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.
Lactococcus Lactus is a gram positive bacteria and therefore retains the darker staining and therefore shows on a gram stain as dark blue/violet colour. This is because the thick peptidoglycan cell wall retains the primary crystal violet stain.
Anthrax is a gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure.
