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. It contains cystine and lactose and is electrolyte -deficient; the latter trait prevents the swarming of Proteus species.
CLED agar – cysteine, lactose, electrolyte-deficient agar is used to isolate and differentiate urinary tract bacteria, since it inhibits Proteus species swarming and can distinguish between lactose fermenters and nonfermenters. Granada medium is used to isolate and differentiate group B Streptococcus, Streptococcus agalactiae from clinical ...
Label the base of the plate. Then, visualize the plate in four quadrants: top left (I), top right (II), bottom right (III), bottom left (IV). Streak the mixed culture back and forth in the first quadrant (top left) of the agar plate. Do not cut the agar, simply scrape the top. Flame the loop to rid of culture residue.

Schädler agar is composed of several key ingredients that provide the necessary nutrients and environment for anaerobic bacterial growth: [2] Peptones: serve as a source of nitrogen and amino acids. Yeast extract: provides vitamins, particularly B vitamins, and other growth factors. Dextrose: a source of carbon and energy.
MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.
LB medium bottle and LB agar plate Plate medium agar LB. Lysogeny broth (LB) is a nutritionally rich medium primarily used for the growth of bacteria. Its creator, Giuseppe Bertani, intended LB to stand for lysogeny broth, [1] but LB has also come to colloquially mean Luria broth, Lennox broth, life broth or Luria–Bertani medium. [2]
Nutrient agar is a general-purpose solid medium supporting growth of a wide range of non-fastidious organisms. It typically contains ( mass/volume ): [ 1 ] 0.5% peptone – this provides organic nitrogen
