    Abstract:
    Two Gram-stain-positive, aerobic, non-motile, bacterial strains were isolated from symptomatic bark tissue of Populus × euramericana canker. The isolates were able to grow between 10 and 37 °C, at pH 6-10 and with 0-4 % (w/v) NaCl, with optimal growth at 28-30 °C, pH 7.0-8.0 and with 2 % (w/v) NaCl The strains were found to be oxidase and catalase positive. The menaquinone of strain 26D10-3-4T was MK-7 and the peptidoglycan type A3α based on l-Lys-Gly3-?Ala. The polar lipid profiles of strain 26D10-3-4T showed diphosphatidylglycerol, phosphatidylglycerol, two unidentified phospholipids and three unidentified glycolipids, and the major fatty acids found were anteiso-C15 : 0, iso-C15 : 0, iso-C17 : 0 and anteiso-C17 : 0. The DNA G+C content was 38.2 mol%. The two novel isolates shared the highest 16S rRNA gene sequence similarity with Salinicoccus qingdaonensis ZXM223T (95.0 %). Based on phenotypic and genotypic characteristics, these two strains represent a novel species of a new genus of the family Staphylococcaceae; the name Corticicoccus populi gen. nov., sp. nov. is proposed. The type strain of the type species is 26D10-3-4T (=CFCC 12725T=KCTC 33575T). An additional strain of the species is 9-4-1.
