A Gram-positive, rod-shaped, motile, spore-forming bacterium, strain SA-7-6T, was isolated from desert soil in China and was subjected to a polyphasic taxonomic study. The strain grew optimally at pH 7.5 and 37 °C. The G+C content of the genomic DNA of strain SA-7-6T was 53.7 mol%. The predominant menaquinone was MK-7. The major cellular fatty acid was anteiso-C15 : 0. Strain SA-7-6T contained meso-diaminopimelic acid in the cell-wall peptidoglycan. 16S rRNA gene sequence analysis showed that the new isolate shared highest similarity with Paenibacillus glycanilyticus JCM 11221T (96.6 %) and Paenibacillus daejeonensis KCTC 3745T (96.6 %). Based on morphological, physiological, chemotaxonomic and phylogenetic characteristics, strain SA-7-6T is considered to represent a novel species of the genus Paenibaillus, for which the name Paenibacillus tarimensis sp. nov. is proposed. The type strain is SA-7-6T (=CCTCC AB 206108T=DSM 19409T).
