title: [Sulfur metabolism enzymes in thermoacidophilus bacteria Sulfobacillus sibiricus].
abstract: Sulfur oxygenase, sulfite oxidase, adenylyl sulfate reductase, rhodanase, sulfur:Fe(III) oxidoreductase, and sulfite:Fe(III) oxidoreductase were found in cells of aerobic thermoacidophilic bacteria Sulfobacillus sibiricus strains N1 and SSO. Enzyme activity was revealed in cells grown on the medium with elemental sulfur or in the presence of various sulfide elements and concentrates of sulfide ores. The activity of sulfur-metabolizing enzymes depended little on the degree of aeration during bacterial growth.
