Paenibacillus piri sp. nov., isolated from urban soil.

A rod-shaped, Gram-stain-positive bacterial strain, MS74 ^T , was isolated from soil beside Itaewon road, Seoul, Republic of Korea. The strain could grow well on R2A, nutrient agar and tryptone soya agar, but not in LB agar. MS74 ^T tolerated 3.0 % NaCl (w/v), pH 9.0 and a temperature range from 10 to 35 °C (optimal temperature, 28 °C). From the comparison of 16S rRNA gene sequence, the strain is most closely related to Paenibacillus vulneris CCUG 53270 ^T , Paenibacillus esterisolvens CFH S0170 ^T , Paenibacillus rigui JCM 16352 ^T and Paenibacillus yunnanensis YN2 ^T with similarity percentages of 96.6 %, 96.4 %, 95.9 % and 95.8 % respectively. Major polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), and phosphatidylethanolamine (PE). The major menaquinone was MK-7. The fatty acids profile mainly consisted of C _15 : 0 anteiso, C _15 : 0 iso, C _16 : 0 iso, and C _16 : 0 . The DNA G+C content of the isolated strain determined from the whole-genome sequence was 51 mol%. MS74 ^T had an average nucleotide identity (ANI) value of 73.9 % and a digital DNA-DNA hybridization (dDDH) value of 20.6 % with most closely related strain, Paenibacillus vulneris CCUG 53270 ^T . On the basis of phenotypic, chemotypic and genotypic evidence, the isolate was identified as representing a novel species of the genus Paenibacillus , for which the name Paenibacillus piri sp. nov. is proposed. The type strain is MS74 ^T (=KACC 19385 ^T =DSM 105496 ^T ).
