A microscopic and analytical study of extreme thermophile bacteria in simulated environments compared to organic matter in early Earth hydrothermal systems. The study will examine microbial cells and organic residues of cultured thermophilic archaea from simulated extreme environments in terms of temperature, pressure and mineral concentrations. These will be compared, applying observational and geochemical techniques to organic material in geologically earliest ecosystems. A novel approach will ....A microscopic and analytical study of extreme thermophile bacteria in simulated environments compared to organic matter in early Earth hydrothermal systems. The study will examine microbial cells and organic residues of cultured thermophilic archaea from simulated extreme environments in terms of temperature, pressure and mineral concentrations. These will be compared, applying observational and geochemical techniques to organic material in geologically earliest ecosystems. A novel approach will be adopted, of 'backtracking' changes occurring to cultured microbial cells towards their breakdown and disintegration (in contrast to the more common approach of simulating synthesis of organic compounds as a starting point towards structured functioning organisms), and their viability limits. The results of the study will be tested within the currently available theoretical models for the origin of life.Read moreRead less

Summary
High resolution liquid chromatography mass spectrometry (Orbitrap) for analyses of polar compounds in biomass, petroleum, potable and reclaimed water. Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources. Chemical and biological characterisation of aquatic and terrestrial environments is paramount to assessing and responding to these threats, as well as assisting natural resource utilisation. The high structural pola ....High resolution liquid chromatography mass spectrometry (Orbitrap) for analyses of polar compounds in biomass, petroleum, potable and reclaimed water. Climate change and human impact can harm sensitive ecosystems, significantly threatening Australian biodiversity and water resources. Chemical and biological characterisation of aquatic and terrestrial environments is paramount to assessing and responding to these threats, as well as assisting natural resource utilisation. The high structural polarity of many environmentally occurring organics from biological, petroleum and anthropogenic sources, unamenable to gas chromatographic resolution, can now be accommodated by the advanced organic analytical technology sought in this proposal. This project will enable scholars and young professionals to be skilled in state-of-the-art technology, and prepare quality scientists, ready for employment.Read moreRead less
