A moderately halophilic, Gram-negative bacterium (strain CG4.1T), which was isolated from a solar saltern at Cabo de Gata, a wildlife reserve located in the province of Almería, southern Spain, was subjected to a polyphasic taxonomic study. This organism was an aerobic, motile rod that produced colonies with a yellow pigment. Strain CG4.1T grew at salinities of 3–25 % (w/v), at 15–45 °C and at pH 5–9. The organism reduced nitrate, hydrolysed starch and had phenylalanine deaminase activity. The major fatty acids were C18 : 1 ω7c, C16 : 0 and C19 : 0 cyclo ω8c. The DNA G+C content was 63.6 mol%. On the basis of phenotypic and phylogenetic data, strain CG4.1T appears to be a member of the genus Chromohalobacter and clustered closely with Chromohalobacter species, with 95–96 % similarity between their 16S rRNA gene sequences. However, DNA–DNA relatedness between the isolate and the type strains of Chromohalobacter species was low. Therefore, it is proposed that strain CG4.1T represents a novel species, Chromohalobacter salarius sp. nov. The type strain is strain CG4.1T (=CECT 5903T=LMG 23626T).

A moderately halophilic bacterium, strain CG2.1T, isolated from a solar saltern at Cabo de Gata, a wildlife reserve located in the province of Almería, southern Spain, was subjected to a polyphasic taxonomic study. This organism was an aerobic, motile, Gram-negative rod that produced orange-pigmented colonies. Strain CG2.1T was able to grow at salinities of 3–25 % (w/v) and at temperatures of 15–40 °C. The pH range for growth was 5–9. Strain CG2.1T was a heterotroph capable of utilizing various carbohydrates as carbon sources. The organism reduced nitrate and showed phenylalanine deaminase activity. The major fatty acids were C18 : 1 ω7c, C16 : 0 and C19 : 0 cyclo ω8c. The DNA G+C content was 60.9 mol%. On the basis of the phenotypic and phylogenetic data, strain CG2.1T appeared to be a member of the genus Halomonas and clustered closely with Halomonas marisflavi (97.1 % 16S rRNA gene sequence similarity). However, the level of DNA–DNA relatedness between the novel isolate and the most closely related Halomonas species was low. On the basis of these data, strain CG2.1T represents a novel member of the genus Halomonas, for which the name Halomonas indalinina is proposed. The type strain is CG2.1T (=CECT 5902T=LMG 23625T).

A Gram-staining-positive, moderately halophilic bacterium, designated strain NGS-2T, was isolated from sediment of a solar saltern pond located in Shinan, Korea. Strain NGS-2T was a strictly aerobic, non-motile rod that grew at pH 5.0–10.0 (optimum, pH 8.0), at 10–30 °C (optimum, 28 °C) and in the presence of 1–20 % (w/v) NaCl (optimum, 10 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain NGS-2T belonged to the genus Halobacillus, with sequence similarity of 98.4–95.8 % to existing type strains, showing the highest sequence similarity to Halobacillus dabanensis D-8T (98.4 %), H. litoralis SL-4T (98.4 %), H. trueperi SL-5T (98.2 %), H. faecis IGA7-4T (98.2 %), H. profundi IS-Hb4T (98.1 %) and H. mangrovi MS10T (98.0 %). The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidyl-N-methylethanolamine and an unknown glycolipid. The cell-wall peptidoglycan was based on l-Orn–d-Asp, the predominant isoprenoid quinone was menaquinone 7 (MK-7) and the major fatty acids were anteiso-C15: 0 and anteiso-C17: 0. The DNA G+C content of the novel isolate was 45.0 mol%. Levels of DNA–DNA relatedness between strain NGS-2T and the type strains of 12 other species of the genus ranged from 32 to 3 %. On the basis of the polyphasic analysis conducted in this study, strain NGS-2T represents a novel species of the genus Halobacillus, for which the name Halobacillus sediminis sp. nov. is proposed. The type strain is NGS-2T ( = KACC 18263T = NBRC 110639T).

