You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles appear, indicating the presence of a particular enzyme that the bacterium produces. What type of identification test does this exemplify?

A) Biochemical test

The complete question is as follows:

You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles appear, indicating the presence of a particular enzyme that the bacterium produces. What type of identification test does this exemplify?

A) Biochemical test

B) Immunochromatography

C) Microarray

D) Precipitation test

Biochemical testing is a useful method using which one can identify the bacteria upto the genus and species level. Each organism identified through biochemical testing has its specific biochemical reaction that acts as a fingerprint for its identification. The reason why different biochemical reactions are produced by different bacterial species is because the different species possess their own set of DNA that encodes for unique set of proteins in each of them.Therefore, the production of bubbles on addition of hydrogen peroxide in an inoculum of bacterium due to presence of a particular enzyme unique to the bacterium is a type of biochemical identification test.
