abstract= A Gram-stain-positive, facultatively anaerobic and rod-shaped bacterium, designated strain xj7T, was isolated from roots of Typha angustifolia L. growing in Beijing Cuihu Wetland, China. The isolate was identified as a member of the genus Paenibacillus based on phenotypic characteristics and phylogenetic inference. The novel strain was spore-forming, motile, catalase-positive and oxidase-negative. Optimal growth of strain xj7T occurred at 28–30 °C and pH 7.0–7.5. Diphosphatidylglycerol was the most abundant polar lipid and occurred along with phosphatidylglycerol, phosphatidylethanolamine, one unknown phospholipid and three unknown aminophospholipids. The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid. The predominant isoprenoid quinone was MK-7. The major fatty acid components were anteiso-C15 : 0 (56.1 %), iso-C16 : 0 (9.1 %), C16 : 0 (8.0 %), iso-C14 : 0 (6.3 %) and iso-C15 : 0 (5.1 %). The G+C content of genomic DNA was 47.9 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain xj7T fell within the evolutionary radiation encompassed by the genus Paenibacillus , its closest neighbours were Paenibacillus borealis KK19T (97.5 %) and Paenibacillus durus DSM 1735T (97.1 %). However, the DNA–DNA relatedness values between strain xj7T and P. borealis KK19T and between strain xj7T and P. durus DSM 1735T, were both 35 %. Based on phenotypic, chemotaxonomic and phylogenetic properties, strain xj7T is considered to represent a novel species of the genus Paenibacillus , for which the name Paenibacillus typhae sp. nov. is proposed. The type strain is xj7T ( = CGMCC 1.11012T = DSM 25190T).,
