If you have done your gram stain properly the mycobacterium will appear to be gram positive, however an acid fast stain is necessary because of the extremely long hydrocarbon chains and the high lipid content in the cell wall. The high lipid content makes the cell wall waxy. Both of these make the cell fairly impermeable to stains.
