What color is gram negative stain and gram positive stain if you forget to apply iodine?

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.


In a gram stain if alcohol is left out what color would a Gram-negative bacterium turn out?

If alcohol is left out during a Gram stain procedure, a Gram-negative bacterium would appear purple after the addition of the counterstain (safranin). This is because the alcohol step is necessary to remove the crystal violet-iodine complex in Gram-positive bacteria, but without it, the purple color remains in both Gram-negative and Gram-positive bacteria.


Are compounds that consist only of a cromophore considered to be stains?

No, compounds consisting only of a chromophore are not considered stains.

The auxochrome is necessary for the stain to effectively bind to the material and impart color.

Is coffee a true biological stain?

The difference between a biological stain and a compound imparting color is more one of use rather than effect.
