Microbiology of Subsurface Environments. Preliminary Statement of Research Goals and Abstracts of Current Research

摘要

This document contains information concerning a fundamental research program in deep subsurface microbiology. A two phased program is planned. Phase I (FY86-FY87) is exploratory research phase that will focus on the presence, abundance, and diversity of indigenous microorganisms, community structure, and on the hydrogeologic, geochemical, and physical interactions that control microbial presence and activity. Preliminary information on the biodegradation capabilities and functioning of these organisms may also be developed. Phase II (FY88-FY92) will concentrate on exploiting some scientific advances and research opportunities identified in Phase I, largely by extended (36 to 48 month) research investigations. The functioning of microorganisms at depth, biotransformation processes, and community growth rates are among the areas that may be investigated. Phase II will provide information that leads to investigating microbial processes that contribute to the mitigation of subsurface contamination, to determining environmental stimulation that will contribute to mitigation and (in time) to evaluation of the impact of bioengineered organisms on subsurface ecosystems.
