Luteimonas notoginsengisoli sp. nov., isolated from rhizosphere

A Gram-staining-negative, yellow-pigmented strain, designated SYP-B804^T, was isolated from the rhizosphere of Panax notoginseng. The strain was rod-shaped with a single polar flagellum. The optimum temperature and pH required for growth of the strain were 28-32 °C and pH 7-8, respectively. 16S rRNA gene sequence analysis indicated that strain SYP-B804^T showed highest 16S rRNA gene sequence similarity with Luteimonas mephitis DSM 12574^T (98.0 %). However, the DNA-DNA relatedness value between them (38.1 ± 0.6 %) was less than the threshold value for the delineation of genomic species. Ubiquinone-8 (Q-8) was the predominant quinone. The major fatty acids were iso-C_15 : 0 and iso-C_17 : 1ω9c. The major polar lipids of the strain were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was 71 %. On the basis of phenotypic, chemotaxonomic and molecular characteristics, strain SYP-B804^T merits recognition as a representative of a novel species of the genus Luteimonas, for which the name Luteimonas notoginsengisoli sp. nov. is proposed, with SYP-B804^T ( = KCTC 42211^T = JCM 30329^T) as the type strain.
