A Gram-positive, endospore-forming, rod-shaped bacterium, designated strain B519T, was isolated from a desert sand sample of Gansu Province, China. Strain B519T was strictly aerobic and cells were motile by means of peritrichous flagella. The strain grew optimally at 32–35 °C and pH 6.5–7.0. Chemotaxonomic data supported the affiliation of the new isolate to the genus Paenibacillus, including menaquinone-7 (MK-7) as the major isoprenoid quinone, DNA G+C content of 49.9 mol%, cell-wall type A1{gamma} (meso-diaminopimelic acid as the diagnostic diamino acid) and anteiso-C15 : 0, iso-C15 : 0, C16 : 0 and iso-C16 : 0 as the major fatty acids. Comparative 16S rRNA gene sequence analysis showed that strain B519T was most closely related to Paenibacillus alkaliterrae KSL-134T (98.0 % similarity). DNA–DNA relatedness between strain B519T and P. alkaliterrae KSL-134T was about 12.3 %. On the basis of phenotypic characteristics and molecular properties, strain B519T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus harenae sp. nov. is proposed. The type strain is B519T (=KCTC 3951T =DSM 16969T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain B519T is AY839867.

A transmission electron micrograph showing the general morphology of negatively stained cells of strain B519T and extended 16S rRNA gene sequence-based neighbour-joining and maximum-parsimony trees are available as supplementary material with the online version of this paper.
