Lowenstein-Jensen medium is specifically designed for the cultivation of slow-growing Mycobacterium species. This medium contains malachite green, which inhibits the growth of other bacteria that may be present in the sample, and glycerol, which is utilized by Mycobacterium species as a carbon source. The other media listed (blood agar, MacConkey agar, and Sabouraud's agar) are not selective for Mycobacterium species and would not facilitate the growth of these organisms.
