Ru.go.si.mo.no.spo'ra, L. adj. rugosus, rugose, Gr. adj. monos, single, Gr. fem. n. spora a seed and, in bacteriology, a spore, N.L. fem. n. Rugosimonospora, a bacterium forming single, rugose spores.

Actinobacteria / Actinobacteria / Micromonosporales / Micromonosporaceae

Nonfragmenting vegetative mycelium, aerial hyphae are not produced. Single spherical and nonmotile spores, with rugose surface, formed on the substrate mycelium, are 0.7–0.8 µm in diameter. Gram-positive. Aerobic and non-acid-fast. Acidophilic. Optimal temperature is 22–28 °C. Gelatin, casein, and starch are hydrolyzed. H₂S is produced. Nitrate is not reduced. Xylose, mannose, and glycerol are used as sole carbon source. Peptidoglycan contains hydroxy-diaminopimelic acid (3-OH DAP) plus glutamic acid, glycine, and alanine. Acyl type of the peptidoglycan is N-glycolyl. Galactose, arabinose, and xylose are present in whole-cell hydrolysates. Predominant menaquinone is MK-9(H₈), MK-9(H₆) present in minor amounts. Different predominant fatty acids (mainly saturated) found in the described species. Major polar lipids are phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine, methyl-phosphatidylethanolamine, and an unknown aminophospholipid. Natural habitat is soil.

DNA G +C content (mol%): 72–73 (HPLC).
