Abstract
A Gram-reaction-negative, aerobic, motile, rod-shaped bacterium, designated GH3-8T, was isolated from rhizosphere mudflats of halophytes on the seashore of Gangwha Island, Republic of Korea. Growth was observed at pH 4-10 (optimum, pH 7-8), at 4-40 °C (optimum, 37 °C) and in the presence of 0.5-20 % (w/v) NaCl (optimum, 4 %). The predominant respiratory quinone was Q-9. The major fatty acids were C18 : 1 ω7c, C16 : 0, summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) and C12 : 0 3OH. The polar lipids contained phosphatidylethanolamine, phosphatidylglycerol, an unidentified phosphoglycolipid, an unidentified phosphoglycoaminolipid, an unidentified glycoaminolipid, two unidentified phospholipids and two unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences exhibited that the isolate belonged to the family Halomonadaceae, with the most closely related species, Larsenimonas suaedae (98.1 % sequence similarity) and Larsenimonas salina (97.9 %). Sequence similarity values between the isolate and other representatives of the family Halomonadaceae were all below 95.3 %. The values of average nucleotide identity between strain GH3-8T and members of the genus Larsenimonas were 73.42 % with L. salina CCM 8464T and 72.38 % with L. suaedae DSM 22428T. Strain GH3-8T showed digital DNA-DNA hybridization values of 18.5-18.6 % with members of the genus Larsenimonas. Based on phenotypic and chemotaxonomic distinctiveness together with low overall genomic relatedness indices and phylogenetic data, the isolate is considered to represent a new species of the genus Larsenimonas, for which the name Larsenimonas rhizosphaerae sp. nov. is proposed, with the type strain GH3-8T (=KCTC 62127T=NBRC 113214T).

Abstract
There are few biological indicators for freshwater systems subjected to high chloride levels. Freshwater systems receive many forms of chloride such as road salts (e.g., NaCl, CaCl2, MgCl2), fertilizers (e.g., KCl), and year-round water softener pollution. The goal our study was to investigate Halomonadaceae populations as prospective biological indicators of chloride-impacted freshwaters. The bacterial family Halomonadaceae are halophiles that generally require the presence of salt to survive, which make them an attractive candidate in determining chloride impaired areas. Field sediment surveys assessed how salt tolerant and halophilic bacteria abundance corresponded to chloride and conductivity measurements. Colony forming unit (CFU) counts on modified M9 6% NaCl plates (w/v) at urbanized sites compared to the rural sites had highest counts during winter and spring when chloride concentrations were also highest. Select isolates identified as Halomonadaceae through 16S rRNA sequencing were kept as active cultures to determine the NaCl concentration and temperature preference that resulted in the isolates optimal growth. Isolates tested under 5 °C (cold) grew optimally in 2 % NaCl (w/v), whereas under 18 °C (warm), isolates showed optimal growth at 6 % NaCl. The majority of isolates had maximum growth in the warmer temperature, however, select isolates grew better in the cold temperature. Culture-independent methods were used and identified Halomonadaceae were widespread and permeant members of the microbial community in a Lake Michigan drainage basin. Quantitative polymerase chain reaction (qPCR) targeting Halomonadaceae genera demonstrated that abundance varied by site, but overall were present throughout the year. However, community sequencing revealed there were a large relative proportion of specific Halomonadaceae populations present in winter versus summer. Methods targeting salt tolerant bacteria and specific members of Halomonadaceae appears to be a promising approach to assess chloride-impacted areas to better understand the long-term ecological impacts as we continue to salinize freshwater resources.

