What is Thioglycolate used for?
Thioglycolate agar is used for the cultivation of aerobic and anaerobic microorganisms in sterility tests and to determine the oxygen requirements of the microorganisms. It is the most frequently used medium in diagnostic bacteriology.
Why tryptone is used in culture media?
Tryptone is an enzymatic digest of casein used as a nitrogen source in culture media. Casein is the main protein of milk, and a rich source of amino-acid nitrogen. Tryptone is rich in tryptophane, making it valuable for use in detecting indole production.
What test is tryptone broth used for?
the indole test
Tryptone broth is frequently used for the indole test, important for identifying enteric bacteria.
