Transcript

  • 1. Sulphur cycle & microbes b.stev
  • 2.  
  • 3.  
  • 4. What MICROBES do is perform important chemical reactions The result from this process is a product that is expelled THEN
  • 5.  
  • 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)
  • 7. (Microbiologyprocedure, 2008)
  • 8. the SULPHUR is absorbed for use a PRODUCT excreted in another form What Happens?
  • 9. years of RESEARCH has been performed on nutrient cycles & how this occurs
    • the next picture : shows the cycle of sulphur
    • observe what occurs in the soil & ocean
    • microbes are essential within this process
  • 10.  
  • 11. LET’S look at some of the equations that occur: hydrogen sulphide sulphur
  • 12. Desulphovibrio Desulphomonas sulphate hydrogen sulphide
  • 13. Chromatium Chlorobium hydrogen sulphide sulphur (Wikipedia, 2008)
  • 14.
