摘要

Sulfate-reducing bacteria play a major role in organic carbon degradation in many anaerobic environments and may cause environmental problems due the production of toxic sulfide. The activity of SRB cause severe economic problems in the oil industryby souring of oil and gas reservoirs and by enhancing corrosion of equipment. However, the sulfidogenic activity of SRB may also be benefical, e.g. in metal recovery processes where biogenic sulfide is used to precipitate highlytoxic metal ions. Recent research has demonstrated that SRB are physiologically much more diverse than hitherto belived. These findings have important implications for the activity and survival of SRB in natural environments and for potential biotechnological applications of this group of bacteria. The presentation will address the physiological diversity of SRB, their tolerance towards oxygen and problems of enumeration of SRB in different environments.
