ABSTRACT
A Gram-stain-negative, rod-shaped, amylolytic bacterial strain, designated as bsSlp3-1T, was isolated from the Slepian water system, a freshwater reservoir. Strain bsSlp3-1T was found to be aerobic, oxidase-positive and catalase-negative, grew at 5-37â°C (optimum, 28â°C), pH 5.0-9.5 (optimum, pH 7.0) and low NaCl concentration (up to 1.0â%). Comparative analysis of 16S rRNA gene sequence similarity revealed that strain bsSlp3-1T clustered with Roseateles species and is closely related to Roseateles depolymerans KCTC 42856T (98.7â%) and Roseateles terrae CCUG 52222T (98.6â%). Whole-genome comparisons using average nucleotide identity and digital DNA-DNA hybridization values suggested that strain bsSlp3-1T represents a novel species within the genus Roseateles and is most closely related to Roseateles aquatilis CCUG 48205T (81.2 and 25.6â%, respectively). The genome of strain bsSlp3-1T consisted of a single circular chromosome with size 6â289â366 bp and DNA G+C content of 66.8 mol%. The predominant cellular fatty acids of bsSlp3-1T were cis-9-hexadecanoic and hexadecenoic acids. According to the data obtained in this work, strain bsSlp3-1T represents a novel Roseateles species for which the name Roseateles amylovorans sp. nov. is proposed. The type strain is bsSlp3-1T (=BIM B-1768T=NBIMCC 9098T=VKM B-3671T).
