Introduction

The point of this template is to give you a general idea of the layout of your page. You are not completely restricted to this format, so feel free to try out different things. We'll give you feedback as you work on your pages. Make sure to copy the "code" of this page to your own page before editing.

Irina C

Describe briefly the process you will address and the significance of soil microorganisms in the process (what functions do they perform?).

Process - key points

Describe the process, using as many sections/subsections as you require. Look at the list of other topics. Which involve processes similar to yours? Create links where relevant.


Key Microorganisms within Geomicrobiology

Geomicrobiology included organisms that are concidered extremophiles. Extremophiles are microorganisms that live in areas considered too hostile for most. An example of an extremophile is anerobic sulfate reducing bacteria, which are know to live in hyper-saline lagoons in Brazil and Australia. It is believed these bacteria may be responsible for the formation of dolmite

Examples of Microorganisms

An example of extemophile organism is: anaerobic sulfate-reducing bacteria

Sulfate-reducing bacteria (SRB) comprise of several groups of bacteria that use sulfate as an oxidizing agent, reducing it to sulfide. Most sulfate-reducing bacteria can also use other oxidized sulfur compounds such as sulfite and thiosulfate, or elemental sulfur. This type of metabolism is called dissimilatory, since sulfur is not incorporated - assimilated - into any organic compounds. Sulfate-reducing bacteria have been considered as a possible way to deal with acid mine waters that are produced by other bacteria.

Current Research and Links

There is a very intresting site hosted by the Geomicrobiology & Environmental Microbiology Studies at Louisiana State University http://www.geol.lsu.edu/aengel/index.htm This site is filled with current research photos and informative discussions concerning the topic.
