Paenibacillus ferrarius sp nov., isolated from iron mineral soil

A Gram-reaction-positive, endospore-forming, aerobic bacterium, designated strain CY1(T), was isolated from iron mineral soil of Hunan Province, China. The isolate was rod-shaped and motile by means of peritrichous flagella. The major cellular fatty acids were anteiso-C-15:0 and iso-C-16:0 and the major quinone was menaquinone 7. The major polar lipids were phosphatidylglycerol and diphosphatidylglycerol phosphatidylethanolamine. The genomic DNA G+C content was 50.5 mol% and the major diagnostic diamino acid in cell-wall peptidodycan was mesodiaminopimelic acid. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that strain CY1(T) is most closely related to Paenibacillus chondroitinus DSM 5051(T) (97.7% 16S rRNA gene sequence similarity), Paenibacillus pocheonensis Gsoil 1138(T) (97.4%) and Paenibacillus frigoriresistens YIM 016(T) (97.0%). DNA-DNA hybridization dissociation values were lower than 490/o with the most closely related species. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence, strain CY1(T) is affiliated to the genus Paenibacillus, but could be distinguished from the species of this genus. A novel species with the name Paenibacillus ferrarius sp. nov. is proposed. The type strain is CY1(T) (=KCTC 33419(T)=CCTCC AB 2013369(T)).
