Salana multivorans gen. nov., sp nov., a novel actinobacterium isolated from an anaerobic bioreactor and capable of selenate reduction

Three facultatively anaerobic, Gram-positive bacteria, strains Se-3111(T), Se-13111 and Se-1311A, were isolated from an anaerobic, dechlorinating bior eactor culture enriched from sediment of the River Saale in Germany. All st rains were isolated from the dechlorinating mixed culture through their abi lity to reduce selenate anaerobically to elemental selenium. Ail three stra ins shared identical 16S rDNA sequences and phylogenetic analysis revealed that strain Se-3111(T) forms a novel taxon within the suborder Micrococcine ae of the class Actinobacteria, related most closely to Beutenbergia cavern ae. On the basis of genotypic, chemotaxonomic and physiological characteris tics, it is proposed that the novel strains Se-3111(T), Se-13111 and Se-131 1A be classified in a new genus as Salana multivorans gen. nov., sp. nov. T he type strain of the novel species is Se-3111(T) (= DSM 13521(T) = NRRL B- 24118(T)).
