Actinomadura is one of four genera of Actinomycetota that belong to the family Thermomonosporaceae. It contains aerobic, Gram-positive, non-acid-fast, non-motile, chemo-organotrophic actinomycetes that produce well-developed, non-fragmenting vegetative mycelia and aerial hyphae that differentiate into surface-ornamented spore chains. These chains are of various lengths and can be straight, hooked or spiral.^[3] The genus currently comprises over 70 species with validly published names with standing in nomenclature,^[1] although the species status of some strains remains uncertain, and further comparative studies are needed.^[3]

Members of the genus are not characterized chemotaxonomically by type III/B cell walls (meso-diaminopimelic acid and madurose are present) with peptidoglycan structures of the acetyl type. The predominant menaquinone types are MK-9(H4), MK-9(H6) and MK-9(H8). The phospholipid pattern is PI (diphosphatidylglycerol and phosphatidylinositol are present as major phospholipids) and the fatty acid pattern is type 3a (branched saturated and unsaturated fatty acids plus tuberculostearic acid).^[4]
