Used as a growth medium in microbiology laboratories to cultivate a wide range of microorganisms, especially fungi and bacteria that require complex nutrient sources. The addition of lecithin helps neutralize inhibitory substances like quaternary ammonium compounds and phenolics, making it suitable for use in microbial recovery from disinfectants and antiseptic products. Tween 80 acts as a surfactant, aiding in the dispersion of hydrophobic substances and promoting even microbial growth. Commonly employed in pharmaceutical, cosmetic, and environmental testing to assess microbial contamination and validate sterilization processes. Its formulation supports the growth of both fastidious and non-fastidious organisms, enhancing its utility in quality control and research settings.
