Sulfur cycle

With our Sulfur Cycle analysis, microbial conversion of sulfur compounds is determined in your sample. On request we can give you advice on stimulating, preventing or managing sulfer cycling micro-organisms for your specific situation.

Analysis essentials

  • To determine the potential for microbial conversion of sulfur compounds
  • To determine the spread of micro-organisms involved in the sulfur metabolism
  • To monitor the potential for microbial sulfur conversions in time (does it increase or decrease?)

Content of the package

The following microbial key parameters are detected and quantified with our Sulfur Cycle analysis:

  • A gene specific for sulfate reduction, sulfite reductase
  • A gene specific for sulfur oxidation, thiosulfate oxygenase
  • A gene specific for the sulfur cycle, adenylyl sulfite reductase

NB: many different types of bacteria are known which can metabolize sulfur compounds. However, we analyse the functional potential for bacterial sulfate reduction and oxidation instead of all species. This increases the reliability of the results, prevents unnecessary analyses and therefore higher costs.

Background information

Bacteria of the sulfur cycle, in particular sulfate reducing (SRB) and sulfide oxidizing bacteria (SOB) are of great importance from an industrial and environmental point of view. Production of H2S by SRB for instance causes severe processing and environmental problems for the petroleum industry by causing biocorrosion. However, when used in a bioreactor, SRB can be successfully applied for waste water treatment. Oxidation of sulfide and intermediary sulfur compounds by SOB are crucial for bioleaching and the removal of H2S from oil reservoirs.
