Bacterial Responses to Extreme Temperatures and Pressures and to Heavy Organic Loading
Abstract
The goals of this project centered around two areas of research: (1) the study of hyperthermophilic archaebacteria from submarine hydrothermnal vents on the East Pacific Rise; and (2) the study of physiologically diverse microbial populations associated with a whale carcass partially buried in sediments of the Santa Catalina Basin. Specific objectives included the following: (1) Completion of analyses of all geochemical, biochemical and microbiological measurements made on smoker fluid samples; (2) Further characterization of DNA from smoker samples and selected isolates to assess phylogenetic origin; (3) Determination of upper temperature and pressure limits for growth and survival of hyperthermophilic archaebacteria; (4) Tests for production of thermostable extra-cellular enzymes at extreme conditions; (5) Physiological types of bacterial-invertebrate symbioses in the deep sea directly reflect available energy sources; and (6) Deep-sea conditions of low temperature and elevated pressure do not limit bacterial responses to intense organic loading.
