A Gram-positive, facultatively anaerobic, agar-hydrolytic and rod-shaped bacterium with peritrichous flagellation, designated strain SCIV0701T, was isolated from soya bean rhizosphere soil collected from Bazhong, Sichuan Province, PR China and characterized by using polyphasic taxonomy. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCIV0701T belonged to the genus Paenibacillus, and showed highest similarity to Paenibacillus nanensis MX2-3T (97.59 %), Paenibacillus paeoniae M4BSY-1T (97.45 %) and Paenibacillus pinisoli NB5T (97.45 %). The average nucleotide identity values and in silico DNA-DNA hybridization scores between strain SCIV0701T and P. nanensis MX2-3T, P. paeoniae M4BSY-1T and P. pinisoli NB5T were lower than recommended thresholds of 95% and 70 %, respectively, for species delineation. Menaquinone-7 was the predominant respiratory quinone. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, two unidentified phospholipids and one unidentified aminophospholipid. The major fatty acids were anteiso-C15 : 0, C16 : 00 and iso-C16 : 0. Physiological and biochemical features differentiated strain SCIV0701T from the closely related Paenibacillus species. Based on the results of polyphasic taxonomic analysis, strain SCIV0701T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus soyae sp. nov. is proposed. The type strain is SCIV0701T (=GDMCC 1.2482T=JCM 34672T).
