S2 Media 15x100mm Xylose Lysine Deoxycholate (XLD) Agar, 10/pack
Supplier: S2 Media 5020
Xylose Lysine Deoxycholate (XLD) Agar is a selective and differential medium used for the isolation of enteric pathogens. Salmonella species are able to ferment xylose to produce acid, but not lactose or sucrose. When the xylose is exhausted Salmonella will decarboxylate lysine shifting the pH back to neutral. At near neutral pH, Salmonella can reduce sodium thiosulfate producing hydrogen sulfide which creates a complex with ferric ammonium citrate to produce black or black centered colonies. Other organisms are able to decarboxylate lysine, but acid production from the fermentation of lactose and sucrose keeps the pH too acidic for H2S production. • Product meets AOAC, BAM, CLSI, ISO, NF, SM-Dairy, SMWW, and Harmonized USP/EP/JP reference methods and performance criteria.• XLD should be used by trained professionals within a laboratory setting. • For in vitro diagnostic (IVD) use.• Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
