Xylose lysine deoxycholate agar (XLD agar) is a selective growth medium used in the isolation of Salmonella and Shigella species from clinical samples and from food. [ 1 ] [ 2 ] The agar was developed by Welton Taylor in 1965. [ 3 ]
After 24 hours of growth, this image depicts four different agar media culture plates that had been inoculated with Shigella sp., Escherichia sp., and Proteus sp. bacteria, (clockwise: MacConkey, Shigella-Salmonella, Bismuth Sulfite, and Brilliant Green agars).
As there are many bacteria that also look like Salmonella on DCA, it is widely recommended that more selective agars are used for the identification of Salmonella, namely xylose lysine deoxycholate (XLD) agar. This growth medium is heat-sensitive and should be poured and cooled as soon as possible after addition of the deoxycholate, otherwise ...
XLD may refer to: Xylose lysine deoxycholate or XLD agar, a growth medium for bacterial cultures; The XLD connector, a keyed variant of the XLR connector;
The components of SOC medium should not be autoclaved together because at elevated temperature glucose can react with the tryptic peptides (see Maillard reaction), compromising the quality of the preparation. SOB and magnesium and glucose additive solutions can be autoclaved separately and mixed afterwards to the final concentrations.
If you have an inherited intolerance to alcohol, a mutated gene could be the culprit. An at-home DNA test could detect whether you have the mutation, but doctors say there could be some drawbacks.
