Abstract
A novel Gram-negative and rod-shaped bacterial strain, de-signated as 16F6ET, was isolated from a water sample. Cells were yellowish in color and catalase- and oxidase-positive. The strain grew at 10–37°C (optimum at 25°C) but not at 4 and 42°C, and pH 5–7 (optimum at pH 7). It showed mod-erate resistance to gamma-ray irradiation. Comparative phy-logenetic analysis showed that strain 16F6ET belonged to the family Cytophagaceae of the class Cytophagia. Furthermore, this isolate showed relatively low 16S rRNA gene sequence similarities (90.7–93.1%) to the members of the genus Spiro-soma. The major fatty acids were summed feature 3 (C16:1 ω7c/C16:1 ω6c), C16:1 ω5c, C16:0 N alcohol, and C16:0. The polar lipid profile indicated presence of phosphatidylethanolamine, unknown aminophospholipids, an unknown amino lipid, unknown phospholipids, and unknown polar lipids. The pre-dominant isoprenoid quinone was MK-7. The genomic DNA G+C content of strain 16F6ET was 56.5 mol%. Phenotypic, phylogenetic, and chemotaxonomic properties indicated that isolate 16F6ET represents a novel species within the genus Spirosoma, for which the name Spirosoma luteolum sp. nov. is proposed. The type strain is 16F6ET (=KCTC 52199T =JCM 31411T).
