Would a false positive from the reaction between the inoculating loop and hydrogen peroxide be caused by poor specificity or poor sensitivity of the catalase test system?

The false positive from the reaction of hydrogen peroxide and the inoculating loop would be caused by poor specificity. The formula for specificity is TN/TN+FP.

What substrate does catalase work on?
Catalase Hydrogen peroxide -----------------> Water + Oxygen.
How do you know that the raw foods contained catalase?
When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water. The bubbles you see in the foam are pure oxygen bubbles being created by the catalase.
What reagent detects catalase?
Hydrogen peroxide( 3% H2O2)
What is the job of the catalase enzyme?
Catalase breaks down toxic hydrogen peroxide in living organisms (in both plants and animals) into water and oxygen. 2H2O2 (reaction of catalase) produces 2H2O + O2
Is catalase usually considered a virulence factor of bacteria?
Yes, it is. Staphylococci are catalase positive and it is favorable to their survival as catalase can reduce hydrogen peroxide so as to resist the oxidative pressure from the host.
Does poor sensitivity or poor specificity cause a false positive from the reaction between inoculating loop and hydrogen peroxide?
Catalase is the enzyme that catalyzes the breakdown of hydrogen peroxide, which in result, turns into water and oxygen. However, if catalase is presence in the medium, it may lead to false positive results.

no

Catalase Hydrogen peroxide -----------------> Water + Oxygen.
What effect does catalase have on the breakdown of hydrogen peroxide?
Catalase converts hydrogen peroxide into water and oxygen.
What enzyme acts on hydrogen peroxide in living organisms?
Catalase Catalase
What chemical reaction degrades hydrogen peroxide in the presence of catalase?
Catalase is the endozyme that then degrades hydrogen peroxide into water and oxygen
Enzymes that cause hydrogen peroxide to decompose are called?
The enzyme catalase causes the decomposition of water into hydrogen and oxygen inside cells.
Hydrogen is a substrate of the enzyme catalase?
Peroxide
What hydrogen is a substance of the enzyme catalase?
peroxide

What are the reagents used in the catalase test?
hydrogen peroxide
