Abstract

Bacterial strain A37T2 was isolated from the endophytic microbial community of a tree trunk and characterized. Strain A37T2 was Gram-stain-negative, formed rod-shaped cells, and grew optimally at 26–30 °C and at pH 5.5–7.5. The G+C content of the DNA was 46.6 mol%. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were Cω5 and iso-C, representing 61.7 % of the total fatty acids. The polar lipids consisted of phosphatidylethanolamine, four unidentified aminophospholipids, one unidentified phospholipid, two unidentified aminolipids and three unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain A37T2 belonged to the family , forming a distinct branch with JS13-10 within the genus . Strain A37T2 shared between 92.7 and 95.1 % 16S rRNA gene sequence similarity with the type strains of species of the genus . The phylogenetic, phenotypic and chemotaxonomic data presented indicate that strain A37T2 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is A37T2 ( = CIP 110584 = LMG 27458). An emended description of JS13-10 is also proposed.
