Moderately Halophilic Bacterium

A Gram-negative, facultatively anaerobic, short rod-shaped, heterotrophic bacterium, designated strain YIM D21T, was isolated from a salt mine in Yunnan province, south-west China. Strain YIM D21T formed cream–yellow colonies, was non-motile and moderately halophilic, and tolerated NaCl concentrations of 1–15 % (w/v), with optimum growth at 5–10 % (w/v). Growth occurred at 15–42 °C (optimum 28 °C) and at pH 6.5–8.5 (optimum 7.5–8.0). The respiratory quinone was ubiquinone-10 (Q-10). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, three unidentified phospholipids, one unidentified aminolipid and two unidentified lipids. The major fatty acids were C18 : 1ω7c and cyclo C19 : 0ω8c and the DNA G+C content was 67.7 mol%. Phylogenetic analyses revealed that strain YIM D21T belongs to the genus Roseivivax . 16S rRNA gene sequence similarities of YIM D21T were 95.7, 95.0 and 94.8 % with the type strains of Roseivivax halodurans , Roseivivax lentus and Roseivivax halotolerans , respectively. Physiological and biochemical tests allowed phenotypic differentiation of strain YIM D21T from closely related species with validly published names. We therefore propose that this isolate represents a novel species, Roseivivax sediminis sp. nov.; the type strain is YIM D21T ( = KCTC 23444T = ACCC 10710T).

Moderately Halophilic Bacterium

A Gram-stain-negative, moderately halophilic strain, designated strain L5T, was isolated from wetsalted hides collected from Chengdu, south-west PR China. The cells were motile, facultative aerobic, short rod-shaped and non-endospore-forming. Growth of strain L5T occurred at pH 6–10 (optimum, pH 8), 10–45 °C (optimum, 30 °C) and in the presence of 1–17 % (w/v) NaCl (optimum, 10 %). Results of phylogenetic analyses based on 16S rRNA, gyrB and rpoD gene sequences and its genome revealed that strain L5T belonged to the genus Halomonas . Strain L5T was found to be most closely related to the type strains of Halomonas saliphila , Halomonas lactosivorans , Halomonas kenyensis , Halomonas daqingensis and Halomonas desiderata (98.8, 98.6, 98.3, 97.9 and 97.4 % 16S rRNA gene sequence similarity, respectively). The draft genome was approximately 4.2 Mb in size with a G+C content of 63.5 mol%. The average nucleotide identity (ANI) and digital DNA–DNA hybridization values among strain L5T and the selected Halomonas species were 83.3–88.9 % (ANIm), 71.1–87.3 % (ANIb) and 20.2–34.6 %, which are below the recommended cutoff values. Major fatty acids were C16 : 0, C16 : 1  ω7c, C18 : 1  ω7c and C19 : 0 cyclo ω8c and the predominant ubiquinone was Q-9, with minor ubiquinone Q-8 also present. The phospholipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, four unidentified aminophospholipids and three unidentified phospholipids. Based on the mentioned polyphasic taxonomic evidence, strain L5T represents a novel species within the genus Halomonas , for which Halomonas pellis sp. nov. is proposed. The type strain is L5T (=CGMCC 1.17335T=KCTC 72573T).

