Morphology | Actinomadura |
CELLULAR |
Staining | Gram positive |
Morphology | Extensively branching vegetative hyphae, forming a dense, non-fragmenting substrate mycelium; aerial mycelium moderately developed or absent. When aerial mycelium is lacking colonies have a leathery or cartilaginous appearance. The aerial mycelium at maturity forms short or occasionally long chains of arthrospores. Spore chains straight, hooked (open loops), or irregular spirals (1-4 turns). Spore surface smooth or warty. Colour of mature sporulated aerial mycelium white, gray to brownish, yellow, red (pink and rose), blue, greenish, or violet |

Unique features | Cell wall contains meso-2,6- diaminopimelic acid (meso-DAP) as principal diamino acid and major amounts of galactose in most strains. Whole-cell hydrolysates contain the sugar madurose. Mycolic acids absent. Menaquinones are predominantly of the MK-9(H4) and MK-9(H6) type. Additional menaquinones of the MK-9(H2) and MK-9(H8) types occur.. |
