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.
What is Oxidase test results for bacillus subtilis?
It is NEGATIVE
Are all aerobic bacteria oxidase positive?
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
What is Urease test results for bacillus cereus?
Bacillus cereus is oxidase negative -
Why is the Glucose Oxidase test a more specific test for urinary glucose that Benedict's test?
the tests are more simple and sensitive than Benedict's tes
Are there limitations to the oxidase test?
There are none.
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.
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.
Why is it advisable to include a known oxidase-positive control 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.
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.
What is selective test?
selective type test is not a hard test if youstudy hard
Does E. coli test positive for oxidase?
no
What is another test used for the identification of Staphylococcus aureus?
oxidase test.
The oxidase test is used to differentiate among which groups of bacteria?
Differentitate among members of the genera Neisseria and Pseudomonas which are oxidase positive and Enterobacteriaceae which are oxidase negative.
What is the function of the test reagent in the oxidase test?
The ability of bacteria to produce cytochrome oxidase can be determined by the addition of the test reagent p-aminodimethylaniline oxalate to colonies grown on a plate medium.
Why is an oxidase test performed on a culture before using API 20E and Enterotube II to identify the culture?
API 20E and Enterotube II are for the identification of oxidase- negative bacteria. If the oxidase test is positive, these two methods of identification would be useless.
What is selective type test?
Selective test is a very very hard test. Its only for 0.01% of Australian children can pass this test.
