A novel, Gram-staining-negative, non-pigmented, rod-shaped, strictly aerobic, extremely halophilic bacterium, designated strain IA16T, was isolated from the mud of the hypersaline Lake Aran-Bidgol, in Iran. Cells of strain IA16T were not motile. Growth occurred with 2.5–5.2 M NaCl (optimum 3.4 M), at pH 6.0–8.0 (optimum pH 7.0) and at 30–50 °C (optimum 40 °C). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain IA16T belonged in the family Rhodospirillaceae and that its closest relatives were Rhodovibrio sodomensis DSM 9895T (91.6 % sequence similarity), Rhodovibrio salinarum NCIMB 2243T (91.2 %), Pelagibius litoralis CL-UU02T (88.9 %) and Fodinicurvata sediminis YIM D82T (88.7 %). The novel strain’s major cellular fatty acids were C19 : 0 cyclo ω7c and C18 : 0 and its polar lipid profile comprised phosphatidylglycerol, diphosphatidylglycerol, four unidentified phospholipids, three unidentified aminolipids and two other unidentified lipids. The cells of strain IA16T contained the ubiquinone Q-10. The G+C content of the novel strain’s genomic DNA was 67.0 mol%. The physiological, biochemical and phylogenetic differences between strain IA16T and other previously described taxa indicate that the strain represents a novel species in a new genus within the family Rhodospirillaceae , for which the name Limimonas halophila gen. nov., sp. nov. is proposed. The type strain of Limimonas halophila is IA16T ( = IBRC-M 10018T  = DSM 25584T).

A Gram-reaction-negative, strictly aerobic, non-motile, non-spore-forming and rod-shaped bacterial strain, designated THG-45T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 4–30 °C, at pH 5.5–9.0 and with 0–2 % (w/v) NaCl on nutrient agar. On the basis of 16S rRNA gene sequence similarity, strain THG-45T was shown to belong to the genus Pedobacter and was related to Pedobacter borealis G-1T (98.8 %), P. alluvionis NWER-II11T (97.9 %), P. agri PB92T (97.9 %), P. terrae DS-57T (97.5 %), P. suwonensis 15-52T (97.4 %), P. sandarakinus DS-27T (97.0 %) and P. soli 15-51T (97.0 %), but DNA relatedness between strain THG-45T and these strains was below 36 %. The G+C content of the genomic DNA was 39 mol%. The only isoprenoid quinone detected in strain THG-45T was menaquinone-7 (MK-7). The predominant fatty acids were iso-C15 : 0, summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c) and iso-C17 : 0 3-OH, and the major polar lipids were phosphatidylethanolamine and an unidentified aminophosphoglycolipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-45T to the genus Pedobacter , and a number of biochemical tests differentiated strain THG-45T from the recognized species of the genus Pedobacter . Therefore, the novel isolate represents a novel species, for which the name Pedobacter ginsenosidimutans sp. nov. is proposed, with THG-45T as the type strain ( = KACC 14530T = JCM 16721T).

Moderately Halophilic Bacterium

A novel Gram-stain-positive, moderately halophilic bacterium, designated strain G8BT, was isolated from water of the hypersaline lake Aran-Bidgol in Iran and characterized taxonomically using a polyphasic approach. Cells of strain G8BT were rod-shaped, motile and produced oval endospores at a terminal position in swollen sporangia. Strain G8BT was strictly aerobic, catalase-positive and oxidase-negative. The strain was able to grow at NaCl concentrations of 0.5–12.5 % (w/v), with optimum growth occurring at 5–7.5 % (w/v) NaCl. The optimum temperature and pH for growth were 35–40 °C and pH 7.5–8.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain G8BT was shown to belong to the genus Ornithinibacillus within the phylum Firmicutes and showed closest phylogenetic similarity with Ornithinibacillus bavariensis WSBC 24001T (97.6 %). The DNA G+C content of strain G8BT was 36.9 mol%. The major cellular fatty acids of strain G8BT were anteiso-C15 : 0, anteiso-C17 : 0, iso-C15 : 0 and iso-C16 : 0, and its polar lipid pattern consisted of phosphatidylglycerol, diphosphatidylglycerol, four unknown phospholipids and an unknown aminolipid. The isoprenoid quinones were MK-7 (98 %) and MK-8 (2 %). Strain G8BT contained a peptidoglycan of type A4β, l-Orn–d-Asp. All these features confirmed the placement of isolate G8BT within the genus Ornithinibacillus . DNA–DNA hybridization experiments revealed a low level of relatedness (6 %) between strain G8BT and Ornithinibacillus bavariensis DSM 15681T. On the basis of evidence from this study, a novel species of the genus Ornithinibacillus , Ornithinibacillus halophilus sp. nov., is proposed, with strain G8BT ( = IBRC-M 10683T = KCTC 13822T) as the type strain.

