Sulphur cycle & microbes

  1. 1. Sulphur cycle & microbes b.stev
  2. 4. What MICROBES do is perform important chemical reactions The result from this process is a product that is expelled THEN
  3. 6. FLOWS into rivers / swamps / lakes ALSO: the activity of volcanoes & volcanic soil SULPHUR is the 10 th most abundant element & is within the rocks and soils of the world (Wikipedia, 2008)
  4. 7. (Microbiologyprocedure, 2008)
  5. 8. the SULPHUR is absorbed for use a PRODUCT excreted in another form What Happens?
  6. 9. years of RESEARCH has been performed on nutrient cycles & how this occurs <ul><li>the next picture : shows the cycle of sulphur </li></ul><ul><li>observe what occurs in the soil & ocean </li></ul><ul><li>microbes are essential within this process </li></ul>
  7. 11. LET’S look at some of the equations that occur: hydrogen sulphide sulphur
  8. 12. Desulphovibrio Desulphomonas sulphate hydrogen sulphide
  9. 13. Chromatium Chlorobium hydrogen sulphide sulphur (Wikipedia, 2008)
