Thermo Fisher, PO5104A, PALCAM Medium

Unit Size: Each
Use PALCAM Medium for selective isolation and easy differentiation of L. monocytogenes.
• Selective: The addition of lithium chloride, ceftazidime, polymyxin B and acriflavine hydrochloride make the medium highly selective forListeria monocytogenes.
• Easy to read:L. monocytogenesforms brown/black colonies with a black halo while mannitol positive accompanying flora, such as staphylococci and enterococci, grow as yellow colonies.
• Ready-to-use convenience of prepared media.PALCAM Medium allows easy differential diagnosis of L. monocytogenes by utilising the double indicator system.
• Aesculin and ferrous iron
• Mannitol and phenol redL.monocytogenes hydrolyses aesculin resulting in the formation of a black halo around colonies. L. monocytogenes does not ferment mannitol so can be easily differentiated from contaminants, such as enterococci and staphylococci, which ferment mannitolproducing a change from red to yellow in the pH indicator phenol red.Not all products are available for sale in all territories.
