Paenibacillus allorhizoplanae sp. nov. from the rhizoplane of a Zea mays root

Abstract : Abstract A Gram-positive staining, aerobic, endospore-forming bacterial strain, isolated from the rhizosphere of Zea mays was studied for its detailed taxonomic allocation. Based on the 16S rRNA gene sequence similarity comparisons, strain JJ-42 T was shown to be a member of the genus Paenibacillus , most closely related to the type strain of Paenibacillus pectinilyticus (98.8%). The 16S rRNA gene sequence similarity to all other Paenibacillus species was below 98.5%. The pairwise average nucleotide identity (ANI) and digital DNA−DNA hybridization (dDDH) values of the JJ-42 T genome assembly against publicly available Paenibacillus type strain genomes were below 92% and 47%, respectively. The quinone system of strain JJ-42 T consisted exclusively of menaquinone MK-7. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, three aminophospholipids (APL), and one unidentified lipid. The major fatty acids were iso- and anteiso-branched with the major compound anteiso C 15:0 . Physiological and biochemical characteristics allowed a further phenotypic differentiation of strain JJ-42 T from the most closely related species. Thus, JJ-42 T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus allorhizoplanae sp. nov. is proposed, with JJ-42 T (= LMG 32089 T = CCM 9085 T = DSM 111786 T = CIP 111891 T ) as the type strain.
