title: Paenibacillus marchantiophytorumsp. nov., isolated from the liverwortHerbertus sendtneri.
abstract: A Gram-stain-positive, aerobic, motile, rod-shaped, endospore-forming bacterium, designated strain R55T, was isolated from the liverwortHerbertus sendtnerigrowing at Gawalong glacier, Tibet, and characterized by using a polyphasic taxonomic approach. The major fatty acids of strain R55Twere anteiso-C15 : 0, C16 : 0and iso-C16 : 0. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the predominant polar lipids and occurred along with two unidentified aminophospholipids, one unidentified phospholipid and one unidentified aminolipid. Strain R55Tcontained MK-7 as the dominant menaquinone andmeso-diaminopimelic acid as the major diagnostic diamino acid in the cell-wall peptidoglycan. The G+C content of the genomic DNA was 36.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain R55Twas affiliated to species of the genusPaenibacillus, and was related most closely toPaenibacillus ferrariusCY1T(97.1 % similarity). However, the DNA-DNA relatedness between this strain and strain R55Twas only 44.1 %. Based on phenotypic, chemotaxonomic and phylogenetic properties, strain R55Tis considered to represent a novel species of the genusPaenibacillus, for which the namePaenibacillus marchantiophytorumsp. nov. is proposed. The type strain is R55T( = CGMCC 1.15043T= DSM 29850T).
