Abstract
A novel Gram-stain-positive, facultatively aerobic, slightly halophilic, endospore-forming bacterium, designated G6-18T, was isolated from saline soil collected in Yingkou, Liaoning, PR China. Cells of strain G6-18T grew at 10-37 °C (optimum, 30 °C), at pH 6.0-9.0 (optimum, pH 8.0) and in the presence of 2-15 % (w/v) NaCl (optimum, 5 %). The strain could be clearly distinguished from the related species of the genus Paraliobacillus by its phylogenetic position and biochemical characteristics. It presented MK-7 as the major quinone and the dominant cellular fatty acids were iso-C16 : 0, anteiso-C15 : 0, C16 : 0 and iso-C14 : 0. The polar lipids consisted of diphosphatidylglycerol and phosphatidylglycerol as the major components. The G+C content of strain G6-18T genome was 35.3 mol%. 16S rRNA analysis showed that strain G6-18T had the highest similarity to Paraliobacillus ryukyuensis DSM 15140T, reaching 97.0 %, followed by Paraliobacillus quinghaiensis CGMCC 1.6333T with a value of 96.3 %. The average nucleotide identity values between strain G6-18T and Paraliobacillus ryukyuensis DSM 15140T, Paraliobacillus sedimins KCTC 33762T, Paraliobacillus quinghaiensis CGMCC 1.6333T and Paraliobacillus zengyii DSM 107811T were 74.3, 72.0, 73.2 and 72.8 %, respectively, and the digital DNA-DNA hybridization values between strain G6-18T and the neighbouring strains were 15.6, 13.8, 14.2 and 14.2 %, respectively. Based on phenotypic, chemotaxonomic and phylogenetic inferences, strain G6-18T represents a novel species of the genus Paraliobacillus, for which the name Paraliobacillus salinarum sp. nov. (=CGMCC 1.12058T=DSM 25428T) is proposed.

Abstract
A Gram-stain-positive, aerobic, rod-shaped, non-motile, endospore-forming and UV-resistant bacterial strain, designated strain TKL69T, was isolated from sandy soil sampled in the Taklimakan Desert. The strain grew at 20-50 °C, pH 6-9 and with 0-12 % (w/v) NaCl. The major fatty acids were anteiso-C15 : 0, iso-C15 : 0 and C16 : 0. The only respiratory quinone was MK-7. The cell-wall peptidoglycan was meso-diaminopimelic acid. Diphosphatidyl glycerol, two unidentified aminophospholipids and one unidentified phospholipid were identified as the major polar lipids. Genomic DNA analysis revealed a G+C content of 38.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain TKL69T has the highest similarity to Salinibacillus xinjiangensis CGMCC 1.12331T (96.9 %) but belongs to an independent taxon separated from other genera of the family Bacillaceae. Phylogenetic, phenotypic and chemotaxonomic analyses suggested that strain TKL69T represents a novel species of a new genus, for which the name Radiobacillus gen. nov., sp. nov. is proposed, with the type strain being Radiobacillus deserti TKL69T (=JCM 33497T=CICC 24779T).
