Balkwill, D L

We propose to accomplish two major objectives: (1) We will continue to characterize the aerobic, chemoheterotrophic microorganisms in samples of subsurface materials obtained during the Transitional Phase of the Deep Microbiology program. (2) We will continue and significantly expand on ongoing pylogenetic study of subsurface microorganisms previously isolated. We will analyze data obtained in the context of chemical, physical, and other microbiological data (obtained by other investigators in the program) on each subsurface sample, in order to determine the extent of which the size, composition, metabolic capabilities, and phylogenetic traits of the subsurface microbial community vary among hydrogeologically and geochemically diverse environments, and identify the chemical and physical environmental factors that most strongly influence such variations. This research will result in significant new information on subsurface microbial ecology and help us to answer questions relevant to the potential role of microorganisms in the remediation of subsurface contaminants. 41 refs.
