L. mono Confirmatory Agar Base, 2.5KG

L. mono Confirmatory agar base is recommended for the selective and differential isolation of Listeria monocytogenes from clinical and food specimens. Differentiation of L.monocytogenes from other Listeria species is based on phosphatidylinositol-specific phospholipase C (PIPLC) activity and fermentation of a-Methyl D-mannoside. Phospholipase C enzyme activity results in the formation of an opaque halo around the colonies. Listeria monocytogenes, Listeria ivanovii exhibit positive PIPLC activity, Listeria ivanovii appears as light purple colony while Listeria monocytogenes produce yellow colored colony. Application: For Laboratory Chemicals, Analytical Purpose, Biochemical Analysis Appearance: Beige to purple homogeneous free flowing powder Gelling: Firm, comparable with 1.2% Agar gel Color and Clarity of prepared medium: Purple colored, opalescent gel forms in Petri plates Reaction: Reaction of 7.7% w/v aqueous solution at 25°C. pH : 7.2±0.2 Cultural Response: Cultural characteristics observed with added supplements, L.mono Selective supplementI (FD212), L.mono Selectivec Supplement II (FD213) and L.mono Enrichment Supplement II (FD227), after an incubation at 35-37°C for 24-48 hours
