It will hold the primary stain of violet.
gram positive Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this bacterium is gram (+).
Crystal violet is the primary stain in the Gram's stain procedure, used to color all bacteria cells purple. This helps differentiate between Gram-positive bacteria (which retain the violet color) and Gram-negative bacteria (which lose the violet color when decolorized with alcohol).
Gram-positive bacteria will retain the crystal violet stain and appear purple under a microscope after being stained. This is due to the thick peptidoglycan layer in their cell walls that retains the stain during the washing step of the Gram staining procedure.
Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.
The color of a gram-negative stain is pink or red. This staining technique is used to differentiate bacteria based on their cell wall composition, with gram-negative bacteria retaining the pink/red color after staining.
The answer to whether HIV gram-stain positive or negative is that HIV gram-stain is negative. They retain the light red or pink color after the stain.
gram positive Exactly. When doing a gram stain on B. subtilis, this bacterium resists decolorization (keping the first stain and NOT taking on the color of the secondary stain). Therefore, this bacterium is gram (+).
If iodine is not applied, both the gram-positive and gram-negative stains will appear to be gram-negative. The iodine acts as a mordant that helps to fix the crystal violet stain in the gram-positive bacteria, making them appear purple. Without iodine, the crystal violet stain can be easily washed out of both gram-positive and gram-negative bacteria, resulting in a pink or red color.

gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.
Gram-positive does not refer to a positive charge, but to the purple color of the stain. Gram-negative bacteria do not retain the purple dye and are instead red in color.
Yes, the results agreed with the gram stain information in the textbook. The gram stain showed purple color for Gram-positive bacteria and pink color for Gram-negative bacteria, confirming their respective characteristics.
If using a gram stain, they will turn Crystal Violet.
Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.
