SKU: PP0322 Category:

Xylose Lysine Deoxycholate (XLD) Agar is used for the isolation and detection of Salmonella and Shigella spp. It differs from other media of this type in that it has less sodium deoxycholate as its selective agent. The indicator system is somewhat complex taking advantage of the fermentation or otherwise of three carbohydrates (lactose, sucrose and xylose) together with lysine decarboxylase and sodium thiosulphate as an indication of the presence or absence of hydrogen sulphide. The addition of novobiocin (20mg/L) improves the inhibition of Proteus spp.
