ABSTRACT
Strain UY79T was isolated from a root nodule of Arachis villosa, collected at the Esteros de Farrapos National Park, Río Negro, Uruguay. Cells were non-motile Gram-variable rods with central to subterminal oval to ellipsoidal endospores that swell the sporangia. Growth was observed in the range of 15-42 °C (optimum, 30 °C), pH 5.0-9.0 (optimum, pH 7.0-8.0) and with up to 3â% (w/v) NaCl (optimum, 1-2â%). Strain UY79T was facultative anaerobic, catalase-positive and oxidase-negative. According to the results of 16S rRNA gene sequence analysis, UY79T belongs to the genus Paenibacillus and is closely related to P. ottowii MS2379T, P. peoriae BD-57T, P. polymyxa ATCC 842T and P. brasilensis PB172T, exhibiting 99.4, 99.0, 99.0 and 98.9% sequence identity, respectively. Average nucleotide identity and digital DNA-DNA hybridization values with the most closely related type strains were 74.3-88.6% and 38.2-48.7â%, respectively. Major fatty acids (>10â%) were anteiso-C150, iso-C150, and C16ââ0. Menaquinones MK-7 and MK-6 were the only isoprenoid quinones detected. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified glycolipid. Spermidine was the predominant polyamine. The DNA G+C content based on the draft genome sequence was 46.34âmol%. Based on the current polyphasic study, UY79T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus farraposensis sp. nov. is proposed. The type strain is UY79T (=CCM 9147T=CGMCC 1.19038T).
