Sulphur cycle & microbes

Sulphur cycle & microbes b.stev

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

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)

(Microbiologyprocedure, 2008)

the SULPHUR is absorbed for use a PRODUCT excreted in another form What Happens?

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

LET’S look at some of the equations that occur: hydrogen sulphide sulphur

Desulphovibrio Desulphomonas sulphate hydrogen sulphide

Chromatium Chlorobium hydrogen sulphide sulphur (Wikipedia, 2008)
