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 ]
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 ...

Welton Ivan Taylor (November 12, 1919 – November 1, 2012) was an American microbiologist, inventor and civil rights activist.He is known for his work on food-borne pathogens, notably for developing tests for Salmonella and for inventing the XLD (Xylose Lysine Deoxycholate) agar, which can be used to isolate Salmonella and Shigella bacteria.
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens.

HuffPost reviewed logs documenting complaints inside state youth prisons recorded between 2008 and 2012. Those logs show that several of the YSI facilities that received positive “quality assurance” reviews also generated an outsize share of staff arrests, youth injuries and allegations of excessive force.
Xylose-lysine-deoxycholate agar is used for the culture of stool samples and contains two indicators. It is formulated to inhibit Gram-positive bacteria, while the growth of Gram-negative bacilli is encouraged. The colonies of lactose fermenters appear yellow.
