The natural products chemistry of the red algae Ptilota filicina and Laurencia obtusa

Creator:: Lopez, Albert
Abstract:: The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...

Biochemical studies on the mosquitocidal delta endotoxin of Bacillus thuringiensis subsp. israelensis

Creator:: Pollock, Martin L.
Abstract:: The cytolytic properties of the mosquitocidal 25 Kd protein deltaendotoxin of Bacillus thuringiensis subsp. israelensis (Bti) was studied using the human erythrocyte as a target cell. Both a fixedtime and a kinetic hemolytic bioassay were developed in order to screen a variety of treatments for their influence on the toxinerythrocyte...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Community composition and activities of denitrifying bacteria in soils

Creator:: Rich, Jeremy J.
Abstract:: Few studies have directly compared denitrifying community composition and activities in soils by coupling molecular-genetic techniques and traditional measures of denitnfication. I investigated communities of denitrifying bacteria from adjacent meadow and forest soils in the Cascade Mountains, Oregon. A key gene in the denitrification pathway, N₂O reductase (nosZ), served as...

Examination of Immobilized TiO2 Nanoparticle Photocatalytic Treatment of Propylene Glycol with Concentrated Solar Energy

Creator:: Hammervold, Meredith
Abstract:: Airports are required by the Federal Aviation Administration to perform deicing of aircraft pavement during icy conditions. Until recently, there were no discharge controls in place and deicing fluid contaminated nearby water bodies from storm water runoff. EPA regulations now require airports to collect the deicing fluid and meet discharge...

Volatile Organic Compound Production in Synechococcus WH8102

Creator:: Ocel, Duncan R.
Abstract:: High-resolution mass spectrometry was used to measure a range of volatile organic compounds (VOCs) in real time as they were produced by the ubiquitous marine cyanobacterium Synechococcus WH8102 during a 24-hour light/dark cycle. Ethenone, acetaldehyde, ethanol, isoprene, acetic acid, dimethyl sulfide (DMS), acetone, phenol, and several as-yet unidentified compounds were...

Microcosm studies of bioaugmentation with a butane-utilizing mixed culture : microbial community structure and 1,1-DCE cometabolism

Creator:: Lim, Hee Kyung
Abstract:: The 1,1-dichloroethene (1,1-DCE) cometabolic transformation abilities of indigenous and bioaugmented microorganisms were compared in microcosms constructed with groundwater and aquifer solids from the Moffett Field site, CA. Microbial community structure in the microcosms and possible community shifts due to 1,1-DCE transformation stress was evaluated by terminal restriction fragment length polymorphism...

Design and implementation of a physical model for Keystone Harbor, WA

Creator:: Richmond, J. Brady
Abstract:: Strong tidal currents experienced at Keystone Harbor, WA, have caused navigational hazards and disrupted ferry service in the area. This thesis presents details of the design, construction and implementation of a large scale physical model of Keystone Harbor used to evaluate the effectiveness of proposed jetty design alternatives to improve...

The effects of stand thinning on soil erosion rates at Jim's Creek in the Willamette National Forest, Oregon

Creator:: McFadden, Andrew K.
Abstract:: Surface sediment transport is an important geomorphic process which can be significantly altered by management activities in forested ecosystems. Disturbance of the soil surface may result in increased sediment delivery to fish bearing streams and degradation of soil structure. Selective thinning and low impact yarding techniques were utilized in an...
