PALCAM Selective Supplement Himedia

About PALCAM Selective Supplement Himedia

PALCAM Selective Supplement is a microbiological laboratory reagent designed for preparing PALCAM Agar, a selective and differential culture medium used for the isolation and presumptive identification of Listeria species, particularly Listeria monocytogenes, from food and environmental samples. The supplement contains selective antimicrobial agents that help inhibit competing microorganisms and improve the recovery of target organisms when used with the recommended basal medium. PALCAM Agar differentiates organisms through characteristic reactions involving esculin hydrolysis and mannitol fermentation, supported by appropriate indicators in the basal medium. The supplement is used in food microbiology laboratories, quality-control facilities, public health laboratories, and research settings. It is supplied in a concentrated, prepared supplement format and must be reconstituted or added according to the manufacturer's instructions. The exact antimicrobial composition, quantity per vial, and recommended preparation procedure depend on the specific HiMedia catalogue product. Use appropriate aseptic technique and follow the product insert for storage, handling, and disposal.
