General description

Casein-peptone lecithin polysorbate broth (base) is a granulated medium recommended for general microbiological analysis. The granules ensure rapid and uniform dissolution in water, prevent clumping of the medium, and inhalation of the airborne powder. Casein enzymic hydrolysate provides the nitrogen, vitamins, amino acids, and carbon in the broth base. Casein peptone in the medium present optimal conditions for the spore germination and regeneration of the damaged microorganisms. Lecithin and polysorbate 20 inactivate many antimicrobial compounds.

Application

Casein-peptone lecithin polysorbate broth (base) is recommended for diluting samples of pharmaceutical, cosmetic, and other raw materials or final products for determining the total microbial counts.
