Verrucosispora maris sp. nov., a novel deep-sea actinomycete isolated from a marine sediment which produces abyssomicins

Abstract

Verrucosispora isolate AB-18-032(T), 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 44337(T), Verrucosispora lutea YIM 013(T) and Verrucosispora sediminis MS 426(T), respectively. It was readily distinguished from the two latter species using a range of phenotypic features and from V. gifhornensis DSM 44337(T), 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-18-032(T) 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-18-032(T) (= DSM 45365(T) = NRRL B-24793(T)) as the type strain.

Taxonomic Diversity and Antimicrobial Activities of Actinomycetes from Manure Composts

“…These evidence implied that this strain is likely an inhabitant of specifically manure-based compost as there is still no study found to suggest otherwise. In the present study also, one isolate (C2A1) recovered from cow manure compost showed closest similarity (99.1%) to Verrucosispora maris which was initially reported from deep-sea sediments (Goodfellow et al, 2012). It has been debated for many years without consensus whether marine actinomycetes are actually native marine population or simply a wash off terrestrial microorganisms (Jensen et al, 1991;Takizawa et al, 1993).…”

Marine Rare Actinobacteria: Isolation, Characterization, and Strategies for Harnessing Bioactive Compounds

“…These marine actinobacteria with potential of producing bioactive compounds have attracted major attention to search for unique compounds with pharmaceutical and biotechnological applications (Bull and Stach, 2007; Subramani and Aalbersberg, 2013; Azman et al, 2015). Recently, there are reports on the discovery of rare actinobacteria from wide range of terrestrial and aquatic locations, including deep seas (Goodfellow et al, 2012). Reports on the analysis of geographical origins of the marine rare actinobacteria, with special focus on the isolation of specific compounds, and precise bioactivities are predominant indications of increasing global interest on the natural compounds from marine rare actinobacteria (Blunt et al, 2007).…”

Genus Diversity of Actinomycetes in Cibinong Science Center, West Java, Indonesia

“…The position of isolates of the family Kineosporiaceae selected in this study represented a line of descent distinct from previously described species of this family and further information are needed to describe the isolates (Fig 1). There was only 1 species, Verrucosispora gifhornensis under the genus Verrucosispora reported previously (Rheims et al 1998), however 5 other species were reported recently (Liao et al 2009;Dai et al 2010;Goodfellow et al 2012;Xi et al 2012;Xie et al 2012). Isolate from CSC, Verrucosispora SP ID06-A0238 is separated from those known species (Fig 2), Volume 6, 2012 Microbiol Indones 169…”
