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).

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 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).

Moderately Halophilic Bacterium

A moderately halophilic bacterium (strain RS-16T) was isolated from saline soil in Rambla Salada, a Mediterranean hypersaline rambla in Murcia, south-east Spain. Cells of strain RS-16T were Gram-negative rods, oxidase-negative and motile by peritrichous flagella. Strain RS-16T required NaCl for growth, and grew between 1 % and 30 % (w/v) NaCl (optimum, 5–7.5 %), at temperatures of between 4 °C and 41 °C (optimum, 32–37 °C), and at pH values of between 5 and 10 (optimum, pH 7). Strain RS-16T was chemo-organotrophic and its metabolism was respiratory with oxygen and nitrate as terminal electron acceptors. It produced acids from d-glucose and myo-inositol, accumulated poly-β-hydroxyalkanoate granules and produced cream colonies on MY 7.5 % (w/v). The DNA G+C content of strain RS-16T was 56.2 mol%. A comparison of 16S rRNA gene sequences confirmed the relationship of strain RS-16T to species of the genus Halomonas . The most phylogenetically related species was Halomonas cerina SP4T (97.4 %16S rRNA gene sequence similarity). In DNA–DNA hybridization assays strain RS-16T showed DNA–DNA relatedness values of 62.7±3.09 %, 64.5±1.97 % and 64.7±1.74 % to Halomonas cerina CECT 7282T, Halomonas cerina CECT 7284 and Halomonas cerina CECT 7283, respectively. The major fatty acids of strain RS-16T were C18 : 1ω7c and C16 : 0, and the predominant respiratory lipoquinone was ubiquinone, with nine isoprene units (Q-9). On the basis of these data, strain RS-16T is considered to represent a novel species of the genus Halomonas , for which the name Halomonas ramblicola sp. nov. is proposed. The type strain is RS-16T ( = CECT 7896T = LMG 26647T).
