title: Paenibacillus wulumuqiensis sp. nov. and Paenibacillus dauci sp. nov., two novel species of the genus Paenibacillus.
abstract: Two Gram-staining-positive, aerobic, motile, endospore-forming, rod-shaped bacteria, designated strains Y24(T) and H9(T) were isolated from cold spring and carrot (Daucus L.) samples, respectively, in Xinjiang Uyghur Autonomous Region, north-western China. The taxonomic positions of the two new isolates were determined by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences and DNA-DNA hybridizations showed that strains Y24(T) and H9(T) were two different novel species belonging to the genus Paenibacillus, with Paenibacillus hunanensis FeL05(T) as their closest relative. The genomic DNA G + C contents of the two isolates Y24(T) and H9(T) were 48.1 and 46.6 mol %, respectively. The cell wall peptidoglycan contained meso-diaminopimelic acid. The predominant menaquinone was both as MK-7. The major cellular fatty acids were anteiso-C15:0, C16:0, iso-C16:0, anteiso-C17:0 and iso-C15:0. The polar lipid profiles consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and two glycolipids as the major components. On the basis of their phenotypic characteristics, the two isolates represent two different novel species of the genus Paenibacillus, for which the names Paenibacillus wulumuqiensis sp. nov. (type strain Y24(T) = CPCC 100602(T) = JCM 30284(T)) and Paenibacillus dauci sp. nov. (type strain H9(T) = CPCC 100608(T) = JCM 30283(T)) are proposed.
