A taxonomic study was performed on strain HR1T, which was isolated from a desert soil sample collected from Xinjiang Province (China). Cells were aerobic, Gram-positive-staining, pink-pigmented, sporulating rods with a single lateral flagellum. The organism can grow at 15–42 °C and pH 5.0–10.0, optimally at 30–37 °C and pH 6.0–8.0. Growth is inhibited by 6 % NaCl. Analysis of almost-complete 16S rRNA gene sequence revealed that the isolate represents a distinct taxon within the genus Saccharibacillus; Saccharibacillus sacchari LMG 24085T was the nearest relative (97.9 % sequence similarity). DNA–DNA hybridization showed 29.6 % genetic relatedness between strain HR1T and S. sacchari LMG 24085T. The major isoprenoid quinone was MK-7 and the predominant fatty acid was anteiso-C15 : 0 (50.3 %). The G+C content of the DNA was 50.5 mol%. Therefore, based on phenotypic criteria and the phylogenetic position, strain HR1T belongs to a previously unidentified species of the genus Saccharibacillus, for which the name Saccharibacillus kuerlensis sp. nov. is proposed. The type strain is HR1T (=KCTC 13182T =JCM 14865T =CGMCC 1.6964T).
