sp. nov., a moderate thermophile isolated from a coastal hot spring Free

Abstract

A yellow-pigmented, Gram-staining-negative, aerobic, non-motile, moderately thermophilic, rod-shaped bacterium, designated strain CC-HSB-11, was isolated from a coastal hot spring of Green Island (Lutao), located off Taituang, Taiwan. 16S rRNA gene sequence analysis demonstrated that it shared <94.4 % sequence similarity with species. Menaquinone with six isoprene units (MK-6) was the major respiratory quinone and iso-C, iso-C G, iso-C 3-OH, iso-C 3-OH, iso-C 3-OH and summed feature 3 (comprising iso-C 2-OH and/or C 7/) were the predominant fatty acids. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Six unidentified phospholipids and glycolipids also occurred as minor components. The DNA G+C content of strain CC-HSB-11 was 46.4±1 mol%. On the basis of 16S rRNA gene sequence similarities with other species and differentiating fatty acid compositions and other phenotypic data, strain CC-HSB-11 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is CC-HSB-11 (=BCRC 17850 =KCTC 22339).
