Mycolic acid. Mycolic acids are long fatty acids found in the cell walls of the mycolata taxon, a group of bacteria that includes Mycobacterium tuberculosis, the causative agent of the disease tuberculosis. They form the major component of the cell wall of mycolata species.
Additionally, cocci and bacilli can be classified by the structure of their cell wall. Bacteria that have a thick layer of a substance called âpeptidoglycanâ in their cell wall will pick up a crystal violet (Gram) stain and are thus called â Gram-positive â bacteria. These bacteria appear dark blue or purple under the light microscope because the peptidoglycan traps a violet stain.
