Abstract: 
A cream-coloured, Gram-negative, aerobic, non-motile moderately thermophilic, rod-to-irregular-shaped bacterium, CC-GIMAT-2(T), was isolated from a coastal hot spring of Green Island (Lutao), located off Taituang, Taiwan, on marine agar 2216. The 16S rRNA gene sequence analysis and subsequent comparisons showed that it was placed into the genus Ruegeria with 97.4 % similarity to Ruegeria lacuscaerulensis ITI-1157(T), and a lower sequence similarity to all other species of the genus Ruegeria. Reconstruction of phylogenetic trees indicated that strain CC-GIMAT-2(T) clustered within the genus Ruegeria. Robust tree topology for the genus Ruegeria including the new strain was only obtained by including all Rhodobacteraceae type strains but not if the analysis was limited to few selected taxa. The quinone system contained exclusively ubiquinone Q-10 and the fatty acid profile consisted mainly of C18 : 1ω7c, 11-methyl C18 : 1ω7c and C12 : 0 3-OH. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified aminolipid. Other lipids were detected in moderate to minor amounts. The characteristic feature of the polyamine pattern was the predominant triamine spermidine. On the basis of the 16S rRNA gene sequence analysis and of the chemotaxonomic and physiological data, strain CC-GIMAT-2(T) represents a novel species of the genus Ruegeria, for which the name Ruegeria intermedia sp. nov. is proposed. The type strain is CC-GIMAT-2(T) ( = CCUG 59209(T) = LMG 25539(T) = CCM 7758(T)).
