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.

Can rubbing alcohol stain fabric?

What is the purpose of alcohol used in the gram stain?
The alcohol is a decolorizer. In gram negative organisms, the small amount of peptidoglycan can't hold onto the crystal violet in the presence of the alcohol and so becomes decolorized. The gram positive organisms have a much thicker peptidoglycan layer, and so the crystal violet stays in even with washing by alcohol.
What is the decolorizing agent in the acid fast stain?
