fungi, but not viruses (however, a particular type of viruses - bacteriophages - are often grown in bacteria that are growing on agar). Though less than 1% of all existing bacteria can be grown successfully, the basic agar formula can be used to grow most of the microbes whose needs are known. More specific nutrient agars are available, because microbes can be picky. For example, blood agar, which is generally combined with horse blood, can be used to detect the presence of haemorrhagic micro-organisms such as E.coli O:157 H:7. The bacteria digest the blood, turning the plate clear
Selective media is agar specially treated to apply a selective pressure to organisms growing on it -- for example, to select for salt-tolerant, gram-positive, or gram-negative bacteria. To select for only gram negative organisms you would use MacConkey agar, which would also in turn tell you if the gram negative organism is a lactose fermenter or not indicated by red colonies instead of translucent (non- lactose fermenter).

Differential media includes an indicator that causes visible, easily detectable changes in the appearance of the agar gel or bacterial colonies in a specific group of bacteria. For example, EMB (Eosin Methylene Blue) agar causes E. coli colonies to have a metallic green sheen, and MSA (Mannitol Salt Agar) turns yellow in the presence of mannitol fermenting bacteria

Answer 3

Agar is a gelatinous substance chiefly used as a culture medium for microbiological work. Other uses are as a laxative, a vegetarian gelatin substitute, a thickener for soups, in jellies, ice cream and Japanese desserts such as anmitsu, as a clarifying agent in brewing, and for paper sizing fabrics. It is an unbranched polysaccharide obtained from the cell walls of some species of red algae or seaweed. The word agar comes from the Malay word agar-agar (meaning jelly). It is also known as kanten or agal-agal (Ceylon agar). Chemically, agar is a polymer made up of subunits of the sugar galactose. Agar polysaccharides serve as the primary structural support for the algae's cell walls

Answer 4

Nutrient Agar is used to culture micro organisms for testing and experimentation. Some of these micro organisms are used to check diseases and such.

Answer 5

netrient agar media is general media,
which helps in performing bacterial culture,
especially to cultivate gram positive bacteria,
some of pathogenic and some of non pathogenic,
gram negative bactreia will not grow on this media

we can use this media for
=>> urine culture
>> and to grow e, coli