Moderately Halophilic Bacterium

A moderately halophilic, Gram-stain-negative, non-sporulating bacterium designed as strain TYRC17T was isolated from olive-processing effluents. The organism was a straight rod, motile by means of peritrichous flagella and able to respire both oxygen and nitrate. Growth occurred with 0–25 % (w/v) NaCl (optimum, 7 %), at pH 5–11 (optimum, pH 7.0) and at 4–50 °C (optimally at 35 °C). It accumulated poly-β-hydroxyalkanoate granules and produced exopolysaccharides. The predominant fatty acids were C18 : 1ω7c, C16 : 1ω7c and C16 : 0. Ubiquinone 9 (Q-9) was the only respiratory quinone. The DNA G+C content of TYRC17T was 53.9 mol%. Phylogenetic analyses of 16S rRNA gene sequences revealed that the strain represents a member of the genus Halomonas and more precisely of the subgroup containing Halomonas sulfidaeris , H. titanicae , H. variabilis , H. zhanjiangensis , H. alkaliantarctica , H. boliviensis and H. neptunia . TYRC17T showed high 16S-rRNA sequence identities in particular with the three last species listed (99.4–99.5 %). A multilocus sequence analysis (MLSA) using the 23S rRNA, gyrB, rpoD and secA genes allowed clarifying the phylogenetic position of TYRC17T. This, combined with the level of DNA–DNA hybridization between TYRC17T and its closest relatives ranging from 21.6 % to 48.4 %, indicated that TYRC17T did not represent any of these species. On the basis of phenotypic and genotypic characteristics, and also genomic and phylogenetic evidence, it was concluded that strain TYRC17T represented a novel species of the genus Halomonas . The name Halomonas olivaria sp. nov. is proposed with TYRC17T ( = DSM 19074T = CCUG 53850BT) as the type strain.

An aerobic, Gram-stain-positive, endospore-forming, rod-shaped and moderately halophilic strain SKP4-6T, was isolated from shrimp paste (Ka-pi) collected from Samut Sakhon Province, Thailand. Phylogenetic analysis revealed that strain SKP4-6T belonged to the genus Halobacillus and was most closely related to Halobacillus salinus JCM 11546T (98.6 %), Halobacillus locisalis KCTC 3788T (98.6 %) and Halobacillus yeomjeoni KCTC 3957T (98.6 %) based on 16S rRNA gene sequence similarity. The digital DNA–DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain SKP4-6T and its related species were 18.2–19.3 % and 69.84–84.51 %, respectively, which were lower than the threshold recommended for species delineation. The strain grew optimally at 30–40 °C, at pH 7.0 and with 10–15 % (w/v) NaCl. It contained l-Orn–d-Asp in the cell wall peptidoglycan. The DNA G+C content was 44.8 mol%. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The predominant isoprenoid quinone was MK-7. Phosphatidylglycerol and diphosphatidylglycerol were present as major polar lipids. Based on this polyphasic approach, digital DNA–DNA relatedness and ANI values, strain SKP4-6T represents a novel species of the genus Halobacillus , for which the name Halobacillus fulvus sp. nov. is proposed. The type strain is SKP4-6T (=JCM 32624T=TISTR 2595T).

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 yellow-pigmented, motile, Gram-stain-negative, moderately halophilic and strictly aerobic bacterium, designated BA42AL-1T, was isolated from water of a saltern of Santa Pola, Alicante, Spain. Strain BA42AL-1T grew in media containing 5–20 % (w/v) salts (optimum 7.5 % salts). It grew between pH 6.0 and 9.0 (optimally at pH 7.5) and at 15–45 °C (optimally at 37 °C). Phylogenetic analysis based on the comparison of 16S rRNA gene sequences revealed that strain BA42AL-1T is a member of the genus Aquisalimonas . The closest relatives to this strain were Aquisalimonas halophila YIM 95345T and Aquisalimonas asiatica CG12T with sequence similarities of 99.4 % and 97.0 %, respectively. DNA–DNA hybridization between the novel isolate and Aquisalimonas halophila YIM 95345T revealed a relatedness of 54 %. The major fatty acids of strain BA42AL-1T were C18 : 1ω6c/C18 : 1ω7c, C19 : 0 cyclo ω8c and C16 : 0, and lower contents of C12 : 0 and C18 : 0. The polar lipid pattern of strain BA42AL-1T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylcholine, two glycolipids, a lipid and four unknown phospholipids. The G+C content of the genomic DNA of this strain was 65.0 mol%. Based on the DNA–DNA hybridization, phenotypic, chemotaxonomic and phylogenetic data presented in this study, strain BA42AL-1T is proposed as a novel species of the genus Aquisalimonas , for which the name Aquisalimonas lutea sp. nov. is suggested. The type strain is BA42AL-1T ( = CCM 8472T = CECT 8326T = LMG 27614T).

Moderately Halophilic Bacterium

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).

