MAST X.L.D. Agar – 500g

MAST X.L.D. Agar is a selective and differential culture medium used for the isolation of enteric pathogens, particularly Salmonella and Shigella species, from clinical and food samples. X.L.D. means Xylose Lysine Deoxycholate. The formulation differentiates organisms through xylose, lactose and sucrose fermentation, lysine decarboxylation and hydrogen sulphide production. Sodium deoxycholate provides selectivity by suppressing many unwanted Gram-positive organisms. Key Features - Selective medium for isolation of Salmonella and Shigella - Suitable for clinical and food microbiology - Differentiates bacteria according to carbohydrate fermentation - Detects hydrogen sulphide production - Contains xylose, lactose and sucrose - Contains L-lysine for differentiation of Salmonella - Sodium deoxycholate provides selective inhibition - Phenol red serves as the pH indicator - Supplied as dehydrated powder - Approximate final pH: 7.3 - Product code: DM230D - Pack size: 500g Specification Details Product Name X.L.D.
