Listeria Identification Broth Base (PALCAM), Granulated

Listeria Identification Broth Base (PALCAM), Granulated is recommended for selective enrichment and identification of Listeria species. Listeria Identification Broth also known as Polymyxin-Acriflavin-Lithium chloride-Ceftazidime-Aesculin-Mannitol (PALCAM) Broth is prepared as described by van Netten et al for selective enrichment of Listeria species. Peptone and yeast extract provide nitrogen and carbon compounds, long chain amino acids and other growth nutrients. High amount of lithium chloride and added selective supplement (FD061) containing polymyxin B, acriflavin hydrochloride and ceftazidime inhibit accompanying microflora and allow the growth of Listeria species.
