“…The fatty acid profiles of strain TS-T11 T and the three reference type strains are shown in . The cellular fatty acid profiles obtained in this study for the reference type strains were similar to those originally reported (Jean et al , 2006; Park et al , 2010; Yoon et al , 2007) and reported in other publications (Chen et al , 2012; Song et al , 2013; Taborda et al , 2009) in terms of major fatty acids. All these strains contained iso-C 15 : 0 , iso-C 17 : 0 and iso-C 17 : 1 ω9 c as major fatty acids, although in different proportions, which might be due to the different culture conditions.…”

“…Similar polar lipid profiles were shown with the three reference type strains. The polar lipid profiles obtained in this study for I. salinarum DSM 21900 T and I. taiwanensis CGMCC 1.12292 T were similar to those described previously (Chen et al , 2012). All of strain TS-T11 T and the three reference type strains had PE, PG, DPG and five uncharacterized phospholipids (PL1–PL5).…”

A Gram-stain-negative bacterium, strain TS-T11 T , was isolated from Tuosu lake, a saline lake (salinity 5.4 %, w/v) in the Qaidam basin, Qinghai province, China. Its taxonomic position was determined by using a polyphasic approach. Cells of strain TS-T11T were non-spore-forming rods, 0.6-0.8 mm wide and 0.8-2.2 mm long, and motile by means of a single polar flagellum. Strain TS-T11 T was strictly heterotrophic and aerobic. Cells were positive for catalase and oxidase. Growth was observed in the presence of 0.5-11.0 % (w/v) NaCl (optimum 4.0-6.0 %), at 4-40 6C (optimum 30-35 6C) and at pH 6.0-10.5 (optimum pH 7.5-8.5). Strain TS-T11T contained iso-C 15 : 0 , iso-C 17 : 0 and iso-C 17 : 1 v9c as the predominant fatty acids (.10 %). The major respiratory quinone was Q-8. The polar lipids consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and nine uncharacterized phospholipids. The G+C content of genomic DNA was 46.8 mol% (T m ). Phylogenetic trees based on 16S rRNA gene sequences showed that strain TS-T11 T was associated with the genus Idiomarina, and showed highest 16S rRNA gene sequence similarity to Idiomarina aestuarii KYW314 T (97.4 %) and Idiomarina salinarum ISL-52 T (97.4 %). DNA-DNA relatedness of strain TS-T11 T to I. aestuarii JCM 16344 T and I. salinarum DSM 21900 T was 22.2±2.4 and 11.5±1.6 %, respectively. Based on the data presented above, it was concluded that strain TS-T11

“…The description is identical to that given for Idiomarina homiensis by Kwon et al (2006) . Additional characteristics are as follows: the polar lipids comprise PE, PG, DPG, phosphatidylserine (PS), an uncharacterized aminolipid (AL1) and eight uncharacterized PLs (PL1-PL8) ( Chen et al, 2012 ). The type strain is PO-M2 T ( = KACC 11514 T = DSM 17923 T ), which was isolated from seashore sand in Pohang, Korea.…”

Genome-Based Analysis Reveals the Taxonomy and Diversity of the Family Idiomarinaceae

Idiomarinaceae is a family of Gram-stain negative, mesophilic euryhalophiles. To provide a robust framework for the evolutionary and taxonomic relationships of bacteria of this family, we compared herein the genomes of 36 type strains and 43 non-type strains using 16S rRNA gene sequences, core genome based 78 single-copy orthologous proteins, digital DNA-DNA hybridization and average nucleotide identity (ANI) estimation. The 79 bacteria of this family were consistently divided into taxon I, taxon II, and taxon III corresponding to the three genera Idiomarina, Pseudidiomarina, and Aliidiomarina, which contained 13 putative new genospecies in addition to 35 well-defined species represented by each type strain. Furthermore, genetic diversity of this family was evident at the genus- and species levels, and exceeded that which is defined currently by the named species. In view of multiple genotypic characteristics clearly distinct from the other two genera, we propose reinstating the genus Pseudidiomarina as a monophyletic taxon. Taken together, this is the first genome-based study of the taxonomy and diversity of bacteria within the family Idiomarinaceae, and will contribute to further insights into microbial evolution and adaptation to saline environments.

“…is not a typical representative of the marine waters around Helgoland. It has been isolated from various marine environments such as deep-sea waters, hydrothermal vents, sediments, and reef building corals (e.g., Ivanova et al, 2000 ; Donachie et al, 2003 ; Chen et al, 2012 ; Zhang et al, 2012 ), but also from estuarine environments like Baltic Sea surface water (Brettar et al, 2003 ). The increased occurrence of these two OTUs at Helgoland Roads during the first half of the sampling period (group A), leads to the hypothesis that OTUs that are commonly associated with coastal marine environments have been passively transported to Helgoland Roads with the above mentioned coastal water inflow.…”

Short-Term Dynamics of North Sea Bacterioplankton-Dissolved Organic Matter Coherence on Molecular Level

Remineralization and transformation of dissolved organic matter (DOM) by marine microbes shape the DOM composition and thus, have large impact on global carbon and nutrient cycling. However, information on bacterioplankton-DOM interactions on a molecular level is limited. We examined the variation of bacterial community composition (BCC) at Helgoland Roads (North Sea) in relation to variation of molecular DOM composition and various environmental parameters on short-time scales. Surface water samples were taken daily over a period of 20 days. Bacterial community and molecular DOM composition were assessed via 16S rRNA gene tag sequencing and ultrahigh resolution Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), respectively. Environmental conditions were driven by a coastal water influx during the first half of the sampling period and the onset of a summer phytoplankton bloom toward the end of the sampling period. These phenomena led to a distinct grouping of bacterial communities and DOM composition which was particularly influenced by total dissolved nitrogen (TDN) concentration, temperature, and salinity, as revealed by distance-based linear regression analyses. Bacterioplankton-DOM interaction was demonstrated in strong correlations between specific bacterial taxa and particular DOM molecules, thus, suggesting potential specialization on particular substrates. We propose that a combination of high resolution techniques, as used in this study, may provide substantial information on substrate generalists and specialists and thus, contribute to prediction of BCC variation.
