WebThe Gram staining procedure is a laboratory technique used to differentiate bacterial species based on their cell wall characteristics. It involves a series of sequential steps as follows: Step 1: Preparation of the smear: A small amount of the bacterial sample is placed onto a microscope slide and allowed to air-dry. WebBacterial cell walls are characterized by the presence of peptidoglycan, whereas those of Archaea characteristically lack this chemical. Algal cell walls are similar to those of plants, and many contain specific …

WebJan 22, 2024 · This dehydrates the peptidoglycan layer in the bacterial cell walls, causing it to shrink and tighten. In gram-positive bacteria, the crystal violet dye is trapped inside the thick, peptidoglycan layer. In gram-negative bacteria, the thin peptidoglycan layer is unable to hold onto the dye, and it leaks out of the cell wall. ...
