Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="jobm201400940-sec-0001" sec-type="section"> <p>A Gram‐positive, facultative anaerobic, rod‐shaped, and endospore‐forming strain, designated 53‐2<sup>T</sup> was isolated from the root nodule of <italic>Oxytropis ochrocephala</italic> Bunge growing on Qilian mountain, China. The strain can grow at pH 7.0–8.0, 10–50 °C and tolerate up to 11% NaCl. Optimal growth occurred at pH 7.2 and 37 °C. The result of BLASTn search based on 16S rRNA gene sequence revealed that strain 53‐2<sup>T</sup>, being closest related to <italic>Bacillus acidicola</italic> 105‐2<sup>T</sup>, possessed remote similarity (less than 95.64%) to the species within genus <italic>Bacillus</italic>. The DNA G + C content was 37.8%. Chemotaxonomic data (major quinone is MK‐7; major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, unknown phospholipid, and aminoglycophospholipid; fatty acids are anteiso‐C<sub>15: 0</sub>, iso‐C<sub>15:0</sub> and anteiso‐C<sub>17: 0</sub>) supported the affiliation of the isolate to the genus <italic>Bacillus</italic>. On the basis of physiological, phylogenetic, and biochemical properties, strain 53‐2<sup>T</sup> represents a novel species within genus <italic>Bacillus</italic>, for which the name <italic>Bacillus radicibacter</italic> is proposed. The type strain is 53‐2<sup>T</sup> (=DSM27302<sup>T</sup>=ACCC06115<sup>T</sup>=CCNWQLS5<sup>T</sup>).</p> </sec> </abstract>
