Three facultatively anaerobic, Gram-positive bacteria, strains Se-3111T, Se-13111 and Se-1311A, were isolated from an anaerobic, dechlorinating bioreactor culture enriched from sediment of the River Saale in Germany. All strains were isolated from the dechlorinating mixed culture through their ability to reduce selenate anaerobically to elemental selenium. All three strains shared identical 16S rDNA sequences and phylogenetic analysis revealed that strain Se-3111T forms a novel taxon within the suborder Micrococcineae of the class Actinobacteria, related most closely to Beutenbergia cavernae. On the basis of genotypic, chemotaxonomic and physiological characteristics, it is proposed that the novel strains Se-3111T, Se-13111 and Se-1311A be classified in a new genus as Salana multivorans gen. nov., sp. nov. The type strain of the novel species is Se-3111T (= DSM 13521T = NRRL B-24118T).
