title: Luteimonas terrae sp. nov., isolated from rhizosphere soil of Radix ophiopogonis.
abstract: A Gram-staining-negative, strictly aerobic, rod-shaped and bright-yellow-pigmented bacterium, motile by means of a single polar flagellum, designated THG-MD21T, was isolated from rhizosphere soil of Radix ophiopogonis in Henan province, PR China. On the basis of 16S rRNA gene sequence similarity, strain THG-MD21T belongs to the genus Luteimonas and was most closely related to Luteimonas aestuarii B9T (98.2 % sequence similarity), Lysobacter panaciterrae Gsoil 068T (97.2 %) and Luteimonas marina FR1330T (97.0 %). The DNA G+C content was 64.4 mol%. The DNA-DNA relatedness between strain THG-MD21T and its closest phylogenetic neighbours was below 30.0 %. The only isoprenoid quinone detected in strain THG-MD21T was ubiquinone-8.The major polar lipids were found to be phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol, and the predominant fatty acids were iso-C11 : 0, iso-C15 : 0, iso-C16 : 0, C16 : 0 and iso-C17 : 1ω9c. The DNA-DNA hybridization result and characteristics revealed by a polyphasic study showed that strain THG-MD21T represents a novel species, for which the name Luteimonas terrae sp. nov. is proposed. The type strain is THG-MD21T ( = KACC 18131T = JCM 30122T).
