Paenibacillus farraposensis sp. nov., isolated from a root nodule of Arachis villosa

Strain UY79 was isolated from a root nodule of , 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 3 % (w/v) NaCl (optimum, 1-2 %). Strain UY79 was facultative anaerobic, catalase-positive and oxidase-negative. According to the results of 16S rRNA gene sequence analysis, UY79 belongs to the genus and is closely related to MS2379 , BD-57 , ATCC 842 and PB172 , 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 38.2-48.7 %, respectively. Major fatty acids (>10 %) were anteiso-C , iso-C and C . 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 46.34 mol%. Based on the current polyphasic study, UY79 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is UY79 (=CCM 9147 =CGMCC 1.19038 ).
