Title: Microbial Gene Research
1 List of Projects on Microbial Diversity Suitable
for Metagenomics
Australia is one of 12 megadiverse
countries Australia has large numbers of extreme
habitats Developing a microbial gene repository
of extremophilic microbes from Australian
ecosystems is a logical starting point

3The Great Artesian Basin (GAB) is a unique deep
subsurface thermal non-volcanic aquifer Worlds
largest underground water reserve (1.7 x 106 km2
8.7 x 1012 m3) 5000 free-flowing bore wells
have been drilled thro 4 sequential interbeded
sedimentary bases of different geological ages
distinct water chemistry. Natural discharge via
mound springs (basin edges)

4- GAB is a hot bed for microbial colonisation
adaptation of new types of microbes - Heated by the earths hot core due to the deep
nature of the aquifer- rate of 1oC/30 m depth - gradient to ambient along drain runoff channels
- Aquifer age 2 million yrs (water) but the
sedimentary bases are up to 400 million old - pH neutral to 10
