“…This observation may explain the contradictory reports regarding the relationship between Thermomonospora and Nocardiopsis on the basis of 16s rRNA sequence analysis (9, 46, 50). The close phylogenetic relationship amongst the three Thermomonospora species and Nocardiopsis is further supported by their sharing of a menaquinone with unusually long partially saturated isoprenyl side chains and a preference for alkaline growth conditions (29,30,36). Although Thermomonospora chromogena is phylogenetically distant from other members of the family Streptosporangiaceae, they are very similar in chemotaxonomic properties (8,20).…”

A new species of the genus Nocardiopsis, for which we propose the name Nocardiopsis lucentensis sp. nov. (type strain, strain DSM 44048), was isolated from a salt marsh soil sample near Alicante, Spain. Whole-cell hydrolysates contain the meso isomer of diaminopimelic acid and no characteristic sugar; thus, the cell wall composition is type 111. Menaquinone MK-lO(H,) is the major menaquinone, and the phospholipid type is type PI11 (phosphatidylcholine present). Spore chains are rectiflexibilis, and in the early stages of sporulation zig-zag-shaped aerial hyphae are observed. This microorganism produces compatible solutes of the ectoine type and is characterized by a yellowish to yellowish brown substrate mycelium and a white aerial mycelium. This organism exhibits only 40 to 50% DNA relatedness to other Nocardiopsis spp.

A total of 15 strains of the genus Nocardiopsis were characterized chemotaxonomically and physiologically in an attempt to resolve their taxonomy. These strains fell into two h a , which differed in cell wall composition and menaquinone, phospholipid, and fatty acid patterns. Ten of the strains assessed in this study belong to the genus Nocardiopsis and can be assigned to five species on the basis of their physiology. Nocardiopsis dussonvillei subsp. dassonvillei is heterogeneous; N. dassonvillei remains centered on the type strain (strain DSM 43111), and the remaining strains form a new subspecies, Nocardiopsis albus subsp. albus sp. nov. (type strain, strain DSM 43377). The former N. dussonvillei subsp. prasina is recognized as a close relative of the latter organism and is designated N. dbus subsp. prasina comb. nov. Two formerly misclassified species of the genus Actinomyces not on the Approved Lists are revived as Nocardiopsis alborubidus sp. nov. and Nocardiopsis listen' sp. nov. The remaining five Nocardiopsis species (Nocardiopsis coeruleofusca, Nocardwpsis Java, Nocardiopsis longispora, Nocardiopsis mutabilis, and Nocardiopsis syringae) appear to be misclassified, and, on the basis of their similarities to the type species Saccharothrix australiensis, reclassification in the genus Saccharothrix should be considered. Nocardiopsis atra and Nocardiopsis africana were not included in this study.Lechevalier and Lechevalier showed that all members of the family Streptomycetaceae contain LL-diaminopimelic acid in their cell walls (17). Later studies of Pridham and Lyons (29) and Kroppenstedt and Kutzner (11) on the cell walls of more than 500 streptomycete species showed that some of the streptomycetes were incorrectly classified because the meso isomer and not the LL isomer of diaminopimelic acid was detected in whole-cell hydrolysates. Some of these strains lack the diagnostic sugars defined by Lechevalier and Lechevalier (17) and seem to be closely related to members of the genus Nocardiopsis. Therefore, we examined these so-called "DL streptomycetes" by using physiological and chemotaxonomic methods. For comparison we included all of the known members of the genus Nocardiopsis except Nocardiopsis antarcticus (1), for which only the fatty acids were analyzed, and "Nocardiopsis atra" (W. D. Celmer et al., U.S. patent 55194C, July 1980), which was not available to us. Nocardiopsis africana DSM 43748 was not included in our investigations because this organism has already been reclassified by Poschner et al. (25) as a member of the Actinomadura pusilla group. MATERIALS AND METHODSThe strains which we investigated and their source are listed in Table 1. Most of the Nocardiopsis species were grown at 28°C on CYC agar (Czapek-Dox agar supplemented with 2.0 g of yeast extract per liter and 6.1 g of Casamino Acids per liter) because sporulation was best on this medium. One strain, "Streptomyces listeri" DSM 40297T (T = type strain), was cultivated on Hickey-Tresner agar (8, 9). The strains that belong to the ge...
