Description
XLD agar is a selective and differential culture medium for the isolation and differentiation of gram-negative microorganisms, with particular emphasis on Shigella. The 500 g pack provides a practical quantity for preparing plates used in clinical, food, and research microbiology. After reconstitution according to laboratory protocols, the medium supports selective growth conditions that favour target gram-negative organisms and enable differential colony reading as part of standard identification workflows. It is suited to stool diagnostics, enteric pathogen screening, and related plating procedures where reliable recovery of Shigella and other gram-negative bacteria is required. Offered by manufacturer Dinkelberg, this agar integrates into established media-preparation routines and quality-controlled culture work. The dehydrated format allows flexible batch sizes and straightforward stock management for laboratories that run regular enteric panels. XLD agar remains a recognised choice whenever selective isolation and differentiation of gram-negative microorganisms form part of the analytical programme, and the 500 g unit supports ongoing plate preparation without frequent reordering.
This article belongs on Dehydrated culture media (agar & broth bases), in Culture media & microbiology. See also Petri dishes.

Questions about XLD Agar, PH EUR - USP, 500 g
What is this article?
XLD Agar, PH EUR - USP, 500 g is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Microbiologie.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
