sulphur cycle, sulphur cycle in soil, microbes in the sulphur cycle, where sulphur is derived, where sulphur comes from, Beggiatoa, Thiobacillus, Desulphovibrio, Desulphomonas, Chromatium,Chlorobium, equations of the sulphur cycle

1. Sulphur cycle & microbes b.stev

4. What MICROBES do is perform important chemical reactions The result from this process is a product that is expelled THEN

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?

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)
