Geomicrobiology: Molecular and Environmental PerspectiveThe interaction of microorganisms with geological activities results in processes influencing development of the Earths geo and biospheres. In assessing these microbial functions, scientists have explored short and longterm geological changes attributed to microorganisms and developed new approaches to evaluate the physiology of microbes including microbial interaction with the geological environment. As the field of geomicrobiology developed, it has
