Scanning electron micrograph of Mycobacterium tuberculosis - Source:3Autotroph/Mixotroph
Mycobacteria are aerobic actinomycetes 4 that are widespread in the environment 5. They possess the mycolata morphotype and usually form slightly curved or straight rods 4, which can appear in chains or as individual cells 5. Mycobacterium are often involved in foaming events 6. While they are heterotrophs some strains are able to grow autotrophically 4. Mycobacteria are metabolically versatile organisms, as they are able to grow on a variety of carbohydrates, alcohols, organic acids, hydrocarbons 4, ketones and carboxylic acids 7.
