“…The predominant ubiquinone of strain JJ-M1 T was ubiquinone-9 (Q-9), which is in accordance with all other members of the genus Halomonas (Franzmann & Tindall, 1990;Arahal & Ventosa, 2006). Phosphatidylglycerol, phosphatidylethanolamine, phosphoglycolipid (PGL) and diphosphatidylglycerol (DPG) were identified as the major polar lipids and four unidentified phospholipids were also detected as minor polar lipids (Fig.…”

“…At the time of writing, the family Halomonadaceae belonging to the class Gammaproteobacteria consists of nine halophilic genera with validly published names (Aidingimonas, Chromohalobacter, Cobetia, Halomonas, Halotalea, Kushneria, Modicisalibacter, Salinicola and Larsenimonas) (Vreeland et al, 1980;Ventosa et al, 1989;Mellado et al, 1995;Arahal et al, 2002;Arahal & Ventosa, 2006;Gam et al, 2007;Ntougias et al, 2007;Sánchez-Porro et al, 2009;Wang et al, 2009;Leó n et al, 2015) that are capable of growth in saline environments with 15 % (w/v) salt concentrations plus two nonhalophilic genera (Carnimonas and Zymobacter) (Okamoto et al, 1993;Garriga et al, 1998). Among the genera, the genus Halomonas including Gram-stain-negative, moderately halophilic, aerobic or facultatively aerobic rod-shaped bacteria is the largest genus, which includes 90 species with validly published names that have been isolated from diverse saline environments such as solar salterns, salt lakes, fermented seafood, sea squirts, sea ice, hydrothermal vents and saline-alkali soil (Vreeland et al, 1980;Ventosa et al, 1998;Romanenko et al, 2002;Yoon et al, 2002;Kaye et al, 2004;Lim et al, 2004;Arenas et al, 2009;Kim et al, 2010;Guan et al, 2010;Guzmán et al, 2010;Jeong et al, 2013;Miao et al, 2014).…”

f Halomonas stevensii is a Gram-negative, moderately halophilic bacterium causing environmental contamination and infections in a dialysis center. Here we present the 3.7-Mb draft genome sequence of the type strain (S18214 T ) of H. stevensii, which will give insight into the pathogenic potential of H. stevensii. The genus Halomonas accommodates moderately halophilic/halotolerant microorganisms that typically occur in saline or hypersaline environments. Therefore, many studies on these bacteria have focused on their biotechnological potential and applications (1). However, during the last few decades, several bacterial strains belonging to two different Halomonas species, Halomonas venusta and "Halomonas phocaeensis," have been reported to be a cause of human infections (3,8). Very recently, a number of Halomonas strains were isolated from the blood of two renal care patients that was obtained during dialysis and from the dialysis machines and other environmental sources in a renal care center (6), highlighting the nosocomial infection and pathogenic potential of the genus Halomonas. Subsequently, the patient isolates, strains S18214T and T49407, have been classified as the novel species Halomonas stevensii (5).The genome sequence of H. stevensii S18214 T was determined using the GS FLX Titanium system (Roche Diagnostics, Branford, CT) with an 8-kb-span paired-end library (218,050 reads, ϳ43.0 Mb) and Illumina GA IIx (San Diego, CA) with 100 bp paired-end information (14,290,561 reads, ϳ1,529.1 Mb). All reads were assembled into 53 contigs (N 50 , 131,909 bp; maximum contig size, 302,635 bp) using GS Assembler 2.6 (Roche Diagnostics, Branford, CT) and CLC Genomics Workbench 4.9 (CLC bio, Denmark); total coverage over the whole genome reached ϳ426-fold. The resultant genome sequence wasuploadedintotheRASTserver(2)topredicttheopenreadingframes (ORFs), tRNAs, and rRNAs. The predicted ORFs were annotated by searching against the COG (7) and SEED (4) databases.The draft genome was 3,693,745 bp in length, with a GϩC content of 60.3 mol%. Among 2,286 predicted protein-coding sequences, 1,287 (56.3%) ORFs were assigned to COGs. The genome also contained 56 tRNA genes and 4 rRNA operons.Putative genomic islands (GIs) were identified based on the algorithm developed by Yoon et al. (9). The length proportion of the GIs to the genome was 24.0%, a value that is much higher than the average proportion of 10.1% for 148 prokaryotic genomes (9). Subsequent detection of potential pathogenicity islands (PAIs) was performed using the PAI Finder (10), a web-based search tool of the pathogenicity island database (PAIDB), and revealed no PAI-like region. However, H. stevensii S18214 T encoded some putative virulence factors, such as the RTX protein, the type I secretion system, the iron uptake system, adhesion-type proteins, stress proteins, flagella, fimbriae, and the resistance-nodulation-cell division (RND) efflux system, which might promote infections in immunocompromised people. In conclusion, this is the first report of the draf...

