Which of the following bacteria contains mycolic acid in the cell wall
Correct Answer: Mycobacteria
Description: Mycobacterium are slender rods that sometimes show branching, filamentous forms resembling fungal mycelium. In liquid cultures, they form a mould like a pellicle. they do not stain readily, but once stained, resist decolourisation with dilute mineral acids, due to the presence of mycolic acid in their cell wall. They are called acid-fast bacilli. Mycobacterium are slow-growing, aerobic, non-motile, non-capsulated and non-sporing.
