Paenibacillus solisilvae sp. nov., isolated from birch forest soil.

A Gram-stain-positive, motile, rod-shaped bacterium, designated strain LAM7113T, was isolated from soil sample collected from a birch forest in Xinjiang Uygur Autonomous Region, PR China. Strain LAM7113T grew optimally at pH 8.0, 30 °C and in the presence of 1.0 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LAM7113T was closely related to members of the genus Paenibacillus , with the highest similarity to Paenibacillus baekrokdamisoli Back-11T (96.2 %). The genomic DNA G+C content was 43.4 mol%. The values of average nucleotide identity and DNA–DNA hybridization were 66.1 and 27.0 %, respectively, by comparing the draft genome sequences of strain LAM7113T and P. baekrokdamisoli Back-11T. Anteiso-C15 : 0 and iso-C15 : 0 were identified as the major cellular fatty acids. Menaquinone-7 was detected as the predominant respiratory quinone. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, three unidentified aminophospholipids, three unidentified glycolipids, one unidentified phospholipid and two unknown polar lipids. Based on its phenotypic, phylogenetic and chemotaxonomic characteristics, strain LAM7113T is proposed to represent a novel species of the genus Paenibacillus with the name Paenibacillus solisilvae sp. nov. The type strain is LAM7113T (=CGMCC 1.16619T=JCM 32513T).
