A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.

Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