Abstract
A moderately halophilic, Gram-stain-negative, aerobic bacterium, strain D1-1T, belonging to the genus Halomonas, was isolated from soil sampled at Pentha beach, Odisha, India. Phylogenetic trees reconstructed based on 16S rRNA genes and multilocus sequence analysis of gyrB and rpoD genes revealed that strain D1-1T belonged to the genus Halomonas and was most closely related to Halomonas alimentaria YKJ-16T (98.1 %) followed by Halomonas ventosae Al12T (97.5 %), Halomonas sediminicola CPS11T (97.5 %), Halomonas fontilapidosi 5CRT (97.4 %) and Halomonas halodenitrificans DSM 735T (97.2 %) on the basis of 16S rRNA gene sequence similarity. Sequence identities with other species within the genus were lower than 97.0 %. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values of 22.4-30 % and 79.5-85.4 % with close relatives of H. halodenitrificans DSM 735T, H. alimentaria YKJ-16T, H. ventosae Al12T and H. fontilapidosi 5CRT were lower than the threshold recommended for species delineation (70 % and 95-96 % for dDDH and ANI, respectively). Further, strain D1-1T formed yellow-coloured colonies; cells were rod-shaped, motile with optimum growth at 30 °C (range, 4-45 °C) and 2-8 % NaCl (w/v; grew up to 24 % NaCl). The major fatty acids were summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c), summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c) and C16 : 0 and the main respiratory quinone was ubiquinone Q-9 in line with description of the genus. Based on its chemotaxonomic and phylogenetic characteristics and genome uniqueness, strain D1-1T represents a novel species in the genus Halomonas, for which we propose the name Halomonas icarae sp. nov., within the family Halomonadaceae. The type strain is D1-1T (=JCM 33602T=KACC 21317T=NAIMCC-B-2254T).

Abstract
We carried out a polyphasic taxonomic study on a new halophilic strain designated 3(2)T, isolated from Meighan wetland, Iran. Cells of the novel strain were Gram-stain-negative, non-hemolytic, catalase- and oxidase-positive, rod-shaped, non-endospore-forming and motile. Cell growth occurred at 3-15 % NaCl (w/v; optimum, 5 %), pH 7.0-9.0 (optimum, pH 7.5-8.0) and 15-35 °C (optimum, 30 °C). 16S rRNA gene sequence comparisons confirmed the affiliation of strain 3(2)T to the class Gammaproteobacteria and the genus Halomonas with highest similarity to Halomonas daqiaonensis YCSA28T (98.4 %) and Halomonas ventosae Al12T (97.9 %). Experimental and in silico DNA-DNA hybridization values were 42.7 and 35.1% with H. daqiaonensis IBRC-M 10931T and 48 and 35.2% with H. ventosae IBRC-M 10566T, respectively, and indicated that they are different members of the same genus. The genome of the type strain was characterized by a size of 3.83 Mbp with 63 scaffolds and a G+C content of 64.8 mol%. Moreover, the average nucleotide identity values against H. ventosae Al12T and H. daqiaonensis YCSA28T were 88.8 and 88.5 %, respectively. The predominant respiratory quinone was Q-9 (92 %) with Q-8 (8 %) as a minor component. Major fatty acids were C16 : 0 cyclo, C19 : 0 ω8c, C16 : 1 ω7c and/or iso-C15:0 2-OH, C12 : 0 3-OH and C18 : 1 ω7c. The polar lipid profile of the strain contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphoaminoglycolipid and four unidentified phospholipids. According to our results, strain 3(2)T could be classified as a novel species in the genus Halomonas for which the name Halomonas lysinitropha sp. nov. is proposed. The type strain is 3(2)T (=IBRC M 10929T=LMG 29450T=CIP 111708T).

Abstract
A gram-stain-negative, aerobic, non-spore-forming, rod-shaped, non-motile bacterium strain R4HLG17T was isolated from Tamarix ramosissima roots growing in Kumtag desert. The strain grew at salinities of 0-16% (w/v) NaCl (optimum 5-6%), pH 5-9 (optimum 7) and at 16-45 °C. Based on 16S rRNA gene sequence similarity, strain R4HLG17T belonged to the family Halomonadaceae and was most closely related to Halomonas lutea DSM 23508T(95.1%), followed by Halotalea alkalilenta AW-7T(94.8%), Salinicola acroporae S4-41T(94.8%), Salinicola halophilus CG4.1T(94.6%), and Larsenimonas salina M1-18T(94.4%). Multilocus sequence analysis (MLSA) based on the partial sequences of 16S rRNA, atpA, gyrB, rpoD, and secA genes indicated that the strain R4HLG17T formed an independent and monophyletic branch related to other genera of Halomonadaceae, supporting its placement as a new genus in this family. The draft genome of strain R4HLG17T was 3.6 Mb with a total G + C content of 55.1%. The average nucleotide identity to Halomonas lutea DSM 23508T was 83.5%. Q-9 was detected as the major respiratory quinone and summed feature 8 (C18:1ω7c/C18:1ω6c), summed feature 3 (C16:1ω7c/C16:1ω6c), and C16:0 as predominant cellular fatty acids. On the basis of chemotaxonomic, phylogenetic, and phenotypic evidence, strain R4HLG17T is concluded to represent a novel species of a new genus within Halomonadaceae, for which the name Phytohalomonas tamaricis gen. nov., sp. nov., is proposed. The type strain is R4HLG17T (=ACCC 19929T=KCTC 52415T).

