Product Description
Xylose Lysine Deoxycholate Agar (XLD agar) is a widely used selective and differential medium in microbiology labs. Designed to isolate and identify Salmonella and Shigella species from clinical, food, and environmental samples, these pre-poured plates simplify workflow while ensuring reliable results.
The medium contains xylose, lysine, and deoxycholate, which inhibit gram-positive bacteria while allowing gram-negative enteric pathogens to grow. The inclusion of phenol red as a pH indicator helps differentiate lactose-fermenting and non-lactose-fermenting organisms, making it easier to identify target pathogens.
Each plate is manufactured under strict quality control to ensure consistency and performance. Whether you’re a student, researcher, or lab technician, these XLD agar plates provide a convenient solution for routine microbiological testing.

The plates are ready-to-use, eliminating the need for media preparation and reducing the risk of contamination. Their long shelf life and stable formulation make them ideal for both educational and professional settings.
For best results, store the plates in a cool, dry place away from direct sunlight. Always follow standard microbiological practices when handling and disposing of used plates.
FAQs
What is Xylose Lysine Deoxycholate Agar used for?
XLD agar is primarily used to isolate and differentiate Salmonella and Shigella species from clinical, food, and environmental samples. It is a selective medium that inhibits gram-positive bacteria while allowing gram-negative enteric pathogens to grow.
How do I interpret results on XLD agar plates?
Salmonella and Shigella colonies typically appear as red or colorless with black centers due to H2S production. Lactose-fermenting organisms like E. coli produce yellow colonies, while non-lactose fermenters remain red or colorless.
Can I use XLD agar for other bacteria besides Salmonella and Shigella?
While XLD agar is
