type (type III; meso-diaminopimelic acid), a similar menaquinone profile in which MK-9(H6)is predominant, and fatty acid profile type 3a. The presence of the diagnostic sugar madurose is variable, but can be found in most species of this family. The polar lipid profiles are characterized as phospholipid type PI for most species of ''Thermomonospora'', ''Actinomadura'' and ''Spirillospora''. The members of ''Actinocorallia'' are characterized by phospholipid type PII. The G+C content of the DNA lies within the range 66±72 mol%. The pattern of 16S rRNA signatures consists of nucleotides at positions 440 : 497 (C–G), 501 : 544 (C–G), 502 : 543 (G–C), 831 : 855 (G–G), 843 (U), 844 (A) and 1355 : 1367 (A–U). The type genus is ''Thermomonospora''
