Cystine promotes the formation of cystine-dependent dwarf colonies. Omitting sodium chloride inhibits the Proteus swarming and supports the growth of a great majority of bacteria causing urinary tract infections and is used to differentiate and identify them. It is electrolyte deficient to prevent the swarming of Proteus species. Streptococci and other organisms requiring blood or serum for growth may only be insufficiently recovered on this medium or may need extended incubation. CLED agar (cystine–lactose–electrolyte-deficient agar or medium) is a valuable non-inhibitory growth medium used in the isolation and differentiation of urinary microbes. Therefore, the specimen should also be cultivated onto a blood agar plate if such organisms are expected. Bacillus cereus agar (PEMBA) is used for the selective isolation and enumeration of Bacillus cereus in food samples.

CLED Agar also lacks sodium chloride, which helps to prevent the swarming of Proteus spp. Various cultural responses shown by different microorganisms on CLED Agar at the appropriate atmosphere and temperature after 18 – 24 hours incubation are as follows : Although CLED agar is suitable for the isolation and counting of many aerobically growing microorganisms, such as Enterobacteriaceae, Pseudomonas and other non-fermenting Gram negative rods, enterococci, staphylococci, Candida species, and many others from urine specimens, some common limitations are: why the color turns blue in case of (salmonella spp.)? It is used for the isolation, cultivation and differentiation of gram-negative enteric microorganisms isolated from both clinical and non-clinical specimens such as from feces, urine, and suspected food items (fresh and canned foods). CRITERION™ CLED Agar contains enzymatic digest of casein, enzymatic digest of gelatin, and beef extract, which provide nitrogen, vitamins, and carbon to support microbial growth.
