A Gram-stain-positive, rod-shaped, facultatively anaerobic bacterium, designated strain ES3-24(T), was isolated from a selenium mineral soil. The isolate endospore-forming, nitrate-reducing and motile by means of peritrichous flagella. major menaquinone 7 (MK-7) the predominant fatty acids (>5%) were anteiso-C15:0, iso-C16:0, C16:0 anteiso-C17:0. polar lipids diphosphatidylglycerol, phosphatidylethanolamine two unknown aminophospholipids. Strain ES3-24(T) contained meso-diaminopimelic acid in cell-wall peptidoglycan DNA G+C content 49.6 mol%. According to phylogenetic analysis based on 16S rRNA gene sequence, most closely related Paenibacillus terrigena A35(T), with sequence identity 98.3%, while other members genus had identities less than 95.0%. DNA-DNA relatedness between P. CCTCC AB206026(T) 39.3 %. In addition, showed obvious differences species lipids, nitrate reduction physiological biochemical characteristics. data our polyphasic taxonomic study reveal that represents novel Paenibacillus, for which name selenitireducens sp. nov. is proposed. type ( = KCTC 33157(T) AB2013097(T)).
