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).

An aerobic, spore-forming, moderately halophilic bacterium, strain BH260T, was isolated from a salt lake in China. Cells of this strain were found to be motile rods with flagella. The organism grew optimally at 30–32 °C and pH 8·0 in the presence of 12–15 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a clade with the type strains of the genus Lentibacillus. The levels of 16S rRNA gene sequence similarity for strain BH260T with respect to Lentibacillus salsus KCTC 3911T, Lentibacillus juripiscarius JCM 12147T and Lentibacillus salicampi KCCM 41560T were 96·0, 95·5 and 95·3 %, respectively. Chemotaxonomic data (a DNA G+C content of 44 mol%; MK-7 as the major isoprenoid quinone; A1γ-meso-diaminopimelic acid as the cell-wall type; phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids; anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 as the major fatty acids) also supported assignment of the isolate to the genus Lentibacillus. On the basis of physiological and molecular properties, the isolate represents a novel species within the genus Lentibacillus, for which the name Lentibacillus lacisalsi sp. nov. is proposed. The type strain is BH260T (=KCTC 3915T=DSM 16462T).

A Gram-staining-positive, moderately halophilic bacterium, designated strain Amb31T, was isolated from water of the hypersaline lake Aran-Bidgol in Iran and characterized taxonomically using a polyphasic approach. Cells were rods, motile and able to produce ellipsoidal endospores at a central position in swollen sporangia. Strain Amb31T was facultatively anaerobic and catalase- and oxidase-positive. The strain grew in a complex medium supplemented with 3–25 % (w/v) NaCl (optimum 7.5–10 %). Optimal growth was at 30–35 °C and pH 7.5. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that strain Amb31T belonged to the genus Lentibacillus; it exhibited 16S rRNA gene sequence similarity values of 96.8 and 96.4 % to Lentibacillus salicampi SF-20T and Lentibacillus salinarum AHS-1T, respectively, and values of 95.9–94.7 % to the type strains of other recognized species of Lentibacillus. The cell-wall peptidoglycan of strain Amb31T was based on meso-diaminopimelic acid and MK-7 was the respiratory isoprenoid quinone. The major fatty acids were anteiso-C15 : 0 (44.7 %), iso-C16 : 0 (21.4 %) and anteiso-C17 : 0 (15.9 %) and the polar lipid pattern consisted of phosphatidylglycerol, diphosphatidylglycerol, five phospholipids and a glycolipid. The DNA G+C content was 44.1 mol%. All these features confirmed the placement of strain Amb31T within the genus Lentibacillus and the strain could be clearly differentiated from strains of the other species of Lentibacillus on the basis of several phenotypic, genotypic and chemotaxonomic features. DNA–DNA relatedness with the type strain of the most closely related strain, L. salicampi DSM 16425T, was 28 %. Therefore, strain Amb31T represents a novel species of the genus Lentibacillus, for which the name Lentibacillus persicus sp. nov. is proposed.

Two Gram-positive, rod-shaped, spore-forming and moderately halophilic bacteria (strains 28-1T, 28-4), isolated from a soil sample from a neutral salt lake in Xin-Jiang, China, were characterized polyphasically. On the basis of fasta (ungapped) analyses of 16S rRNA gene sequences, strains 28-1T and 28-4 were shown to belong to the Bacillaceae and to be closely related to Filobacillus milensis DSM 13259T (97·0 %) and Bacillus haloalkaliphilus DSM 5271T (95·7 %). 16S rRNA gene sequence similarity with other recognized species was not more than 94·1 %. Phylogenetic, chemotaxonomic, physiological and biochemical data supported the differentiation of these novel strains from F. milensis and B. haloalkaliphilus. Therefore these two previously unidentified strains are considered to represent a new genus and species, for which the name Tenuibacillus multivorans gen. nov., sp. nov. is proposed. The type strain is 28-1T (=AS 1.3442T=NBRC 100370T).
