BIOS 225 Lab Report Week 4- Gram Staining Introduction: Gram staining is a method of staining used to differentiate bacterial species into two large groups, gram-positive and gram-negative. Gram staining differentiates bacterial species by the chemical and physical properties of their cell walls by detecting peptidoglycan, which is present in the cell wall of gram-positive bacteria. Gram-positive retain the crystal violet dye while gram-negative does not. Gram positive will appear purple and...
