Neutralizing efficiency of lecithin and polysorbate 80 in ICR contact plates and swabs for surface monitoring

18 Feb 2020

Sample monitoring requires non-selective culture media that should be supplemented with appropriate neutralizers to overcome or minimize antimicrobial activity. To check the suitability of typical mixtures of neutralizers such as LT (lecithin and polysorbate 80), this scientific poster compares several commercially available disinfectants for worst case neutralization efficiency tests.

m-FC Agar

Merck

Membrane Filter Fecal Coliform Agar. Typical Composition (g/L): Proteose peptone 5.0; bile salts 1.5; tryptose 10.0; lactose 12.5; yeast extract 3.0; methyl-blue (formerly aniline blue) 0.1; sodium chloride 5.0; agar-agar 15.0.Application: For the detection of fecal coliforms in water using the membrane filter technique.
