abstract= A Gram-positive, halophilic bacterium was isolated from a sediment sample from Ai-Ding salt lake in China. The isolate, designated strain 17-5T, grew at salinities of 8–33 % (w/v) NaCl (optimally at 12 %, w/v). The genomic DNA G+C content of strain 17-5T was 48.1 mol%. The predominant isoprenoid quinone was MK-7(H2) and the cell-wall peptidoglycan contained meso-diaminopimelic acid. The major polar lipids were diphosphatidylglycerol and an unidentified glycolipid. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and C16 : 0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 17-5T was a member of the genus Bacillus, being most closely related to Bacillus qingdaonensis JCM 14087T (96.0 % sequence similarity) and Bacillus salarius DSM 16461T (95.6 %). The levels of 16S rRNA gene sequence similarity with respect to other Bacillus species were less than 91.7 %. Comparative analysis of the 16S rRNA gene sequence data, chemotaxonomy and phenotypic features of the novel isolate and related species of Bacillus indicated that strain 17-5T represents a novel species within the genus Bacillus, for which the name Bacillus aidingensis sp. nov. is proposed. The type strain is 17-5T (=CGMCC 1.3227T=DSM 18341T).,
