MCTA (TSA+Lec+Tw80)

APPLICATION

Tryptic Soy Agar (TSA) is a non selective isolation medium used for the growth of bacteria which do not have specific nutritional requirements and for the preparation of reference strains with the aim of growth promotion tests of culture media. This medium complies with the recommendations of the harmonized method in the United States Pharmacopoeia (USP) and European Pharmacopoeia (EP).

PRINCIPLE AND INTERPRETATION

Tryptone Soy Agar plates are provided for environmental monitoring and in particular for air monitoring inside environmentally-controlled areas.

The inactivation of residues of disinfectants is critical for the detection of viable and cultivable microorganisms in pharmaceutical production environments. For this purpose this mediumis enriched with lecithin which neutralizes quaternary ammonium compounds and Tween 80 which is effective against phenolic compounds and mercurial derivates.