“…The family Halomonadaceae includes an heterogeneous group of aerobic, heterotrophic, Gram-negative rods with oxidative metabolism (Franzmann et al, 1988;Arahal & Ventosa, 2005). The species of this family are phylogenetically members of the class Gammaproteobacteria and, at the time of writing, are included within nine genera: Halomonas (type genus of the family) (Vreeland et al, 1980), Carnimonas (Garriga et al, 1998), Chromohalobacter (Ventosa et al, 1989), Cobetia (Arahal et al, 2002a), Halotalea , Kushneria (Sánchez-Porro et al, 2009), Modicisalibacter (Ben Ali Gam et al, 2007), Salinicola (Anan'ina et al, 2007) and Zymobacter (Okamoto et al, 1993).…”

“…H. salaria DSM 18044 T and S. socius DSM 19940 T also contained Q9 as the major respiratory quinone (Anan'ina et al, 2007;Kim et al, 2007). This ubiquinone is typically found in members of the family Halomonadaceae (Arahal & Ventosa, 2005;Vreeland, 2005;Arahal et al, 2007), although the presence of minor amounts of Q8 and Q10 has been reported for species of the genus Kushneria Fatty acids were analysed by GC (Kämpfer & Kroppenstedt, 1996;Miller, 1982) at the Belgian Co-ordinated Collections of Micro-organisms, Laboratory of Microbiology of Gent (BCCM/LMG), Gent, Belgium. Cells were cultured on TSA medium (BBL) supplemented with 10 % NaCl at pH 7.0, 28 u C for 48 h. The predominant fatty acids of strains S. socius DSM 19940 T , H. salaria DSM 18044 T and C. salarius Unless otherwise indicated, data are from this study.…”

We have carried out a polyphasic taxonomic characterization of the type strains of the species with the recently validated name Salinicola socius, together with two species that were phylogenetically closely related, Halomonas salaria and Chromohalobacter salarius. 16S rRNA gene sequence analyses showed that they constituted a coherent cluster, with sequence similarities between 98.7 and 97.7 %. We have determined the almost complete 23S rRNA gene sequences of these three type strains, and the percentage of similarity between them was 99.2–97.6 %. Phylogenetic trees based on the 16S rRNA and 23S rRNA gene sequences, obtained by using three different algorithms, were consistent and showed that these three species constituted a cluster separated from the other species of the genera of the family Halomonadaceae, supporting their placement in a single genus. All three species have ubiquinone 9 as the major respiratory quinone, and showed similar fatty acid and polar lipid profiles. The level of DNA–DNA hybridization between Salinicola socius DSM 19940T, Halomonas salaria DSM 18044T and Chromohalobacter salarius CECT 5903T was 41–21 %, indicating that they are different species of the genus Salinicola. A comparative phenotypic study of these strains following the proposed minimal standards for describing new taxa of the family Halomonadaceae has been carried out. The phenotypic data are consistent with the placement of these three species in a single genus and support their differentiation at the species level. On the basis of these data we have emended the description of the species Salinicola socius and we propose to transfer the species Halomonas salaria and Chromohalobacter salarius to the genus Salinicola, as Salinicola salarius comb. nov. (type strain M27T =KCTC 12664T =DSM 18044T) and Salinicola halophilus nom. nov. (type strain CG4.1T =CECT 5903T =LMG 23626T), respectively.
