Biosynth Chromogenic Medium (BCM) for Listeria monocytogenes
(Biosynth Chromogenic Medium (BCM) for Listeria monocytogenes is available commercially)
The proprietary BCM Listeria monocytogenes Plating Medium contains a substrate for phosphotidylinositol-specific phospholipase C (PlcA) enzymes that differentiates L. monocytogenes and L. ivanovii from other Listeria species. It can be obtained commercially as a dehydrated basal medium plus supplements. Differential activity for all Listeria species is due to the addition of a chromogenic substrate.
