In the introduction, briefly describe the habitat that is the topic of this page. Introduce the habitat, its ecological significance, and the importance of microorganisms in this environment. (What processes do they carry out? What functions do they perform?)
Microbes have found a way to exist in every corner of the planet, and humans have found ways to utilize their incredible diversity for thousands of years. From fermenting cheese and wine, to the production of pharmaceuticals, microbes have been utilized for a myriad of reasons. It was not until the late 1920's however, that scientists thought to look deep within the body of our earth itself for a new source of potential biodiversity.
Deep subsurface microbes first came into question when the American geologist Edson S. Bastin questioned why samples of water extracted from oil fields contained hydrogen sulfide and bicarbonates. Armed with the knowledge that certain species of bacteria can derive energy from reducing sulfur compounds in the absence of oxygen, he concluded that there must be populations of these bacteria living in the underground oil reserves, degrading the organic components of oil as a carbon source, and reducing sulfur compounds for energy. By 1926, Bastin and his colleague, Frank E. Greer has cultured sulfur reducing bacteria from samples taken from the groundwater of an oil deposit several hundred meters below the surface. Bastin and Greer's initial deduction was that the bacteria were the ancestors of those buried up to 300 million years ago when the organic materials constituting the oil deposit were buried.
Describe the physical and chemical characteristics of the environment, using as many sections/subsections as you require. If it is appropriate, you can divide the physical and chemical attributes of the environment into separate sections. Look at other topics available in MicrobeWiki. Which involve processes similar to yours? Create links where relevant.
What kind of microbes do we typically find in this environment? Or associated with important processes in this environment? Describe key groups of microbes that we find in this environment, and any special adaptations they may have evolved to survive in this environment. List examples of specific microbes that represent key groups or are associated with important processes found in this environment. Link to other MicrobeWiki pages where possible.
Are there important biological interactions that are important in this environment? Do these interactions influence microbial populations and their activities? How do these interactions influence other organisms? Describe biological interactions that might take place in this environment, using as many sections/subsections as you require. Look at other topics available in MicrobeWiki. Create links where relevant.
What microbial processes define this environment? Describe microbial processes that are important in this habitat, adding sections/subsections as needed. Look at other topics in MicrobeWiki. Are some of these processes already described? Create links where relevant.
