sp. nov., isolated from the rhizosphere of the coastal tidal-flat plant Free

Abstract

A Gram-negative, strictly aerobic, marine bacterium, designated strain CL-YJ9, was isolated from sediment closely associated with the roots of a plant () inhabiting a coastal tidal flat. Cells of the novel strain were straight and rod-shaped and were motile by means of monopolar flagella. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CL-YJ9 belongs to the genus and was most closely related to mano11 (94.1 % sequence similarity) and to other members of the genus (92.5–93.7 % sequence similarity). The strain grew with 1–5 % NaCl (optimum, 3 %) and at 5–30 °C (optimum, approx. 25 °C) and pH 6.0–9.0 (optimum, pH 7.0). The predominant cellular fatty acids were summed feature 3 (C 7 and/or iso-C 2-OH, 40.3 %), C 7 (26.6 %), C (16.6 %) and C 3-OH (7.1 %). The major isoprenoid quinone was Q-8. The G+C content of the genomic DNA was 61 mol%. On the basis of the data from this polyphasic study, strain CL-YJ9 belongs to the genus but is distinguishable from the recognized species. Strain CL-YJ9 therefore represents a novel species, for which the name sp. nov. is proposed. The type strain is CL-YJ9 (=KCCM 42386 =DSM 18822).