Abstract
Seven endophytic strains were isolated from the halophyte Halimione portulacoides, collected from Ria de Aveiro, Portugal. To determine their exact taxonomic position, comparative analyses were performed with these strains and closely related type strains of Salinicola species. Genome sequencing and comparison indicated that five of the seven isolated strains comprised distinct and novel species (average nucleotide identity <0.95; in silico DNA-DNA hybridization <70 %; G+C difference >1 %). Multilocus sequence analysis was performed using gyrB, rpoD and 16S rRNA gene sequences from the novel and type strains to determine their phylogenetic positions. The novel strains are facultative anaerobes, mesophilic, facultative alkaliphic and halophilic, test positive for catalase and oxidase activities, for hydrolysis of Tween 20 and phosphate, for production of indole-3-acetic acid, but do not produce H2S. Ubiquinone UQ-9 is present in major amounts in all strains. The major fatty acids include C16 : 0 and the summed feature containing C18 : 1ω7c and/or C18 : 1ω6c. The DNA G+C content ranges from 60.6 to 65.8 mol%. Five strains were confirmed as new species belonging to the genus Salinicola, for which the names Salinicolahalimionae sp. nov. (type strain CPA60T=CECT 9338T=LMG 30107T), Salinicolaaestuarinus sp. nov. (type strain CPA62T=CECT 9339T=LMG 30108T), Salinicolaendophyticus sp. nov. (type strain CPA92T=CECT 9340T=LMG 30109T), Salinicolahalophyticus sp. nov. (type strain CR45T=CECT 9341T=LMG 30105T) and Salinicola lusitanus sp. nov. (type strain CR50T=CECT 9342T=LMG 30106T) are proposed.

Abstract
Kushneria konosiri X49T is a member of the Halomonadaceae family within the order Oceanospirillales and can be isolated from salt-fermented larval gizzard shad. The genome of K. konosiri X49T reported here provides a genetic basis for its halophilic character. Diverse genes were involved in salt-in and -out strategies enabling adaptation of X49T to hypersaline environments. Due to resistance to high salt concentrations, genome research of K. konosiri X49T will contribute to the improvement of environmental and biotechnological usage by enhancing understanding of the osmotic equilibrium in the cytoplasm. Its genome consists of 3,584,631 bp, with an average G + C content of 59.1%, and 3261 coding sequences, 12 rRNAs, 66 tRNAs, and 8 miscRNAs.

Abstract
Two endophytic bacteria (EAod3T and EAod7T) were isolated from the aerial part of plants of Arthrocnemum macrostachyum growing in the Odiel marshes (Huelva, Spain). Phylogenetic analysis based on 16S rRNA gene sequences indicated their affiliation to the genus Kushneria. 16S rRNA gene sequences of strains EAod3T and EAod7T showed the highest similarity to Kushneria marisflavi DSM 15357T (99.0 and 97.6 %, respectively). Digital DNA-DNA hybridization studies between the draft genomes of strain EAod3T and K. marisflavi DSM 15357T corresponded to 28.5 % confirming the novel lineage of strain EAod3T in the genus Kushneria. Cells of both strains were Gram-staining-negative, aerobic and motile rods able to grow at 4-37 °C, at pH 5.0-8.0 and tolerate 0.5-25 % NaCl (w/v). They presented ubiquinone Q9 and C16 : 0, C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c as the major fatty acids. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Based on the phenotypic and phylogenetic results, strains EAod3T (=CECT 9073T=LMG 29856T) and EAod7T (=CECT 9075T=LMG 29858T) are proposed as new representatives of the genus Kushneria, and the proposed names are Kushneria phyllosphaerae sp. nov. and Kushneria endophytica sp. nov., respectively. The whole genome sequence of strain EAod3T has a total length of 3.8 Mbp and a G+C content of 59.3 mol%.

Abstract
We present the genome sequence of Kushneria marisflavi KCCM 80003T isolated from Yellow Sea in Korea. The complete genome of KCCM 80003T consisted of a single, circular chromosome of 3,667,185bp, with an average G+C content of 59.05%, and 3287 coding sequences, 12 rRNAs, and 66 tRNAs. Kushneria marisflavi KCCM 80003T, belonging to the family Halomonadaceae, exhibited resistance to high salt concentrations and possessed potassium metabolism- or osmotic stress-related coding sequences, including potassium homeostasis, ectoine biosynthesis and regulation, choline and betaine uptake, and betaine biosynthesis features in the genome. These results provide a basis for understanding resistance strategies to osmotic stress at the genetic level and accordingly have implications for genetic engineering and biotechnology.

