Physiological and Phylogenetic Study of Microbes from Geochemically and211 Hydrogeologically Diverse Subsurface Environments

摘要

This project focuses on phylogenetic characterization of selected groups of211u001emicroorganisms that have been isolated from deep terrestrial subsurface 211u001eenvironments. Phylogenetic characterization is accomplished by analysis of 16S 211u001eribosomal RNA gene (rDNA) nucleotide base sequences and (in some cases) by 211u001erestriction endonuclease analysis. This work addresses the primary objectives of 211u001ethe GEMHEX project in the Transitional Phase of the program and several priority 211u001eresearch questions in the Origins Research Implementation Plan for the Deep 211u001eMicrobiology Subprogram.
