Moderately Halophilic Bacterium

A Gram reaction-positive, moderately halophilic bacterium, designated H57B72T, was isolated from subsurface saline soil of Qaidam basin in the Qinghai province, China. Cells were rod-shaped, strictly aerobic, spore-forming and motile. The isolate grew optimally at 9 % (w/v) NaCl, pH 7.5 and 30 °C. The cell-wall peptidoglycan of strain H57B72T contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids were anteiso-C15 : 0 (59.97 %) and anteiso-C17 : 0 (17.14 %). Phosphatidylglycerol, diphosphatidylglycerol and a glycolipid were found to be the predominant polar lipids. The genomic DNA G+C content of strain H57B72T was 37.1 mol%. 16S rRNA gene sequence analysis showed that strain H57B72T was a member of the genus Virgibacillus and was most closely related to Virgibacillus salinus DSM 21756T (98.3 % gene sequence similarity). The level of DNA–DNA relatedness between strain H57B72T and V. salinus DSM 21756T was 8.5 %. Based on the phenotypic, genotypic and phylogenetic data presented, strain H57B72T represents a novel species, for which the name Virgibacillus subterraneus sp. nov. is proposed. The type strain is H57B72T (=DSM 22441T =CGMCC 1.7734T).

A Gram-stain-positive, rod-shaped, non-sporulating, motile and moderately halophilic bacterium, designated strain H96B60T, was isolated from a saline soil sample of the Qaidam basin, China. The strain was facultatively anaerobic. Major end products formed from glucose fermentation were acetate, ethanol and lactic acid. The cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The isoprenoid quinone component was menaquinone-6 (MK-6). The predominant cellular fatty acids were C16 : 0, anteiso-C13 : 0 and anteiso-C15 : 0. The genomic DNA G+C content of strain H96B60T was 36.2 mol%. Phylogenetic analysis based on comparative 16S rRNA gene sequences indicated that strain H96B60T represented a novel phyletic lineage within the family Bacillaceae and was related most closely to Halolactibacillus species (96.1–96.4 % similarity). Based on the phenotypic, chemotaxonomic and phylogenetic data presented, strain H96B60T is considered to represent a novel species of a new genus, for which the name Streptohalobacillus salinus gen. nov., sp. nov. is proposed.

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).

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.

Moderately Halophilic Bacterium

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 BH169T, capable of growing at salinities of 3–20 % (w/v) NaCl was isolated from a saline lake in China. Strain BH169T was strictly aerobic, short-rod-shaped and non-motile (non-flagellated). Its major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C15 : 0 and iso-C16 : 0. The genomic DNA G+C content was about 43 mol% and the predominant quinone was MK-7. The cell-wall peptidoglycan was of the A1γ type, containing meso-diaminopimelic acid as the diagnostic diamino acid. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a distinct phylogenetic line within the spore-forming rods of the genus Bacillus. The levels of 16S rRNA gene sequence similarity to the type strains of Bacillus species were below 93 %. On the basis of phenotypic and molecular properties, strain BH169T (=KCTC 3912T=DSM 16461T) represents the type strain of a novel species within the genus Bacillus, for which the name Bacillus salarius sp. nov. is proposed.
