sp. nov. isolated from roots.

An aerobic, Gram-staining-positive, endospore-forming bacterium, isolated from the rhizosphere of roots of maize (), was taxonomically studied. On the basis of 16S rRNA gene sequence similarity comparisons, strain JJ-125 clustered together with species of the genus and showed the highest similarities with (98.7 %). The 16S rRNA gene sequence similarities to the sequences of the type strains of other species of the genus were <98.4 %. The genome sequence of JJ-125 was 4 516 360 bp long and had a DNA G+C content of 37.3 %. A DNA-DNA hybridization with the type strain of DSM 23010 resulted in values of 42.3 and 43.9 % (reciprocal). The average nucleotide identity, average amino acid identity and digital DNA-DNA hybridization values between the JJ-125 genome assembly and those of the other type strains of species of the genus were <75%, <80 % and <21 %, respectively. Chemotaxonomic features supported the grouping of the strain with the genus e.g. the major fatty acids included iso-C iso-C ω10 and iso-C, the polar lipid profile contained the major components diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, the only quinone was menaquinone MK-7 and the characteristic diamino acid was -diaminopimelic acid. Physiological and biochemical test results were also different from those of the most closely related species. As a consequence, JJ-125 represents a novel species of the genus , for which we propose the name sp. nov., with JJ-125 (= CIP 111883 = LMG 32156 = CCM 9046) as the type strain.
