What is Urease test results for bacillus cereus?

Bacillus cereus is positive for the urease test, meaning it can break down urea to produce ammonia and increase the pH of the media. This can be observed by a color change in the media from yellow to pink or magenta.


What are the common biochemical tests used in identification of bateria?

The most common biochemical tests are gram stain, oxidase, catalase and coagulase tests. However, there are literally hundreds of biochemical tests that are commonly used to identify bacteria. For further information, check out MicrobeID.com, where you can find identification methods, keys, probabilistic databases, selective and differential media guides, as well as book reviews releated to bacterial identification. I would also recommend Bergey's Manual of Deterministic Bacteriology.


Why is It advisable to include an oxidase positive control organism in any test of an unknown organism?

It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.


Is Alcaligenes faecalis oxidase positive?

yes and no, sometimes it comes out positive and sometimes it comes out negitive


What is Oxidase test results for bacillus subtilis?

Bacillus subtilis is positive for the oxidase test. This means that it has the enzyme cytochrome c oxidase, which is needed for the bacterium to produce energy through aerobic respiration. The positive result is indicated by the appearance of a color change (usually dark purple) on the test strip after adding the reagent.

What is the Lactococcus lactis ssp lactis oxidase test result?

The oxidase test result for Lactococcus lactis ssp lactis is negative. This bacterium lacks the enzyme cytochrome c oxidase that is needed to produce a positive result in the oxidase test.


What is the function of the test reagent in the oxidase test?

The test reagent in the oxidase test contains a substrate that changes color when it is oxidized by cytochrome oxidase, an enzyme present in certain bacteria. The color change indicates the presence of the enzyme, helping to differentiate between oxidase-positive and oxidase-negative bacteria.


Is coryne bacterium is oxidase positive?

No, Corynebacterium species are typically oxidase-negative. This means they do not produce the enzyme cytochrome c oxidase, which is essential for the oxidase test.


What is Urease test results for bacillus cereus?

Bacillus cereus is positive for the urease test, meaning it can break down urea to produce ammonia and increase the pH of the media. This can be observed by a color change in the media from yellow to pink or magenta.


Why is it advisable to include an oxidase-positive control organism in any test of an unknown organism?

It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.


The oxidase test is used to differentiate among which groups of bacteria?

The oxidase test is used to differentiate bacteria based on their ability to produce cytochrome c oxidase enzyme. It helps to differentiate between oxidase-positive bacteria, such as Pseudomonas and Neisseria, and oxidase-negative bacteria, such as E. coli and Enterococcus.


Does E. coli test positive for oxidase?

no


What is selective test?

selective type test is not a hard test if youstudy hard


What is another test used for the identification of Staphylococcus aureus?

oxidase test.


Why is it advisable to include a known oxidase-positive control in any test of an unknown organism?

Including an oxidase-positive control in a test of an unknown organism helps to confirm the presence of the enzyme oxidase in the test system. This control provides a baseline for comparison with the unknown organism to determine if it also produces oxidase. This is particularly important in biochemical testing to accurately identify the unknown organism based on its metabolic properties.


Give explanation why the Oxidase test identifies the presence of cytochrome c oxidase and not the other electron carriers?

An oxidase test relies on a reagent that will change colors when it is oxidized. The reagent used in the test only reacts to cytochrome c oxidase by acting in place of oxygen to receive electrons from the cytochrome.


What Two genera that are oxidase positive?

Neisseria, Alcaligenes, Moraxella, and Pseudomonadaceae are genera of oxidase positive microorganisms.
