Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...

Disposal of sandy pipeline dredge spoils by end dumping

Creator:: Pyles, Marvin Russell
Abstract:: Channel maintenance operations in the rivers and harbors of the United States annually require the disposal of over 320 million cubic meters of dredge spoils. As the availability of suitable land sites diminishes, open water disposal presents an attractive yet controversial alternative method. For open water disposal to be acceptable,...

A method of PCB metabolite determination in anaerobic freshwater sediments using a upflow anaerobic biofiltration process (ANBIOF)

Creator:: Low, Edmond J.
Abstract:: The biodegradation of five polychlorinated biphenyls (PCBs) by Hudson River and Silver Lake sediments was studied using gas chromatography with electron capture detection (GC/ECD) and gas chromatography with mass spectrometry (GC/MS) analyses. Methanogenic sediments from the Hudson River and Silver Lake were used to inoculate four anaerobic filter reactors. The...

Down-borehole permeable barrier reactor : primary substrate selection for aerobic dichlorophenol degradation

Creator:: Kaslik, Peter J.
Abstract:: In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary substrate for dichlorophenol cometabolism. Serum bottle tests comparing the effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed phenol to be the most effective followed by imitation vanilla flavoring,...

A manual for plate loading tests performed on rock

Creator:: Dodds, Donald J.
Abstract:: Plate loading tests in rock are deceptively simple tests to perform. Consequently, many varieties have been developed in the past 60 years. From each of the varieties various investigators have added their own developments and modifications, some good, and some not so good. The result has been a confusion of...

Engineering properties of Oregon and Washington coast range soils

Creator:: Alto, Jalmer V.
Abstract:: Landslides are frequent in the steep forested regions of the Oregon and Washington coastal mountain ranges. The need for forest products has resulted in increasing logging activity in these marginally stable areas. The occurrence of landslides has increased, which in turn has focused greater interest in slope stability management. Of...

Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

Creator:: Kao, Yeoung Ting
Abstract:: Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

Effects of substrate interactions, toxicity, and bacterial response during cometabolism of chlorinted solvents by nitrifying bacteria

Creator:: Ely, Roger L.
Abstract:: Cometabolic biodegradation processes, important for bioremediation of hazardous waste sites, are not well understood and have not been modeled thoroughly. Toxic effects and bacterial responses to toxicity may change intracellular enzyme levels, rendering traditional enzyme kinetics models inappropriate. This document presents a novel cometabolic enzyme kinetics model that incorporates enzyme...

Modeling hydraulic dredge spoil fate

Creator:: Tseng, Ying-chuan
Abstract:: Hydraulic dredging is and most certainly will remain a primary means of maintaining and improving ship channels and for land reclamation in near-shore water. The study of which this thesis describes a part is intended to develop a method of predetermining the immediate disposition of sand spoils from hydraulic dredging...
