“…The family Nocardiopsaceae was proposed by Rainey and colleagues [1] and belongs to the order Streptosporangiales [2] and the class Actinomycetia [3]. Currently, it comprises 12 genera (https://lpsn.dsmz.de/family/nocardiopsaceae), including Nocardiopsis as type genus [4], Actinorugispora [5], Allosalinactinospora [6], Haloactinospora [7], Lipingzhangella [8], Marinactinospora [9], Marinitenerispora [10], Murinocardiopsis [11], Salinactinospora [12], Spinactinospora [13], Streptomonospora [14] and Thermobifida [15]. Members of the family Nocardiopsaceae are Gram-stain-positive, aerobic and non-acid-fast bacteria.…”

An alkaliphilic actinobacterium, designated VN6-2T, was isolated from marine sediment collected from Valparaíso Bay, Chile. Strain VN6-2T formed yellowish-white branched substrate mycelium without fragmentation. Aerial mycelium was well developed, forming wavy or spiral spore chains. Strain VN6-2T exhibited a 16S rRNA gene sequence similarity of 93.9 % to Salinactinospora qingdaonensis CXB832T, 93.7 % to Murinocardiopsis flavida 14-Be-013T, and 93.7 % to Lipingzhangella halophila 14-Be-013T. Genome sequencing revealed a genome size of 5.9 Mb and an in silico G+C content of 69.3 mol%. Both of the phylogenetic analyses based on 16S rRNA gene sequences and the up-to-date bacterial core gene sequences revealed that strain VN6-2T formed a distinct monophyletic clade within the family Nocardiopsaceae . Chemotaxonomic assessment of strain VN6-2T showed that the major fatty acids were iso-C16 : 0, anteiso-C17 : 0 and 10-methyl-C18 : 0, and the predominant respiratory quinones were MK-9, MK-9(H2) and MK-9(H4). Whole-cell hydrolysates contained meso-diaminopimelic acid as the cell-wall diamino acid, and ribose and xylose as the diagnostic sugars. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, aminophospholipids, glycolipid and phospholipid. Based on the results of this polyphasic study, a novel genus, Spiractinospora gen. nov., is proposed within the family Nocardiopsaceae and the type species Spiractinospora alimapuensis gen. nov., sp. nov. The type strain is VN6-2T (CECT 30026T, CCUG 66258T). On the basis of the phylogenetic results herein, we also propose that Nocardiopsis arvandica and Nocardiopsis litoralis are later heterotypic synonyms of Nocardiopsis sinuspersici and Nocardiopsis kunsanensis , respectively, for which emended descriptions are given.

The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. Note that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes.

Ma.rin.ac.ti.no.spo'ra. L. masc. adj. marinus of the sea; Gr. fem. n. actis actinos a ray; Gr. fem. n. spora a seed; N.L. fem. n. Marinactinospora marine and spored ray, referring to marine spore‐forming actinomycete. Actinobacteria / Actinobacteria / Streptosporangiales / Nocardiopsaceae / Marinactinospora The genus Marinactinospora is classified with the family Nocardiopsaceae , order Streptosporangiales , in the class Actinobacteria . Phylogenetically, strains in this genus share 16S rRNA gene sequence similarities of less than 97.3% with other members of the family Nocardiopsaceae and form a distinct clade in the Neighbor‐joining phylogenetic tree. Strains form well‐branched but non‐fragmented substrate mycelia and aerial mycelia which differentiate into long spore chains. Cells are nonmotile and Gram‐stain‐positive. Strains could grow well over a wide range of physiological conditions: 10–55°C, 0–7% (w/v) NaCl, and pH 6.0–10.0. They are aerobic, chemoorganotrophic, and can grow in defined media on a range of substrates. Major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylinositol mannosides. Currently, the genus consists of two species: Marinactinospora thermotolerans (the type species of the genus) and Marinactinospora endophytica , from the deep‐sea sediment and traditional Chinese medicinal plant ( Salsola ferganica Drob), respectively. DNA G + C content (mol%) : 70.5–72.0 (HPLC). Type species : Marinactinospora thermotolerans Tian et al. 2009 VP .
