In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. ... This is due to the difference in the structure of their bacterial cell wall. Gram-positive bacteria do not have an outer cell membrane found in Gram-negative bacteria.✔✔✔
☞ GRAM POSITIVE BACTERIA :-
1) cell wall is made up of peptidoglycan + teichoic acid.
2)Stain remain presistant.
3)cell wall single layer.
☞GRAM NEGATIVE BACTERIA :-
1)cell wall is made up of peptidoglycan .
2) statin remove because stain is soluble in water and insoluble in liquid .
3) An additional layer of glycolipid is present in the cell wall.
