This is simply important in order to have accurate staining results. If this is not followed, the process of the staining will result to false positives or false negatives.
Anthrax is a gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure.
Endospores have a unique structure with thick layers of protein and peptidoglycan that resist the staining process used in Gram staining. The dye used in Gram staining is unable to penetrate these layers, resulting in endospores not taking up the stain. Specialized staining techniques, such as the Schaeffer-Fulton method, are required to visualize endospores.
Staphylococcus epidermidis is a Gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure. This results in a purple color under the microscope.
Removing the mordant from the Gram staining procedure would result in poor differentiation between Gram-positive and Gram-negative bacteria. The mordant helps to fix the crystal violet stain inside the thick peptidoglycan layer of Gram-positive bacteria, leading to their retention of the purple color. Without the mordant, both Gram-positive and Gram-negative bacteria may appear pink after the decolorization step, making it difficult to distinguish between the two groups.
The phylum containing bacteria with gram-positive cell walls is Firmicutes. These bacteria have a thick layer of peptidoglycan in their cell walls, which retains the crystal violet stain in the Gram staining procedure.
Gram, Ziel-Nielsen
Gram-negative bacteria do not retain the purple color in the Gram staining procedure because their cell walls have a thinner layer of peptidoglycan, which does not hold the crystal violet dye as effectively as the thicker peptidoglycan layer in Gram-positive bacteria.
Anthrax is a gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure.
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.
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

Sodium bicarbonate is used to adjust the pH of the staining solution in the Gram stain procedure. Merthiolate is used as a mordant to enhance the crystal violet staining in the Gram stain. Together, they help differentiate between Gram-positive and Gram-negative bacteria based on their cell wall characteristics.

Gram staining is the initial procedure, crutial in determining whether the unknown organism is Gram positive or Gram negative. Once the type is concluded, it is earsier to chose which type of antibiotic will be best to kill the bacterial growth.
The scientific name for true Gram-positive bacteria is Firmicutes. These bacteria have a thick peptidoglycan cell wall that retains the crystal violet stain in the Gram staining procedure.
Staphylococcus epidermidis is a Gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure. This results in a purple color under the microscope.
gram staining is a biochemical method of identifying bacteria in a more specific way.Thus it is important to differentiate gram positive and gram negative bacteria.