A pink-pigmented, facultatively methylotrophic bacterium, strain 23eT, was isolated from the leaves of Gnaphalium spicatum (cudweed). The cells of strain 23eT were Gram-reaction negative, motile and non-spore-forming rods. On the basis of 16S rRNA gene sequence similarities, strain 23eT was related to Methylobacterium organophilum ATCC 27886T (97.1 %) and Methylobacterium marchantiae JT1T (97 %), and the phylogenetic similarities to all other Methylobacterium species with validly published names were less than 97 %. Major cellular fatty acids were C18 : 1ω7c, C16 : 00 and C18 : 0. The results of DNA–DNA hybridization, phylogenetic analyses based on 16S rRNA and cpn60 gene sequences, fatty acid profiles, whole-cell matrix-assisted laser desorption/ionization time of flight/MS analysis, physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 23eT from the phylogenetically closest relatives. We propose that strain 23eT represents a novel species within the genus Methylobacterium , for which the name Methylobacterium gnaphalii sp. nov. is proposed. The type strain is 23eT ( = DSM 24027T = NBRC 107716T).

Two Gram-stain-negative, aerobic, moderately halophilic, rod-shaped bacteria (strains Ar-45T and DY470T) were isolated from seawater collected from the Southern Ocean and the Pacific Ocean, respectively. Growth of strain Ar-45T was observed with between 0.5 and 10.0 % (w/v) NaCl (optimally with 0.5–3.0 %) and between pH 5.5 and 9.5. Strain DY470T grew in the presence of 0.5–7.5 % (w/v) NaCl (optimally with 2.0 %) and at pH 5.5–8.5. Chemotaxonomic analysis showed Q-10 as the respiratory quinone for both strains. The major fatty acids (>5 %) of strain Ar-45T were C16 : 0, C19 : 0 cyclo ω8c and C18 : 1ω7c, while those of strain DY470T were C18 : 1ω7c, C16 : 0 and 11-methyl C18 : 1ω7c. The DNA G+C contents of the two strains were 62.0 and 61.8 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains Ar-45T and DY470T were related most closely to the genus Oceanicola , with sequence similarities of 97.4–94.0 and 97.7–94.7 %, respectively. The DNA–DNA hybridization value between strain Ar-45T and Oceanicola marinus LMG 23705T was 22.0 %. Levels of DNA–DNA relatedness between strain DY470T and Oceanicola nitratireducens LMG 24663T and Oceanicola batsensis DSM 15984T were 32.5 and 26.1 %, respectively. Based on phylogenetic, chemotaxonomic and phenotypic data, strains Ar-45T and DY470T are considered to represent two novel species of the genus Oceanicola , for which the names Oceanicola antarcticus (type strain Ar-45T = CGMCC 1.12662T = LMG 27868T) and Oceanicola flagellatus (type strain DY470T = CGMCC 1.12664T = LMG 27871T) are proposed.

In phylogenetic analyses based on 16S rRNA gene sequences, strain SW15T appeared to belong to the genus Idiomarina in the class Gammaproteobacteria and to be most closely related to Idiomarina homiensis PO-M2T (97.6 % sequence similarity). Strain SW15T exhibited optimal growth between 20 and 30 °C, with NaCl between 3 % and 4 % (w/v) and at a pH value between 7 and 8. Predominant cellular fatty acids were iso-C15 : 0 (31.1 %), iso-C17 : 0 (15.4 %), iso-C17 : 1ω9c (10.0 %) and C16 : 0 (8.8 %). The major respiratory quinone was ubiquinone Q-8. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylserine, an uncharacterized aminolipid and several uncharacterized phospholipids. The DNA G+C content was 51.1 mol%. The level of DNA–DNA relatedness between strain SW15T and Idiomarina homiensis PO-M2T was 42.6–56.5 %. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of the novel strain from established species of the genus Idiomarina . Based on the genotypic, phenotypic and chemotaxonomic data, strain SW15T represents a novel species in the genus Idiomarina , for which the name Idiomarina aquimaris sp. nov. is proposed, with SW15T ( = LMG 25374T = BCRC 80083T) as the type strain.
