PlanomonosporaRANK: GenusTAXONOMY: Bacteria -> Terrabacteria group -> Actinobacteria -> Actinobacteria -> Streptosporangiales -> Streptosporangiaceae -> Planomonospora OVERVIEW: Substrate and aerial mycelium developed on various agar media. Substrate hyphae (0.6–1.0 µm in diameter) are nonfragmenting, irregularly branched, and occasionally septated. Aerial hyphae are sparsely branched and rarely septated. Organisms are Gram-stain-positive and non-acid-fast. Cylindrical to clavate sporangia (1.0–1.5 µm × 3.5–5.5 µm) are formed in bundles on the aerial mycelium, arranged either in narrow parallel rows resembling rows of bananas or in an open palm leaf pattern. Each sporangium contains a single spore. Spores (zoospores) are oblong to fusiform and motile by means of peritrichous flagella. Growth under aerobic conditions. Colonies developed on complex agar media are raised or flat with rugose or smooth surfaces. Substrate mycelium may be grayish yellow, light orange, rose, yellowish pink, or violet-brown. Aerial mycelium is white, grayish white, light rose, or pink. Chemoorganotrophic, mesophilic, grows well at 28–37°C and from pH 7.0–8.0. DNA G+C content (mol%): 72 (Tm). Type species: Planomonospora parontospora |
