Gram positive bacteria lack an outer membrane, have a thick layer of peptidoglycan, contain teichoic acid, and lack mycolic acid.
Gram Positive Bacteria- Gram-positive microorganisms are identified by the color they take on when stained. The staining technique was invented by Hans Christian Gram in 1884. The peptidoglycan cell wall present in gram-positive organisms retains the crystal violet dye used in the staining process.
Peptidoglycan cell wall- In most bacterial species, the cytoplasmic membrane is encased in a hard material called peptidoglycan. It helps maintain cell shape throughout the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycans has a significant role in controlling bacterial cell division.
