"Until recently, much of our understanding of microorganisms in the subsurface was largely a matter of speculation. Recent advances in technology and methodology have enabled the discovery and study of microorganisms in deep subsurface environments. Researchers are now able to explore relationships between microbial physiology, taxonomy, and genetics, and the environment of these microorganisms, including geochemical, geological, and hydrological properties. Subsurface Microbiology and Biogeochemistry is a necessary learning tool that focuses on the integration of microbiology and the geosciences. The subsurface environment provides numerous niches for microorganisms and this book presents research in subsurface microbiology in addition to providing an understanding of the broad range and diversity of the previously "hidden" subterranean organisms. Contributing chapters from experts in their respective disciplines discuss the results of deep subsurface microbiology studies and enlighten the reader as to how the subsurface environment has grown to represent a true frontier for microbiological research. Subsurface Microbiology and Biogeochemistry reviews an important topic that is at the vanguard of subsurface environment studies with implications on the search for life on other planets. The discovery of subsurface microorganisms creates a multitude of opportunities for microbiologists and engineers in academia and biotechnology, with this book at the forefront of essential reading."--Publisher's website.
