  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 Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS)

  2. Australian Ecosystems • 1. Insect Guts- • 2. Water- • Dam • Waste • 3. Cultural Foods- • 4. Extreme- • Subsurface • Oil • Artesian • Hypersaline Microbial Diversity Related Projects • 1. Rainforest insect microbiology • Anaerobic aromatic metabolism • 2. Cyanobacterial blooming in dam water • 3. Industrial wastewater (wheat) microbiology • 4. Microbial enhanced oil recovery & oil souring • 5. Microbiology of Hypersaline environments • 6. Microbiology of fermented foods of Asia- • Pacific • 7. Microbiology of the Great Artesian Basin of • Australia (GAB) • Microbial mats • Microbial corrosion of bore casing Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS)

  3. The 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)  Brisbane Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS)

  4. GAB is a “hot bed” for microbial colonisation adaptation of new types of microbes: • Heated by the earth’s hot core due to the deep nature of the aquifer- rate of 1oC/30 m depth • < 95 oC at bore source; forms a temperature 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 Microbial Gene Research & Resources Facility (MGRRF) Institute for Molecular & Cellular Therapies (IMCT) Biomolecular & Biomedical Sciences (BBS)
