	Geomicrobiology - Wikipedia, the free encyclopedia
		Geomicrobiology is a science that combines geology and microbiology, and studies the interaction of microscopic organisms with their inorganic environment, such as in sedimentary rocks.
		Another field of study in geomicrobiology is the study of extremophile organisms, the microorganisms that thrive in environments normally considered hostile.
		An application of geomicrobiology is bioleaching, the use of microbes to extract metals from mine waste.

	Research
		In the geomicrobiology group, research is directed toward understanding how interconnected inorganic and biologically-mediated processes shape the geochemistry and mineralogy of the Earth's surface.
		Much of our work centers on the ways in which microorganisms impact the form and distribution of metals in the environment.
		Because microbial activity often results in the formation of minerals with sizes in the few nanometer diameter range, a significant research focus in our group involves study of the nanoparticles.

		The geomicrobiology course is aimed at both cavers and students who are interested in learning about the microorganisms that reside within caves; students do not need to have a background in microbiology, however a significant amount of reading will be required for students taking the course for college credit.
		Microscopic organisms were the first life to evolve on our planet almost 4 billion years ago, shaping the biosphere and global environment in which we live today.
		Geomicrobiology is the study of the geochemical interactions between microorganisms and Earth materials, combining the techniques of helping students understand the principles of geomicrobiology, including microbial metabolism, ecology and geochemistry, with an emphasis on cave formation and biogeospelogenesis.

	TINY STARS ON THE PLANET MARS: WHERE GEOMICROBIOLOGY IS LEADING THE SEARCH FOR EXTRATERRESTRIAL LIFE
		Geomicrobiology has exploded onto the scene over the past several decades splashing across biology, mineralogy, geochemistry, and other disciplines knitting them together to provide a more understandable picture of the biological/abiological interfaces where geomicrobes spend their time.
		Geomicrobiology has thus become a major player in a great Dress Rehearsal in our quest to detect the presence of extant or extinct extraterrestrial life.
		Thus, geomicrobiology is helping us to stretch our imaginations far enough to be prepared to recognize what we may find some day amongst the stars.

		Geomicrobiology is a science that combines geology and microbiology, and studies the interaction of microorganisms with their inorganic environments, such as in sedimentary rocks.
		Microorganisms are increasingly regarded as important contributors of the Geosphere.They are active as geologic agents, since the earliest stages of life on Earth, by contributing in minerals and rocks formation, and by inducing sedimentary structures in ancient environments.
		Here life is mostly or exclusively represented by microbes and the understanding of how they grow, interact with physical processes and are preserved in rocks may help for search of present and past extraterrestrial life.

		Geomicrobiology is the study of microbial interactions with earth materials: soils, sediments, solutes, atmospheric gases, minerals, and rocks.
		Geomicrobiologists explore how microorganisms shape earth's geochemistry and environment in the present and over geologic time scales, making use of techniques and ideas drawn from many areas of chemistry, geology, biology and ecology.
		There is significant cross-fertilization between geomicrobiology and fields such as astrobiology (the study of life in the universe), the origin of life, paleobiology, nanoscience, soil science, limnology, oceanography, global climate change, medical microbiology, and environmental engineering.

		Research at the interface between geochemistry and microbiology is providing insight into the earliest stages of life on Earth and helping tackle significant environmental issues such as remediation of pollution at industrial and nuclear sites.
		The AACES Geomicrobiology program brings a wide range of analytical techniques to focus on the activity of microorganisms at mineral surfaces and other geological matrices.
		The research ranges from developing an understanding of the chemical, isotopic or mineralogic ‘signatures’ left behind by microorganisms in sediments and rocks to the ways in which microbial metabolic processes can be employed in the sub-surface environments to limit the mobility of heavy metal and radionuclide pollutants.

		The overarching theme of the work of this group is the characterization of mineral-water-organic matter reactions in surface and subsurface environments.
		As chemical reactions in these environments are often catalysed by microorganisms, we have developed a recent and expanding interest in geomicrobiology.
		Here, by combining the techniques of microbiology and molecular biology with physical, chemical and modelling approaches, we are focusing on the role microorganisms play or have played in key geological processes.

		The benefits of event plume opportunities to my studies of geomicrobial community dynamics in a chemically evolving hydrothermal plume include a well-constrained date of origin (t0), a precise real-time based time-line for subsequent sampling and experiments, and a relatively isolated, natural large volume deep-sea experimental habitat, analogous to surface water warm/cold core rings.

		The geological isolation of these deep subsurface microbial communities offers the potential to answer questions on the origin of life and its diversity as well as constraining the possibilities for life beneath the surface of Mars and other planetary bodies.
		In addition to the role of microorganisms in shaping the life forms on earth, the importance of microorganisms in the dissolution and formation of minerals is only now becoming recognized as geomicrobiology comes to the fore.
		In addition, opportunities to address biogeochemical and microbial transport in compromised but well-characterized deep fractured rock aquifers have been limited and have been restricted to geographically dispersed locations, markedly constraining the collaboration between disciplines critical to understanding complex interrelated phenomena.