A prosthecate bacterial strain, designated G-192T, was isolated from decaying biomass of a haloalkaliphilic cyanobacterium Geitlerinema sp. Z-T0701. The cells were aerobic, Gram-negative, non-endospore-forming and dimorphic, occurring either as sessile bacteria with a characteristic stalk or as motile flagellated cells. The strain utilized a limited range of substrates, mostly peptonaceous, but was able to degrade whole proteins. Growth occurred at 5–46 °C (optimum, 35–40 °C), pH 7.3–10.3 (optimum, pH 8.0–9.0), 0–14 % NaCl (v/w; optimum, 2.0–6.0 %, v/w). The G+C content of the genomic DNA of strain G-192T was 66.8%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain G-192T formed a distinct evolutionary lineage within the family Hyphomonadaceae . Strain G-192T showed the highest 16S rRNA sequence similarity to Glycocaulis profundi ZYF765T (95.2%), Oceanicaulis stylophorae GISW-4T (94.2%) and Marinicauda salina WD6-1T (95.5%). The major cellular fatty acids (>5% of the total) were C18:1 ω9c, C18:0 and 11-methyl-C18:1 ω7c. The major polar lipids were glycolipids and phospholipids. The only respiratory quinone was ubiquinone-10 (Q-10). Based on polyphasic results including phylogenomic data, the novel strain could be distinguished from other genera, which suggests that strain G-192T represents a novel species of a new genus, for which the name Alkalicaulis satelles gen. nov., sp. nov. is proposed. The type strain is G-192T (=VKM B-3306T=KCTC 72746T). The strain is the first representative of the stalked bacteria associated with a haloalkaliphilic cyanobacterium. Based on phylogenomic indices and phenotypic data, it is proposed to evolve two novel families Maricaulaceae fam. nov. and Robiginitomaculaceae fam. nov. out of the current family Hyphomonadaceae . In addition, it is proposed to place the first two families in the novel order Maricaulales ord. nov. and novel order Hyphomonadales ord. nov. is proposed to accommodate the family Hyphomonadaceae .

A novel Gram-positive, slightly halophilic bacterium, designated strain B48T, was isolated from soil around the hypersaline lake Aran-Bidgol in Iran and characterized taxonomically using a polyphasic approach. Cells of strain B48T were non-motile rods and produced ellipsoidal endospores at a central or subterminal position in swollen sporangia. Strain B48T was a strictly aerobic bacterium, catalase- and oxidase-positive. The strain was able to grow at NaCl concentrations of 0.5–10.0 % (w/v), with optimum growth occurring at 2.5 % (w/v) NaCl. The optimum temperature and pH for growth were 35 °C and pH 7.5–8.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain B48T was shown to belong to the genus Bacillus within the phylum Firmicutes and showed the closest phylogenetic similarity to the species Bacillus foraminis CV53T (97.4 %) and Bacillus purgationiresistens DS22T (96.9 %). The DNA G+C content of this new isolate was 40.1 mol%. The major cellular fatty acids of strain B48T were iso-C15 : 0 and anteiso-C15 : 0, and its polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an aminophospholipid and two unknown phospholipids. The only quinone present was menaquinone 7 (MK-7). The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. All these features confirm the placement of isolate B48T within the genus Bacillus . DNA–DNA hybridization experiments revealed a low level of relatedness between strain B48T and Bacillus foraminis IBRC-M 10625T (8.1 %). On the basis of polyphasic evidence from this study, a new species of the genus Bacillus , Bacillus persicus sp. nov., is proposed, with strain B48T ( = IBRC-M 10115T = DSM 25386T = CECT 8001T) as the type strain.
