Abstract

Bacterial strain TM-1 was isolated from the gut of a wood-feeding termite, Snyder. Cells of strain TM-1 were Gram-negative, spherical (1.0–2.0 µm in diameter), non-motile, non-sporulating and red-pigmented. Strain TM-1 was resistant to UV radiation, showing 34 % survival after exposure to UV light at a dose of 100 J m. Growth occurred at 20–40 °C (optimum, 30 °C), at pH 6.0–10.0 (optimum, pH 6.0–7.0), and in the presence of 0–1 % (w/v) NaCl (optimum, 0–0.4 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TM-1 was related to members of the genus , with sequence similarities ranging from 87.0 to 94.0 %. The peptidoglycan of strain TM-1 contained ornithine, alanine, glycine and glutamic acid. The most abundant cellular fatty acids of strain TM-1 were summed feature 3 (Cω7 and/or Cω6; 22.3 %) and C (37.5 %). MK-8 was the predominant quinone. The polar lipid profile contained three glycophospholipids, six glycolipids, one aminolipid and three unknown lipids. DNA of the type strain had a G+C content of 65.6 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data presented, strain TM-1 represents a novel species of the genus , for which the name sp. nov. is proposed, with TM-1 ( = CGMCC 1.10218 = NBRC 106334) as the type strain.
