Accepted Answer

The Gram staining procedure is a differential staining technique which differentiates bacteria based on their cell wall structure, specifically the presence or absence of peptidoglycan. It is used to differentiate between Gram-positive bacteria, which have a thick layer of peptidoglycan, and Gram-negative bacteria, which have a thinner layer of peptidoglycan surrounded by an outer membrane.
