Popis

General description

Tryptone Soya Agar with Polysorbate 80 and Lecithin is used for determining the efficiency of sanitization of containers, equipment surfaces, water miscible cosmetics, etc. Tryptone and soya peptone provide nitrogenous and other nutrients required for the replication of microbes. Lecithin and Polysorbate 80 neutralize many residual disinfectants. Polysorbate 80 inactivate phenols, hexachlorophene and formalin, while lecithin neutralizes quaternary ammonium compounds.

Application

Tryptone Soya Agar with Polysorbate 80 and Lecithin is used to identify and quantify viable microbial contaminants present on surfaces of sanitary importance

Preparation Note

Suspend 45.7 grams in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 12 to 15 lbs pressure (118°C - 121°C) for 15 minutes.
