sp. nov., an endophytic bacterium isolated from roots of L. Free

Abstract

A novel endophytic bacterium, designated strain EGI 6500252, was isolated from the surface-sterilized roots of a medicinal plant ( L.) collected from Urumqi city, Xinjiang, north-west China. Cells were Gram-stain-positive, non-motile, aerobic, catalase- and oxidase-positive, rod-shaped and did not display spore formation. Strain EGI 6500252 grew at 10–40 °C (optimum 25–30 °C), at pH 6.0–8.0 (optimum pH 7.0) and in the presence of 0–10 % (w/v) NaCl (optimum 0–3 %). The major cellular fatty acids (>10 %) were identified as iso-C, anteiso-C, anteiso-C and summed feature 4. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unknown phospholipids, one unknown glycolipid and one unknown lipid. The dominant isoprenoid quinone was menaquinone 7 (MK-7). The DNA G+C content was 39.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain EGI 6500252 belonged to the genus , and exhibited a highest 16S rRNA gene sequence similarity (96.2 %) that was lower than the suggested threshold (97.0 %) for separating bacterial species. On the basis of the phylogenetic analysis, chemotaxonomic data and physiological characteristics, strain EGI 6500252 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is EGI 6500252 (=CGMCC 1.12820=KCTC 33514).
