R2A-Agar, granulated, for microbiology, Storage temp. +15 to +25 °C
Nutritionally reduced medium. Incubation of water samples on R2A Agar often leads to higher colony numbers of micro organisms than found for rich media, particularly when incubation is performed at lower temperatures.
The medium was originally developed by Reasoner and Geldreich to determine the total germ number in drinking water (Reasoner and Geldreich, 1985, Appl. Environ. Microbiol. 49:1).

Questions about R2A-Agar, granulated, for microbiology, 500 g, plastic
What is this article?
R2A-Agar, granulated, for microbiology, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Microbiologische media.
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.
