Soyabean Casein Digest Agar with 0.5% Polysorbate 80 and 0.05% Soya Lecithin Plate is used for cultivation of a wide variety of microorganisms and for environmental monitoring in sterile area.
In 1948, Weber and Black reported lecithin, added to an agar medium in sufficient concentration, would effectively neutralize quaternary ammonium compound. In further testing, Brummer combined lecithin and polysorbate 80 in an agar medium and reported it adequately neutralized disinfectants. Soyabean Casein Digest Agar Plate with 0.5% Polysorbate 80 and 0.05% Soya Lecithin Plate is also used in environmental air sampling procedures.
