Hello students, let's see the answer.
00:02
First we are going to build of the column.
00:05
First one is after crystal violet, after crystal violet, the gram positive bacteria, it will retain the primary stain crystal violet.
00:22
And they does not take the secondary stain saffronin.
00:30
In gram negative bacteria after crystal violet adding, the gram negative bacteria does not retain the crystal violet stain.
00:50
Then after grams iodine, in gram positive bacteria, after adding gram ziodin, the gram zyodin act as a mordant or an agent that fixes the crystal violet to the bacterial cell wall.
01:31
In gram negative bacteria, there is no philipateria.
01:40
The crystal boiler to the bacterial cell wall.
01:56
Then after alcohol, the alcohol is penetrate the cell wall of gram negative cell and remove the crystal violet and iodine complex.
02:17
In gram -positive bacteria, they applying to decolorizer to long will remove die complexes from the gram -positive cell wall...
