Luteimonas lutimaris sp nov., isolated from a tidal flat

Abstract

A Gram-staining-negative, strictly aerobic bacterium, designated strain G3(T), 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 G3(T) was observed between 15 and 40 degrees C (optimum 30 degrees C) and between pH 5.5 and 9.0 (optimum pH 6.5-7.5). Strain G3(T) contained Q-8 as the predominant lipoquinone and iso-C(15:0), iso-C(17:1)omega 9c, iso-C(16:0) and iso-C(11:0) 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 G3(T) formed a tight phylogenetic lineage with Luteimonas mephitis B1953127.1(T) within the genus Luteimonas and was most closely related to L. mephitis B1953/27.1(T) with 98.0% 16S rRNA gene sequence similarity. The DNA DNA relatedness between strain G3(T) and L. mephitis B1953/27.1(T) was 35.2 +/- 3.3%. On the basis of chemotaxonomic data and molecular properties, strain G3(T) represents a novel species of the genus Luteimonas, for which the name Luteimonas lutimaris sp. nov. is proposed. The type strain is G3(T) ( KACC 14929(T)=JCM 16916(T)).
