The process of applying Grams stain is as follows: the bacteria are stained with a violet color and treated with Grams solution (1 take off iodine, 2 separate potassium iodide, and 300 parts water). ethyl group alcoholic drink is then applied to the medium; the bacteria forget any preserve the blue color of the original dye or they...
