Quizplus · Accepted Answer

Organisms will resist Gram staining when they contain a waxy outer coat composed of mycolic acid, which is found in acid-fast bacteria such as Mycobacterium tuberculosis. The waxy coat acts as a barrier, preventing the stain from penetrating the cell wall and producing a visible result. Peptidoglycan is a component of the cell wall in bacteria and is stained by the Gram stain. Lipopolysaccharide is a component of the outer membrane in Gram-negative bacteria and is also stained by the Gram stain. Cellulose is a polysaccharide that is not found in bacteria and is therefore not relevant to the question.
