NocardiopsisRANK: GenusTAXONOMY: Bacteria -> Terrabacteria group -> Actinobacteria -> Actinobacteria -> Streptosporangiales -> Nocardiopsaceae -> Nocardiopsis OVERVIEW: Gram-stain-positive, aerobic, chemo-organotrophic, nonacid-fast, nonmotile filamentous actinomycetes. Substrate mycelium is well developed and hyphae are long and densely branched. Fragmentation into coccoid and bacillary elements may occur. Aerial mycelium is well developed and sparse-to-abundant; aerial hyphae are long, branched, straight to flexuous, or irregularly zig-zagged, completely fragmenting into spores of various lengths. Spore surface is smooth. Wall peptidoglycan contains meso-diaminopimelic acid and the muramic acid of the peptidoglycan is acetylated. No diagnostic sugars are found in whole-organism hydrolysates. Mycolic acids are absent. Major phospholipids are phosphatidylcholine, phosphatidylmethylethanolamine, phosphatidylglycerol, and phosphatidylinositol, with small amounts of diphosphatidylglycerol. Menaquinones are predominantly variably hydrogenated with ten isoprene units (MK-10), with minor amounts of the MK-9 and/or MK-11 series. The main fatty acids are branched and 10-methyl-branched fatty acids, 14-methyl-heptadecanoic acid, and 14-methyl-hexadecanoic acid. Growth temperature range is 10–45°C. Widely distributed in saline and alkaline soils, and found in compost, vegetable matter, indoor environments, and clinical material of animal and human origin. DNA G+C content (mol%): 64–69.
