Seven strains of armadillo‐derived mycobacteria (ADMs) were encouraged to produce the lipid‐soluble siderophore mycobactin when grown under conditions of iron limitation. These compounds have recently been shown to be excellent chemotaxonomic markers for the mycobacteria being both species‐specific and highly conserved. Characterization of the mycobactins was carried out by thin‐layer chromatography (TLC) and high‐performance liquid chromatography (HPLC). Examination of the mycobactins isolated from the ADM strains showed them to be heterogeneous. Four strains synthesized mycobactins closely resembling those of the M. avium‐intracellularescrofulaceum (MAIS) complex, whereas the remaining three strains formed mycobactins which differed in structure to those of any other mycobacterium previously examined.
