WebNov 4, 2024 · Figure 3.2. 3: Gram-staining is a differential staining technique that uses a primary stain and a secondary counterstain to distinguish between gram-positive and gram-negative bacteria. First, crystal violet, a primary stain, is applied to a heat-fixed smear, giving all of the cells a purple color. WebIn Gram-negative bacteria, the cell wall is surrounded by an outer membrane that contains lipopolysaccharides and lipoproteins. Porins are proteins in this cell membrane that allow substances to pass through the outer membrane of Gram-negative bacteria. In Gram-positive bacteria, lipoteichoic acid anchors the cell wall to the cell membrane. WebThe gram stain, originally developed in 1884 by Christian Gram, is probably the most important procedure in all of microbiology. It has to be one of the most repeated procedures done in any lab.
