Bacteriological Agar is the solidifying agent. Sodium desoxycholate is the selective agent inhibiting Gram-positive microorganisms. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Yeast extract is the source of vitamins, particularly of the B-group essential for bacterial growth. The bacteria that decarboxylate the L-Lysine to cadaverine are identified by the presence of a purple-red color around the colonies due to the elevation of the pH. Polystyrene Petri plates feature raised rings for stacking ability and prevents sliding. For selective isolation of pathogenic enteric gram negative bacteria. Once the salmonellae consume the xylose, lysine is attacked via the enzyme, lysine decarboxylase, with a reversion to an alkaline pH which is similar to the Shigella reaction. XLD ( Xylose Lysine Deoxycholate) Agar, Hardy Diagnostics. Lysine allows the Salmonella group to be differentiated from the non-pathogens since, without it, salmonellae would quickly ferment the xylose and be indistinguishable from non-pathogenic species. Sodium thiosulfate serves as a reactive substance, with Ferric ammonium citrate as an indicator of the formation of hydrogen sulfide under alkaline conditions. The reactions that take place are the degradation of the three fermentable carbohydrates: xylose, lactose and sucrose, with the production of acid, manifested in the color change from red to yellow. It has been shown to be more effective than other enteric differential media. XLD Agar (Xylose Lysine Desoxycholate Agar) was developed principally for isolating and differentiating Gram-negative enteric bacilli, particularly Shigella and Salmonella.
