Urease hydrolyzes urea to form what?
Urease breaks down the compound urea into ammonia and carbon dioxide.
Is proteus urease positive?
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.
What is the color of urease agar when inoculated with an urease negative organism?
The agar slant will remain the original color (yellow). However, most labs use the broth.Two media types are commonly used to detect urease activity. Christensen’s urea agar is used to detect urease activity in a variety of microorganisms. Stuart’s urea broth is used primarily for the differentiation of Proteus species.
Is enterococcus faecalis positive or negative with the urea broth test?
It is urease positive .It possesses the enzymes urease which hydrolyses urea to form ammonia. As a result the pH of the medium used for detection of urease enzyme (Urea Broth) increases and shows bright pink colour, since phenol red is bright pink in alkaline conditions.
What is the main advantage of the urea disk over both broth tubes and slants with respect to the detection or urease?
It takes a lot less time.
Urease hydrolyzes urea to form what?
Urease breaks down the compound urea into ammonia and carbon dioxide.
What enzyme is responsible for metabolizing urea?
Urease!
What is the substrate for urease?
Urea which is protein substrate
What is the function of urease?
Hydrolysis of urea to carbon dioxide and ammonia is catalyzed by the enzyme urease.
What is urease test in microbiology?
When determining the ability of a bacteria to degrade urea by means of the enzyme urease. To diagnose H. pylori and identification of the genus Proteus, Providentia, Kelbsiella, and Morganella by their fast urease activity.
What does urease positive mean?
Urease positive means that an organism can produce the enzyme urease, which reacts with urea to produce ammonia and carbon dioxide. This reaction can be detected by the change in pH of the media, typically turning it pink or red. Urease positivity is often used in microbiology to help identify certain bacterial species.
Is proteus urease positive?
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.
What is the explanation for the mechanism of urease activity?
"Urease is a hydrolytic enzyme that attacks the nitrogen and carbon bond in amide compounds such as urea and forms the alkaline end product ammonia."
Urease?
breaks down urea to produce ammonia, which neutralizes stomach acid in the immediate environment

Of what value is urease to helicobacter?
H. pylori are able to fight the stomach acid with urease they release. Urease converts the urea in the stomach into bicarbonate and ammonia, which are strong bases. This creates a cloud of acid-neutralizing chemicals around the H. pylori, protecting it from stomach acid.
Is urea the same thing as ammonium nitrate?
Yes.
