Description
This medium is recommended for use in the cultivation, storage, maintenance and transport of pure cultures of microorganisms (not intended for use in the diagnosis of disease or other conditions in humans). It can be incubated at differing temperatures depending on the target organisms. In environmental monitoring applications, it is common for plates to be incubated at 30-35°C for bacterial colonies and 20-25°C for mould and fungi.
Trypticase soy agar is prepared with casein and soy peptones: the combination of casein and soy peptones makes the medium nutritious by providing organic nitrogen in the form of amino acids and polypeptides. Sodium chloride maintains osmotic balance. Agar is the solidifying agent.
Formula may be adjusted and/or supplemented as required to meet performance specifications.
SA medium is used for a multitude of purposes :
The main application for TSA is in environmental monitoring within pharmaceutical cleanrooms and sterile facilities. It is commonly gamma-irradiated for increased sterility assurance and can be supplemented with neutralisers for disinfectants or enzymes.
It is useful for testing water, cosmetics, industrial products, food and beverages.
Trypticase Soy Agar can also be used as a medium to maintain or subculture reference strains, eg Enterobacteriaceae and Staphylococci.
Very professional understanding of our requirement needs, a pleasure to work with them all. Flexible on time, dates is a key performance that we like to do business with. The service was to the high standard that we required.
