Autoclaving affects the pH of the dissolved medium, hence it is preferable to check the pH after autoclaving. pH should be checked at a temperature between 20-25°C. Adjustments can be made with HCl/NaOH if needed, while stirring.

General description
Tryptic Soy Agar is a general-purpose culture medium for the isolation and cultivation of fastidious and non-fastidious microorganisms or the maintenance of stock culture. It is a complex medium for the cultivation and isolation of a wide range of bacteria, yeasts, and molds. The formulation of the TSA medium contains a combination of casein and soy peptones supplying organic nitrogen, particularly amino acids, and longer-chained peptides. Sodium chloride maintains the osmotic equilibrium, and the natural sugars from soy peptone are the energy source.
Application
Tryptic Soy Agar is used for the pre-cultivation and enumeration (E. coli) by membrane filtration technique. It is suitable for the cultivation of both aerobic and anaerobic bacteria. Since it does not contain the X and V factors, it is suitable for the identification of Haemophilus sp. by adding X (Hemin) and V (DPN=NAD) factors strips.
