The strain was identified using a polyphasic taxonomic approach. The strain grew slowly on most media tested, producing small amounts of aerial mycelia and no diffusible pigments on most media tested. The strain grew in the presence of 0–12 % (w/v) NaCl (optimum, 2–4 %), at pH 9.0–11.0 (optimum, pH 9.0) and 10– 37 6C (optimum, 28 6C). The isolate contained meso-diaminopimelic acid, no diagnostic sugars and MK-9(H4) as the predominant menaquinone. The major phospholipids were phosphatidylglycerol, phosphatidylcholine and phosphatidylmethylethanolamine. The major fatty acids were iso-C16 : 0, anteiso-C17 : 0,C18 : 1v9c, iso-C15 : 0 and iso-C17 : 0. DNA–DNA relatedness was 37.6 % with Nocardiopsis lucentensis DSM 44048T, the nearest phylogenetic relative (97.93 % 16S rRNA gene sequence similarity). On the basis of the results of a polyphasic study, a novel species, Nocardiopsis fildesensis sp. nov., is proposed. The type strain is GW9-2T (5CGMCC 4.7023T5DSM 45699T5NRRL B-24873T). The genus Nocardiopsis was initially described by Meyer 28 uC and stored at 4 uC.

  • Evaluation of Antagonistic Activity of Actinobacteria in Saxicolous Lichens
    INTERNATIONAL JOURNAL OF AGRICULTURE & BIOLOGY ISSN Print: 1560–8530; ISSN Online: 1814–9596 16–339/2017/19–2–219–225 DOI: 10.17957/IJAB/15.0234 http://www.fspublishers.org Full Length Article Evaluation of Antagonistic Activity of Actinobacteria in Saxicolous Lichens Dongsheng Wang* and Haike Ren College of Life Science, Shanxi Normal University, Linfen, Shanxi 041000, China *For corresponding author: wangds@sxnu.edu.cn Abstract Actinobacteria are important producers of novel bioactive compounds. New sources need to be explored for isolating previously unknown bioactive compound-producing actinobacteria. We evaluated the potential of saxicolous lichens as a natural source of novel bioactive actinobacterial species. Saxicolous lichen samples were collected from three climatic belts at different elevations (1600–3400 m) on Qin Mountain, Shaanxi Province, China. Actinobacteria were cultivated, enumerated, and isolated using serial dilution and spread-plate techniques under normal nutrient and oligotrophic conditions. Antimicrobial activity of actinobacterial isolates was analyzed using an agar block method against fifteen typical bacterial and fungal species and plant pathogens. The dominant isolates and isolates with broad-spectrum antagonistic activity were identified by 16S rRNA-based sequence analysis. Results showed that colony counts, total number of species, and the number of bioactive species of actinobacteria in saxicolous lichens were higher in elevation <3000 m than in elevation >3000 m. The dominant isolates were classified into 42 species of 10 genera. Antagonistic activities were detected in approximately 66% of the actinobacteria isolates. Of these, 42 isolates (28%) showed broad-spectrum antagonistic activity against ≥5 microorganisms tested. In conclusion, the saxicolous lichen possesses a high diversity of actinobacteria and serves as a natural source of bioactive compound-producing actinobacteria.

The structures of these polymers or their combinations have been demonstrated to be indicative of each of seven Nocardiopsis species and two subspecies, verified by the DNA^DNA relatedness data, and to correlate well with the grouping of the organisms based on 16S rDNA sequences. As each of the intrageneric taxa discussed is definable by the composition of teichoic acids, the polymers are considered to be valuable taxonomic markers for the Nocardiopsis species and subspecies. The 13C NMR spectra of the polymers, data on the products of their chemical degradation, and distinguishing constituents of whole cell walls derived from teichoic acids are discussed, which are useful for identification of certain polymers and members of the genus Nocardiopsis at the species and subspecies level in microbiological practice.

  • The Genus Nocardiopsis Represents a Phylogenetically Coherent Taxon and a Distinct Actinomycete Lineage: Prodosal of Nocardiomaceae Fam
    INTERNATIONAL JOURNALOF SYSTEMATICBACTERIOLOGY, Oct. 1996, p. 1088-1092 Vol. 46, No. 4 0020-7713/96/$04.00+0 Copyright 0 1996, International Union of Microbiological Societies The Genus Nocardiopsis Represents a Phylogenetically Coherent Taxon and a Distinct Actinomycete Lineage: ProDosal of Nocardiomaceae fam. nov. FRED A. RAINEY,” NAOMI WARD-RAINEY, REINER M. KROPPENSTEDT, AND ERKO STACKEBRANDT DSMZ-German Collection of Microorganisms and Cell Cultures, Braunschweig, Germany The genus Nocardiopsis was shown to be phylogenetically coherent and to represent a distinct lineage within the radiation of the order Actinomycetales. The closest relatives of the genus Nocardiopsis are members of the genera Actinomadura, Thermomonospora,Streptosporangium, and Microtetraspora. The intrageneric structure of the genus Nucardiupsis is shown to consist of a highly related species group containing Nucardiupsis dassonvillei, Nocardiopsis alborubida, and Nocardiopsis antarctica and a second group of less highly related species compris- ing Nocardiopsis alba subsp. alba, Nocardiopsis alba subsp. prasina, and Nocardiopsis listeri. Nocardiopsis lucen- tensis occupies a position intermediate between the two species groups. The results of a 16s ribosomal DNA sequence analysis are generally consistent with the available chemotaxonomic, phenotypic, and DNA-DNA hybridization data. The phylogenetic position and the morpho- and chemotaxonomic properties of Nocardiopsis species support the creation of a family for the genus Nocardiopsis, Nocardiopsaceae fam. nov. Meyer described the genus Nocardiopsis for the species Ac- present. Diagnostic for all members of the genus Nocardiopsis tinomadura dassonvillei in 1976 on the basis of the morpholog- is the combination of 15 to 20% anteiso-C,,:, (14-methylhexa- ical characteristics and cell wall type of this organism (21).

The major fatty acids were T ignated B32 , was isolated from a Saharan soil sample found to be iso-C16:0 and anteiso-C15:0. The diagnostic collected from Adrar province (South of Algeria), and phospholipids detected were phosphatidylcholine, then investigated using a polyphasic taxonomic phosphatidylmethylethanolamine, diphosphatidyl- approach. The strain was observed to produce short glycerol, phosphatidylglycerol and phosphatidyletha- chains of spores on the dichotomous branched aerial nolamine. The chemotaxonomic properties of strain mycelium and formed a fragmented substrate myce- B32T are consistent with those shared by members of lium. The optimum NaCl concentration for growth the genus Nocardiopsis. 16S rRNA gene sequence was found to be 0–5 % (w/v) and the optimum growth analysis indicated that strain B32T is most closely temperature and pH were found to be 25–35 °C and related to Nocardiopsis alba DSM 43377T (98.7 %), 7.0–10.0 °C, respectively.