Abstract
Halomonads are moderately halophilic bacteria that are studied as models of prokaryotic osmoadaptation and sources of enzymes and chemicals for biotechnological applications. Despite the progress in understanding the diversity of these organisms, our ability to explain ecological, metabolic, and biochemical traits of halomonads at the genomic sequence level remains limited. This study addresses this gap by presenting draft genomes of Salinicola socius SMB35T, Salinicola sp. MH3R3–1 and Chromohalobacter sp. SMB17, which were isolated from potash mine tailings in the Verkhnekamsk salt deposit area of Russia. The analysis of these genomes confirmed the importance of ectoines and quaternary amines to the capacity of halomonads to tolerate osmotic stress and adapt to hypersaline environments. The study also revealed that Chromohalobacter and Salinicola share 75–90% of the predicted proteome, but also harbor a set of genus-specific genes, which in Salinicola amounted to approximately 0.5 Mbp. These genus-specific genome segments may contribute to the phenotypic diversity of the Halomonadaceae and the ability of these organisms to adapt to changing environmental conditions and colonize new ecological niches.

Abstract
Members of the genus Halotalea (family Halomonadaceae) are of high significance since they can tolerate the greatest glucose and maltose concentrations ever reported for known bacteria and are involved in the degradation of industrial effluents. Here, the characteristics and the permanent-draft genome sequence and annotation of Halotalea alkalilenta AW-7T are described. The microorganism was sequenced as a part of the Genomic Encyclopedia of Type Strains, Phase I: the one thousand microbial genomes (KMG) project at the DOE Joint Genome Institute, and it is the only strain within the genus Halotalea having its genome sequenced. The genome is 4,467,826 bp long and consists of 40 scaffolds with 64.62 % average GC content. A total of 4,104 genes were predicted, comprising of 4,028 protein-coding and 76 RNA genes. Most protein-coding genes (87.79 %) were assigned to a putative function. Halotalea alkalilenta AW-7T encodes the catechol and protocatechuate degradation to β-ketoadipate via the β-ketoadipate and protocatechuate ortho-cleavage degradation pathway, and it possesses the genetic ability to detoxify fluoroacetate, cyanate and acrylonitrile. An emended description of the genus Halotalea Ntougias et al. 2007 is also provided in order to describe the delayed fermentation ability of the type strain.

Abstract
Halomonas zhanjiangensis Chen et al. 2009 is a member of the genus Halomonas, family Halomonadaceae, class Gammaproteobacteria. Representatives of the genus Halomonas are a group of halophilic bacteria often isolated from salty environments. The type strain H. zhanjiangensis JSM 078169(T) was isolated from a sea urchin (Hemicentrotus pulcherrimus) collected from the South China Sea. The genome of strain JSM 078169(T) is the fourteenth sequenced genome in the genus Halomonas and the fifteenth in the family Halomonadaceae. The other thirteen genomes from the genus Halomonas are H. halocynthiae, H. venusta, H. alkaliphila, H. lutea, H. anticariensis, H. jeotgali, H. titanicae, H. desiderata, H. smyrnensis, H. salifodinae, H. boliviensis, H. elongata and H stevensii. Here, we describe the features of strain JSM 078169(T), together with the complete genome sequence and annotation from a culture of DSM 21076(T). The 4,060,520 bp long draft genome consists of 17 scaffolds with the 3,659 protein-coding and 80 RNA genes and is a part of Genomic Encyclopedia of Type Strains, Phase I: the one thousand microbial genomes (KMG) project.

Abstract
Chromohalobacter salexigens is one of nine currently known species of the genus Chromohalobacter in the family Halomonadaceae. It is the most halotolerant of the so-called 'moderately halophilic bacteria' currently known and, due to its strong euryhaline phenotype, it is an established model organism for prokaryotic osmoadaptation. C. salexigens strain 1H11(T) and Halomonas elongata are the first and the second members of the family Halomonadaceae with a completely sequenced genome. The 3,696,649 bp long chromosome with a total of 3,319 protein-coding and 93 RNA genes was sequenced as part of the DOE Joint Genome Institute Program DOEM 2004.