A moderately halophilic, Gram-positive, rod-shaped bacterium (BH030004T) was isolated from a solar saltern in Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BH030004T belonged to the genus Pontibacillus. Chemotaxonomic data (DNA G+C content, 42 mol%; major isoprenoid quinone, MK-7; cell-wall type, A1γ-type meso-diaminopimelic acid; major fatty acids, iso-C15 : 0 and anteiso-C15 : 0) also supported the affiliation of the isolate to the genus Pontibacillus. Although the 16S rRNA gene sequence similarity between strain BH030004T and Pontibacillus chungwhensis DSM 16287T was relatively high (99·1 %), physiological properties and DNA–DNA hybridization (about 7 % DNA–DNA relatedness) allowed genotypic and phenotypic differentiation of strain BH030004T from the type strain of P. chungwhensis. Therefore, strain BH030004T represents a novel species of the genus Pontibacillus, for which the name Pontibacillus marinus sp. nov. is proposed. The type strain is BH030004T (=KCTC 3917T=DSM 16465T).

A moderately halophilic bacterium, strain SS20T, capable of growing at salinities of 1–20 % (w/v) NaCl was isolated from a solar saltern of the Dangjin area in Korea and was characterized taxonomically. Strain SS20T was a Gram-negative bacterium comprising motile, short rods. Its major cellular fatty acids were C18 : 1 ω7c, C19 : 0 ω8c cyclo and C16 : 0. The DNA G+C content was 70 mol% and the predominant ubiquinone was Q-9. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SS20T belonged to the genus Halomonas. The levels of 16S rRNA gene sequence similarity to the type strains of Halomonas species were in the range 93·0–97·5 %. The levels of DNA–DNA relatedness between strain SS20T and the type strains of phylogenetically closely related Halomonas species were in the range 5·3–12·3 %. On the basis of physiological and molecular properties, strain SS20T represents a novel species of the genus Halomonas, for which the name Halomonas koreensis sp. nov. is proposed. The type strain is SS20T (=KCTC 12127T=JCM 12237T).

Moderately Halophilic Bacterium

A moderately halophilic, Gram-negative bacterium, strain BH539T, which was isolated from a solar saltern at Taean in Korea, was considered to be a member of the genus Halomonas. Strain BH539T grew at salinities of 1–25 % (w/v) and at temperatures of 10–45 °C. Cells were short rods that were motile by means of several flagella. Their major fatty acids were C18 : 1 ω7c, C16 : 0 and C19 : 0 cyclo ω8c. The genomic DNA G+C content was about 65 mol% and the predominant ubiquinone was Q-9. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the isolate formed a branch of the species Cobetia marina. However, 23S and 16S rRNA gene sequence similarities revealed that strain BH539T was related more closely to the type strains of the genus Halomonas. Phylogenetic analyses based on 23S rRNA gene sequences also indicated that the strain formed a phyletic line within the genus Halomonas. Therefore, it was concluded that strain BH539T should be classified within the genus Halomonas, rather than Cobetia. On the basis of physiological and molecular properties, strain BH539T represents a novel species of the genus Halomonas, for which the name Halomonas taeanensis sp. nov. is proposed. The type strain is BH539T (=KCTC 12284T=DSM 16463T).

Moderately Halophilic Bacterium

A Gram-staining-positive, moderately halophilic bacterium, designated strain BH097T, was isolated from solar saltern soil of Bigeum Island in south-west Korea. Cells were motile rods, producing spherical endospores at a terminal position in swollen sporangia. Strain BH097T was strictly aerobic, grew at pH 5.5–9.5 (optimum, pH 8.0), at 10–52 °C (optimum, 37 °C) and at salinities of 1–22 % (w/v) NaCl (optimum, 7 % NaCl). On the basis of 16S rRNA gene sequence analysis, strain BH097T was shown to belong to the genus Gracilibacillus within the phylum Firmicutes , and showed closest sequence similarity to Gracilibacillus saliphilus DSM 19802T (95.8 %), Gracilibacillus thailandensis TP2-8T (95.6 %), Gracilibacillus boraciitolerans DSM 17256T (95.5 %), ‘Gracilibacillus quinghaiensis’ DSM 17858 (95.4 %) and Gracilibacillus halophilus DSM 17856T (95.2 %). The DNA G+C content of this novel isolate was 37.9 mol%. The major cellular fatty acids of strain BH097T were anteiso-C15 : 0, iso-C15 : 0 and C16 : 0, and its polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol two unknown phospholipids and a glycolipid. The isoprenoid quinone was MK-7, and the peptidoglycan type was A1γ, with meso-diaminopimelic acid as the diagnostic diamino acid. On the basis of polyphasic evidence from this study, strain BH097T represents a novel species of the genus Gracilibacillus for which the name Gracilibacillus bigeumensis sp. nov. is proposed. The type strain is BH097T ( = KCTC 13130T = DSM 19028T).
