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 is the function of nessler's reagent?
nessler's reagent
What chemical reagent of protein?
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
Are there limitations to the oxidase test?
There are none.
What reagent is used to test for glucose and starch?
Glucose meter and test stripe

media used for oxidase test is non selective media

What is the function of Fehling's test?
Fehling's test is used to differentiate between aldehyde and ketones group. An aldehyde group will react with Fehling's reagent to give cuprous oxide resulting in a red precipitate. A Ketone group will not react with Fehling's reagent.

Glucose meter and test stripe
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 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.
Does E. coli test positive for oxidase?
no
What is another test used for the identification of Staphylococcus aureus?
oxidase test.
