Description of Luteimonas pelagia sp. nov., isolated from marine sediment, and emended descriptions of Luteimonas aquatica, Luteimonas composti, Luteimonas mephitis, Lysobacter enzymogenes and Lysobacter panaciterrae.

An aerobic, Gram-stain-negative, non-motile, rod-shaped bacterium, designated strain CC-VAM-7(T), was isolated from a marine sediment sample collected at Kending, Taiwan. The isolate grew optimally at pH 7.0 and 30 °C and in the presence of 4 % (w/v) NaCl. The most closely related strains in terms of 16S rRNA gene sequence similarity were the type strains of Luteimonas huabeiensis (95.2 %) and Lysobacter defluvii (95.0 %). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain CC-VAM-7(T) clustered with members of the genus Luteimonas. Strain CC-VAM-7(T) possessed C15 : 1ω5c, C16 : 1ω5c, iso-C11 : 0, iso-C15 : 0, iso-C16 : 0, iso-C17 : 0, iso-C11 : 0 3-OH and summed feature 9 (10-methyl C16 : 0 and/or iso-C17 : 1ω9c) as predominant fatty acids. The polar lipid profile contained major amounts of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine and moderate amounts of an unidentified phospholipid. The genomic DNA G+C content was 73.4 mol%. Ubiquinone 8 (Q-8) was the predominant respiratory quinone. According to its distinct phylogenetic, phenotypic and chemotaxonomic features, which were in line with those of other members of the genus Luteimonas, strain CC-VAM-7(T) is proposed to represent a novel species within the genus Luteimonas, for which the name Luteimonas pelagia sp. nov. is proposed. The type strain is CC-VAM-7(T) ( = BCRC 80558(T) = JCM 18792(T)). In addition, we propose emended descriptions of Luteimonas aquaticaChou et al. 2008, Luteimonas compostiYoung et al. 2007, Luteimonas mephitisFinkmann et al. 2000, Lysobacter enzymogenesChristensen and Cook 1978 and Lysobacter panaciterraeTen et al. 2009.
