Visualization of Excitonic Structure in the Fenna-Matthews-OlsonPhotosynthetic Complex by Polarization-Dependent Two-DimensionalElectronic Spectroscopy

Description: Photosynthetic light-harvesting proceeds by the collection and highly efficient transfer of energy through a network of pigment-protein complexes. Inter-chromophore electronic couplings and interactions between pigments and the surrounding protein determine energy levels of excitonic states and dictate the mechanism of energy flow. The excitonic structure (orientation of excitonic transition dipoles) of pigment-protein complexes is generally deduced indirectly from x-ray crystallography in comb… more

[Tools for determining health of phytoplankton cells]

Description: The primary purpose of the proposed research is to develop molecular tools for determining the health of marine phytoplankton on an individual cell basis. Since the definition of healthy in phytoplankton cells is elusive, we propose to develop markers for several different metabolic processes indicative of physiological state: photosynthetic activity, esterase activity, membrane permeability, and mitochondrial activity. One underlying motivation is to develop methods which will allow us to eval… more

Water potential and starvation stress in deep subsurface microorganisms

Description: Nine intact core samples, collected aseptically from depths of 10--436 m near the Savannah River Plant in South Carolina, were tested for water potential, microbial numbers, and microbial activity. Although all samples were collected from below the water table, two samples (a Pee Dee clay from 238 m and a Middendorf clay from 324 m) showed unsaturated conditions ({minus}2.7 and {minus}2.1 MPa, respectively). Both of these samples had very low numbers of culturable cells, low microbial biomass (… more

Environmental Parameters Controlling Microbial Activities in Terrestrial Subsurface Environments. Technical Completion Report.

Description: This project was begun in July 1988 as part of Phase I of the Deep Microbiology Subprogram. At this time, the Subprogram was preparing for sampling near the Savannah River Site (SRS) from what was being termed the ``Investigator`s Hole.`` This was the fourth hole drilled for sampling in the coastal plain sediments at a site near the SRS. Since there was a possibility of sampling from the saline Triassic basin in the deeper regions in this fourth hole, there was particular interest in quantifyin… more

Quarterly Progress Report (April 1 to June 30, 1950)

Description: This is the second of a series of Quarterly Progress Reports. While most of the departments have summarized their work or used a form comparable to abstracts, the Chemistry Department has given both abstracts and complete reports on its work. The major part of the progress in the Reactor Science and Engineering Department is being presented simultaneously in a separate classified report. There are reports from the following departments: (1) physics department; (2) instrumentation and health phy… more

Field Manual for Phocid Necropsies (Specifically Monachus schauinslandi)

Description: From introduction: This necropsy manual is a guide for students and technicians in the examination of dead phocids, specifically the Hawaiian monk seal. With this manual, the person performing the necropsy should be able to conduct a gross examination of a monk seal and collect the necessary tissues for microscopic pathology and toxicological studies. The necropsy instructions are based on the assumption that the seal's carcass is very fresh and time is not a limiting factor.

Penetration of the Gut Wall by Intestinal Bacteria After X-Irradiation. Progress Report June 1, 1955 to January 31, 1956

Description: Factors affecting bacterial invasion from the intestinal tract in x-irradiated mice were investigated. P. morganii was administered in the drinking water on the seventh day following exposure to 600 r total-body x-irradiation. Mortality increased from about 40% following irradiation alone to about 62% after radiation and bacterial challenge together. No effect on mortality was produced by immunization with P. morganii prior to irradiation or injection of spleen homogenates from normal mice shor… more

Microbial dissolution of silicate materials. Final report

Description: The objective of this research was to better understand the role of selected thermophilic bacteria in the colonization and dissolution of silicate minerals, with potential applications to the HDR Project. The demonstration of enhanced dissolution from microbial effects is critically dependent on providing a mineral bait within a media deficient in the critical nutrient found in the mineral (e.g., Fe). Reproducible experimental conditions in batch experiments require agitation to expose mineral … more

Over production of lignocellulosic enzymes of Coriolus versicolor by genetic engineering methodology. Final report

Description: The project seeks to understand the biological and chemical processes involved in the secretion of the enzyme polyphenol oxidase (PPO) by the hyphae, the basic unit of the filamentous fungus Coriolus versicolor. These studies are made to determine rational strategies for enhanced secretion of PPO, both with the use of recombinant DNA techniques and without. This effort focuses on recombinant DNA techniques to enhance enzyme production. The major thrust of this project was two-fold: to mass prod… more
