Phylum Actinobacteria, Class Actinobacteria, Order Actinomycetales, Suborder Corynebacterineae, Family Mycobacteriaceae, Genus
Mycobacterium, Mycobacterium hodleri Kleespies et al. 1996.
Species description is based on a single isolate.
Acid-fast rods (1.0 x 1.8-2.3 μm). Some cells occur in V-form and in palisades. Non-
spore-forming. Non-motile. Gram-positive.
Colonies are smooth, but with some rough variants, and are scotochromogenic,
producing a saffron yellow pigment on Middlebrook agar and a chrome yellow
pigment on Trypticase soy broth agar. Growth occurs at temperatures between 18
and 28 ºC. No growth at 37, 42, and 45 ºC. Aerobic. Chemoorganotrophic. No growth
on MacConkey agar without crystal violet or in 5% NaCl media.
Isolated from a fluoranthene-contaminated site near Jiilich, Germany.
Resistant to isoniazid (10 μg/ml) and picrate (0.2%) . Susceptible to hydroxylamine (500 μg/ml).
