  • Verrucosispora sonchi sp nov a novel endophytic actinobacterium isolated from the leaves of common sowthistle sonchus oleraceus l
    International Journal of Systematic and Evolutionary Microbiology, 2016
    Co-Authors: Shanshan Zhao, Wensheng Xiang, Ying Huang, Xiangjing Wang
    Abstract:

    A novel actinobacterium, designated strain NEAU-QY3T, was isolated from the leaves of Sonchus oleraceus L. and examined using a polyphasic taxonomic approach. The organism formed single spores with smooth surface on substrate mycelia. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain had a close association with the genus Verrucosispora and shared the highest sequence similarity with Verrucosispora qiuiae RtIII47T (99.17 %), an association that was supported by a bootstrap value of 94 % in the neighbour-joining tree and also recovered with the maximum-likelihood algorithm. The strain also showed high 16S rRNA gene sequence similarities to Xiangella phaseoli NEAU-J5T (98.78 %), Jishengella endophytica 202201T (98.51 %), Micromonospora eburnea LK2-10T (98.28 %), Verrucosispora lutea YIM 013T (98.23 %) and Salinispora pacifica CNR-114T (98.23 %). Furthermore, phylogenetic analysis based on the gyrB gene sequences supported the conclusion that strain NEAU-QY3T should be assigned to the genus Verrucosispora . However, the DNA–DNA hybridization relatedness values between strain NEAU-QY3T and V. qiuiae RtIII47T and V. lutea YIM 013T were below 70 %. With reference to phenotypic characteristics, phylogenetic data and DNA–DNA hybridization results, strain NEAU-QY3T was readily distinguished from its most closely related strains and classified as a new species, for which the name Verrucosispora sonchi sp. nov. is proposed. The type strain is NEAU-QY3T (=CGMCC 4.7312T=DSM 101530T).

  • Description of Verrucosispora qiuiae sp. nov., isolated from mangrove swamp sediment, and emended description of the genus Verrucosispora
    International Journal of Systematic and Evolutionary Microbiology, 2012
    Co-Authors: Limin Zhang, Jisheng Ruan, Ying Huang
    Abstract:

    A Micromonospora -like strain, RtIII47T, was isolated from a mangrove swamp in Sanya, Hainan Province, China. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain had a close association with the genus Verrucosispora and shared the highest sequence similarity with Verrucosispora lutea YIM 013T (98.0 %). The strain also showed high 16S rRNA gene sequence similarities to Micromonospora olivasterospora DSM 43868T (97.9 %), Plantactinospora mayteni YIM 61359T (97.9 %), Salinispora tropica CNB-440T (97.8 %), Micromonospora peucetia DSM 43363T (97.7 %), Micromonospora auratinigra TT1-11T (97.7 %), Verrucosispora sediminis CGMCC 4.3550T (97.6 %) and Salinispora arenicola CNH-643T (97.5 %). Phylogenetic analysis based on the gyrB gene sequence supported the conclusion that strain RtIII47T should be assigned to the genus Verrucosispora . DNA–DNA relatedness between strain RtIII47T and the most closely related type strain, V. lutea YIM 013T, was less than 40 %. Chemotaxonomic results confirmed the taxonomic position of the isolate in the genus Verrucosispora , and revealed differences at the species level in polar lipids, whole-cell sugars and DNA G+C content. A combination of physiological and biochemical tests also distinguished this strain from other Verrucosispora species. Based on genotypic and phenotypic observations, strain RtIII47T ( = CGMCC 4.5826T  = NBRC 106684T) is proposed as the type strain of a novel species, Verrucosispora qiuiae sp. nov. An emended description of the genus Verrucosispora is also provided.

  • Diversity and Biosynthetic Potential of Culturable Actinomycetes Associated with Marine Sponges in the China Seas
    International journal of molecular sciences, 2012
    Co-Authors: Jisheng Ruan, Ying Huang
    Abstract:

    The diversity and secondary metabolite potential of culturable actinomycetes associated with eight different marine sponges collected from the South China Sea and the Yellow sea were investigated. A total of 327 strains were isolated and 108 representative isolates were selected for phylogenetic analysis. Ten families and 13 genera of Actinomycetales were detected, among which five genera represent first records isolated from marine sponges. Oligotrophic medium M5 (water agar) proved to be efficient for selective isolation, and “Micromonospora–Streptomyces” was proposed as the major distribution group of sponge-associated actinomycetes from the China Seas. Ten isolates are likely to represent novel species. Sponge Hymeniacidon perleve was found to contain the highest genus diversity (seven genera) of actinomycetes. Housekeeping gene phylogenetic analyses of the isolates indicated one ubiquitous Micromonospora species, one unique Streptomyces species and one unique Verrucosispora phylogroup. Of the isolates, 27.5% displayed antimicrobial activity, and 91% contained polyketide synthase and/or nonribosomal peptide synthetase genes, indicating that these isolates had a high potential to produce secondary metabolites. The isolates from sponge Axinella sp. contained the highest presence of both antimicrobial activity and NRPS genes, while those from isolation medium DNBA showed the highest presence of antimicrobial activity and PKS I genes.

