Acidovorax bellezanensis sp. nov., a novel bacterium from uranium mill tailings repository sites with selenium bioremediation capabilities.

ABSTRACT: A Gram-stain-negative bacterial strain designated Be4^T, belonging to the genus Acidovorax, was isolated from mining porewaters sampled in uranium mill tailings repository sites, located in Bellezane, near Bessines-sur-Gartempe (Limousin, France). Cells were facultative anaerobic, rod-shaped, non-endospore-forming and motile with flagella. The mean cell size was 1.25-1.31 μm long and 0.70-0.73 μm wide. Colonies were light yellow, opaque, circular, convex with smooth margins, and 1-2 mm in diameter. Growth occurs at 4-37 °C and between pH 5.5-9.0. It differed from its phylogenetically related strains by phenotypic and physiological characteristics such as growth at 4 °C, presence of acid phosphatase, naphthol-AS-BI-phosphohydrolase and β-glucosidase enzymatic activities, an
