BD Difco™ Dehydrated Culture Media: Letheen Broth (AOAC)

Description

For determining the phenol coefficient of cationic surface-active materials

Applications:  For evaluation, maintenance, selective enrichment, differentiation, isolation, cultivation, detection, propagation of bacteria.

Letheen Broth contains beef extract and peptone which provide the carbon and nitrogen sources required for growth of a wide variety of organisms. Lecithin and polysorbate 80 are added to neutralize surface disinfectants. Lecithin is added to neutralize quaternary ammonium compounds and polysorbate 80 is incorporated to neutralize phenols, hexachlorophene, formalin and, with lecithin, ethanol. We do not use it for phenol coefficient determination, but rather for the neutralization of the most commonly encountered antimicrobials in antimicrobial testing of textile products.
