Agar definition is - a gelatinous colloidal extract of a red alga (as of the genera Gelidium, Gracilaria, and Eucheuma) used especially in culture media or as a gelling and stabilizing agent in foods.
Agar is commonly used in the laboratory to help feed and grow bacteria and other microorganisms. It acts as a culture that provides nutrients and a place for these items to grow, but since it is...
Uses of Nutrients Agar. 1. It is frequently used for isolation and purification of cultures. 2. It can also be used as a means for producing the bacterial lawns needed for antibiotic sensitivity tests. In actuality, antibiotic sensitivity testing is typically performed on media specially formulated for that purpose. Pictures
Agar is used to gel many food products, such as puddings, desserts, jelly candy, soups, sauces, and more. It is a popular vegetarian alternative to gelatin . Vegetarians and vegans do not use gelatin because it is made from animal bones, skin, and connective tissue.

The agar that we find in science laboratories has been dissolved first in boiling water and then cooled. That is why it looks gelatinous.
A 1.5% solution of agar-agar forms a gel on cooling to about 32º to 45º C that does not melt below 85º C. This hysteresis interval is a novel property of agar-agar that finds many uses in food applications. The gel strength of the agar-agar is influenced by concentration, time, pH, and sugar content.
The use of agar in bacteriology is one of the most important uses and requires strict physical-chemical control as well as the absence of hemolytic substances and what is more important and difficult, the absence of any bacterial inhibitors.
In dentistry, agar is used to make dental impressions. In manufacturing processes, agar is used as an ingredient in emulsions, suspensions, gels, and certain suppositories. How does it work?

In order to do this in the most effective way, it is important to use a growth medium that is as close as possible to the natural environment. Nutrient broth with agar is called nutrient agar. The overall purpose of the agar is to customize the media for the specific bacteria.
Nutrient agar is used as a general purpose medium for the growth of a wide variety of non-fastidious microorganisms. It consists of peptone, beef extract and agar. This relatively simple formulation provides the nutrients necessary for the replication of a large number of non-fastidious microorganisms.
Agar, a gelatin-like substance extracted from red algae, is commonly used to culture microorganisms. Various nutrients are added to agar to enhance the growth of bacteria in either shallow plates or test tubes. When agar media is placed in test tubes it is in liquid form.
