Apply the crystal violet for one minute, flush with running water (gently), then apply Gram's iodine for one minute, flush gently with running water, immediately submerge in alcohol (perferably isopropyl) and gently agitate for about 10 seconds, gently flush with running water, and then apply a counter-stain (saffranin) for about 2 minutes, flush with running water gently and blot dry with bibulus paper.

What is the staining process for separating bacteria?
This is known as a gram test.
What is the value of gram staining?
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.

Why gram staining classified as differential staining?
Differential staining is the procedure that are used to distinguish organism based on their staining properties. Use of gram stain divide bacteria into two classes - gram positive which retain crystal violet stain purple colour, gram negative which lose their crystal violet and give pink colour. By this method we can differentiate two different types of bacteria having different cell wall composition that is the reason gram staining used widely as differential staining

Why is gram staining important?
It tells the microbiologist/clinician facts about the cell wall construction of the bacterium. This then indicates which antibiotics to prescribe if you are trying to get rid of a bacterial infection.

What is staining for candida albicans?
gram positive
Why you do staining?
Staining is done to help determine what the sample is. It makes it visible under a microscope and it gives some information about the structure of the cell. A positive Gram stain means that the cell has a thick peptidoglycan layer.
What are the colony characteristics and Gram staining of bacillus circulans?
Gram Positive Rods
Is gram staining special staining?
yes it is a special staining like other types....its importance is that one can identify the type of bacteria........
