Acid-fast stain is the stain used to identify Mycobacterium tuberculosis, as its cell wall contains a high concentration of mycolic acid, which makes it impermeable to most stains. Acid-fast staining makes the cell wall more permeable to retain carbol-fuchsin dye, which imparts a bright red color to the bacteria under the microscope.
