Tryptone Glucose Extract (TGE) Agar is used for the cultivation and enumeration of microorganisms in dairy and bottled water products. Tryptone Glucose Extract (TGE) Agar is not intended for use in the diagnosis of disease or other conditions in humans.

In the 1930’s, Bower and Hucker developed a medium for detecting bacteria in milk and other dairy products. Prickett used a glucose agar containing tryptone to study thermophilic bacteria in milk. This medium is known as Yeast Dextrose Agar. In 1948, the American Public Health Association (APHA) adopted Tryptone Glucose Extract Agar for use in testing milk and dairy products. Currently, APHA specifies Tryptone Glucose Extract Agar for the heterotrophic plate count procedure in testing bottled water. Tryptone Glucose Extract Agar is also known as Yeast Dextrose Agar.
