Being able to differentiate bacterial species is important for a host of reasons. While molecular techniques can determine the specific species, even without getting into the molecular nitty gritty, there are phenotypic differences between groups of bacteria that can be used to differentiate them. One such useful classification – if a bacterium is Gram positive or Gram negative - is based on the structure of bacterial cell walls.

What's the difference between Gram-negative Bacteria and Gram-positive Bacteria? Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan a...
