Four Gram-stain-positive, aerobic, motile bacterial strains were isolated from the bark tissue of Populus × euramericana canker. Growth occurred between 10 and 37 °C and at pH 6-10, with optimal growth at 28-30 °C and pH 7.0-8.0. Growth occurred at 0-3 % (w/v) salinity. The strains were positive for oxidase and catalase activity. The major fatty acids were anteiso-C15 : 0 and C16 : 0. The phospholipid profiles contained diphosphatidylglycerol, phosphatidylinositol, phosphatidylglycerol, two phospholipids and five glycolipids. The peptidoglycan type was A4α, which is based on l-Lys-d-Ser-d-Asp. The DNA G+C content was 58.5 mol%. Based on 16S rRNA gene sequence analysis, as well as physiological and biochemical characteristics, the strains are considered to represent a novel species of a new genus in the family Jonesiaceae. The name proposed is Populibacterium corticicola gen. nov., sp. nov. The type strain of Populibacterium corticicola is 2D-4T (=CFCC 11886T=KCTC 33576T).
