Abstract

A Gram-staining-negative, rod-shaped, non-spore-forming bacterium, designated strain R27, was isolated from the moss , collected from Beijing Songshan National Nature Reserve, China, and characterized by using a polyphasic taxonomic approach. The predominant fatty acids of strain R27 were Cω7 (33.6 %), C (16.3 %), summed feature 3 (Cω7 and/or Cω6; 15.8 %) and C cyclo (8.7 %) and its major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, three uncharacterized aminolipids and an unknown phospholipid. Strain R27 contained Q-8 as the dominant isoprenoid quinone and the G+C content of its genomic DNA was 64.6 mol%. On the basis of 16S rRNA gene sequence comparison, strain R27 showed 99.1 % similarity to the closest related type strain, OP-1, and 97.6 % similarity to ATCC 29195. However, the DNA–DNA relatedness between strain R27 and CCTCC AB 2010354 and ATCC 29195 was 10.2 and 14.9 %, respectively. Based on 16S rRNA and gene sequence similarities and phenotypic and chemotaxonomic data, strain R27 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is R27 ( = CGMCC 1.11013  = DSM 25160).
