What is the stainning method called that can distinguish between two different types of eurobacteria?
I believe what you're looking for is the stain that can differentiate between Gram-negative and Gram-positive bacteria: two types of eubacteria. So the staining method is called the Gram method. Crystal violet will remain trapped in Gram-positive bacteria due to their thicker cell walls, causing them to stain purple. Crystal violet can be washed out of Gram-negative cell walls after alcohol treatment to remove their outer lipid membrane, and the cells can be counterstained with a red, positively charged stain. In the end, Gram-positive bacteria will look purple, and Gram-negative bacteria will look red. See Wikipedia for more details.
