Luteimonas lutimaris sp. nov., isolated from a tidal flat
A Gram-staining-negative, strictly aerobic bacterium, designated strain G3T, was isolated from a tidal flat of the Taean coast in South Korea. Cells were moderately halotolerant and non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain G3T was observed between 15 and 40 °C (optimum 30 °C) and between pH 5.5 and 9.0 (optimum pH 6.5–7.5). Strain G3T contained Q-8 as the predominant lipoquinone and iso-C15 : 0, iso-C17 : 1ω9c, iso-C16 : 0 and iso-C11 : 0 as the major fatty acids. The G+C content of the genomic DNA was 69.6 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain G3T formed a tight phylogenetic lineage with Luteimonas mephitis B1953/27.1T within the genus Luteimonas and was most closely related to L. mephitis B1953/27.1T with 98.0 % 16S rRNA gene sequence similarity. The DNA–DNA relatedness between strain G3T and L. mephitis B1953/27.1T was 35.2±3.3 %. On the basis of chemotaxonomic data and molecular properties, strain G3T represents a novel species of the genus Luteimonas, for which the name Luteimonas lutimaris sp. nov. is proposed. The type strain is G3T ( = KACC 14929T = JCM 16916T).