  • A novel taxonomic marker that discriminates between morphologically complex actinomycetes
    Open biology, 2013
    Co-Authors: Geneviève Girard, Michael Goodfellow, Bjørn A. Traag, Vartul Sangal, Nadine Mascini, Paul A. Hoskisson, Gilles P. Van Wezel
    Abstract:

    In the era when large whole genome bacterial datasets are generated routinely, rapid and accurate molecular systematics is becoming increasingly important. However, 16S ribosomal RNA sequencing does not always offer sufficient resolution to discriminate between closely related genera. The SsgA-like proteins are developmental regulatory proteins in sporulating actinomycetes, whereby SsgB actively recruits FtsZ during sporulation-specific cell division. Here, we present a novel method to classify actinomycetes, based on the extraordinary way the SsgA and SsgB proteins are conserved. The almost complete conservation of the SsgB amino acid (aa) sequence between members of the same genus and its high divergence between even closely related genera provides high-quality data for the classification of morphologically complex actinomycetes. Our analysis validates Kitasatospora as a sister genus to Streptomyces in the family Streptomycetaceae and suggests that Micromonospora, Salinispora and Verrucosispora may represent different clades of the same genus. It is also apparent that the aa sequence of SsgA is an accurate determinant for the ability of streptomycetes to produce submerged spores, dividing the phylogenetic tree of streptomycetes into liquid-culture sporulation and no liquid-culture sporulation branches. A new phylogenetic tree of industrially relevant actinomycetes is presented and compared with that based on 16S rRNA sequences.

  • Verrucosispora fiedleri sp. nov., an actinomycete isolated from a fjord sediment which synthesizes proximicins
    Antonie van Leeuwenhoek, 2012
    Co-Authors: Michael Goodfellow, James E M Stach, Roselyn Brown, Amanda Jones, Tiago Domingues Zucchi, Lina Ahmed, Wasu Pathom-aree, Alan T. Bull, Lixin Zhang, Jian Wang
    Abstract:

    A novel filamentous actinobacterial organism, designated strain MG-37T, was isolated from a Norwegian fjord sediment and examined using a polyphasic taxonomic approach. The organism was determined to have chemotaxonomic and morphological properties consistent with its classification in the genus Verrucosispora and formed a distinct phyletic line in the Verrucosispora 16S rRNA gene tree. It was most closely related to Verrucosispora maris DSM 45365T (99.5 % 16S rRNA gene similarity) and Verrucosispora gifhornensis DSM 44337T (99.4 % 16S rRNA gene similarity) but was distinguished from these strains based on low levels of DNA:DNA relatedness (~56 and ~50 %, respectively). It was readily delineated from all of the type strains of Verrucosispora species based on a combination of phenotypic properties. Isolate MG-37T (=NCIMB 14794T = NRRL-B-24892T) should therefore be classified as the type strain of a novel species of Verrucosispora for which the name Verrucosispora fiedleri is proposed.

  • Verrucosispora wenchangensis sp. nov., isolated from mangrove soil
    Antonie van Leeuwenhoek, 2012
    Co-Authors: Qing-yi Xie, Michael Goodfellow, Roselyn Brown, Hai-peng Lin, Zixin Deng, Kui Hong
    Abstract:

    An actinomycete strain 234402T was isolated from a mangrove soil sample collected in Wenchang, China. Phylogenetic analysis of the 16S rRNA gene sequence of strain 234402T indicated that the highest similarity was to Verrucosispora sediminis MS426T (99.25%). The cell wall contained meso-diaminopimelic acid. The major menaquinones were MK-9(H4) and MK-9(H6), with MK-9(H8) as minor components. The characteristic whole-cell sugars were xylose, mannose and glucose. The phospholipid profile was found to comprise phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside and an unknown phospholipid. The DNA G+C content was 69.2 mol%. The results of physiological and biochemical tests and low DNA–DNA relatedness demonstrated strain 234402T could be readily distinguished from the closely related Verrucosispora species. On the basis of these phenotypic and genotypic data, strain 234402T represents a novel species of the genus Verrucosispora, for which the name Verrucosispora wenchangensis sp. nov. is proposed. The type strain is 234402T (=CCTCC AA 2011018T=DSM 45674T).

  • Verrucosispora maris sp nov a novel deep sea actinomycete isolated from a marine sediment which produces abyssomicins
    Antonie Van Leeuwenhoek International Journal of General and Molecular Microbiology, 2012
    Co-Authors: Michael Goodfellow, James E M Stach, Roselyn Brown, Avinash Naga Venkata Bonda, Amanda Jones, Joanne Mexson, Hanspeter Fiedler, Tiago Domingues Zucchi
    Abstract:

    Verrucosispora isolate AB-18-032T, the abyssomicin- and proximicin-producing actinomycete, has chemotaxonomic and morphological properties consistent with its classification in the genus Verrucosispora. The organism formed a distinct phyletic line in the Verrucosispora 16S rRNA gene tree sharing similarities of 99.7%, 98.7% and 98.9% with Verrucosispora gifhornensis DSM 44337T, Verrucosispora lutea YIM 013T and Verrucosispora sediminis MS 426T, respectively. It was readily distinguished from the two latter species using a range of phenotypic features and from V. gifhornensis DSM 44337T, its nearest phylogenetic neighbor, by a DNA G+C content of 65.5 mol% obtained by thermal denaturation and fluorometry and DNA:DNA relatedness values of 64.0% and 65.0% using renaturation and fluorometric methods, respectively. It is apparent from the combined genotypic and phenotypic data that strain AB-18-032T should be classified in the genus Verrucosispora as a new species. The name Verrucosispora maris sp. nov. is proposed for this taxon with isolate AB-18-032T (= DSM 45365T = NRRL B-24793T) as the type strain.
