Urine specimens are inoculated on CLED (cysteine lactose electrolyte deficient) agar because this medium supports the growth of most urinary pathogens while inhibiting the growth of normal urinary flora. It allows for the differentiation of different bacterial species based on colony characteristics and lactose fermentation. CLED agar is also able to identify the presence of UTI-causing organisms such as E. coli, Proteus, and Enterococcus.
Yes, enterococci can grow on CLED (Cystine Lactose Electrolyte Deficient) medium. CLED is designed to support the growth of a wide variety of urinary tract pathogens, including enterococci, while inhibiting the growth of certain contaminants. It allows for the differentiation of lactose fermenters from non-fermenters, which can help in identifying enterococci in clinical samples.
Approximately 2 teaspoons of agar agar powder is equivalent to 7 grams.
red algae Agar agar is a malay term meaning red algae. This algae which agar is extracted lives in the ocean around Malaysia
Yes, some marine bacteria and fungi have been identified to possess the capability to degrade agar agar. These microorganisms secrete enzymes such as agarases that breakdown agar into simpler sugars, which they can then use as a source of energy.

Depends on specimens you are inoculating - given CLED was mentioned I would assume urines. Standard set of PIM for a urine is HBA, MAC and CLED (although some labs omit the CLED). Most commonly encountered organisms in a UTI are enterobacteriaceae, especially E. coli; and other gram negative rods such as Pseudomonas. Can encounter Staphylococci and some other gram positive organisms - especially in hospital settings. Personally, in this situation I would use a CNA, Choc and MAC for urines - CNA grows the staphylococci (and streptococci and enterococci); Choc provides a non-selective media and MAC grows the gram negative rods that are most frequently isolated. Also, if nothing WAS isolated possibly release results with a comment about the accuracy of the results given the inavailbility of blood agar. Cled is useful for swarming proteus, to isolate them - I would attempt to isoalte and ID proteus without a CLED if necessary, if not put the plates aside (fridge) until a new supply of CLED can be brought in - if this will occur rapidly. If it will take longer consider shipping these specimens to another laboratory.
Agar, or agar-agar, is not a grain, but rather an extract of seaweed. Agar translates to German as Agar-Agar Try whole- or health-food stores
Agar-agar
an extract of seaweed
Approximately 2 teaspoons of agar agar powder is equivalent to 7 grams.
No, agar agar does not contain collagen. Agar agar is a gelatinous substance derived from seaweed, while collagen is a protein found in the connective tissues of animals.
Agar is derived from seaweed and is often used in Japanese desserts
Agar agar can be used as a substitute for gelatin in recipes that call for it. Agar agar is a plant-based alternative that works similarly to gelatin in setting and thickening recipes.

Agar-agar can be used in vegan cooking as a gelatin substitute to make desserts like puddings, jellies, and fruit gels. It can also be used to thicken soups, sauces, and even as a binder in vegan burgers or meatballs. Additionally, agar-agar can be used to create vegan versions of traditional Asian dishes like agar-agar noodles or agar-agar sushi rolls.
