Note: Desulfovibrio aespoeensis sp. nov., a mesophilic sulfate-reducing bacterium from deep groundwater at aspo hard rock laboratory, Sweden

A sulfate-reducing bacterium, strain Aspo-2, was isolated from granitic groundwater sampled at a depth of 600 m. This and other strains of SRB frequently occur in the deep granitic rock aquifers studied. On the basis of its morphological, physiological and genotypical properties, and its unique habitat, we propose strain Aspo-2 as a new species of the genus Desulfovibrio, Desulfovibrio aespoeensis (DSM 10631^T).
