Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Differential agar media for the identification of the Salmonella and Arizona groups of Enterobacteriaceae

Creator:: Stroup, John Raymond
Abstract:: Twelve differential agars have been studied in the development of media to presumptively identify the Salmonella Subgenera I-IV. Medium No. 7B/A (or Medium No. 7-H₂S Strip) combined the malonate, dulcitol, lysine decarboxylase and hydrogen sulfide reactions in one tube. It was designed to be used at the TSI stage of...

Serological detection of staphylococcal enterotoxin A in culture supernatants

Creator:: Nkanga, Enefiok James
Abstract:: A method has been presented for the observation of a large number of enterotoxin A producers. Production of a relatively concentrated toxin is achieved by the sac culture method. Further concentration, if needed, is carried out by PM-10 membrane ultrafiltration after centrifugation. The work is further improved by trypsinization of...

A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

Creator:: Ley, Ronald Douglas
Abstract:: Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

A comparative study of Clostridium botulinum strains using differential egg yolk media

Creator:: Stiebrs, Anita
Abstract:: The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification of Clostridium botulinum type E strains, and to develop a more reliable method and media for the differentiation of this organism based on the "pearly...

Identification of volatiles from a swine center using porous polymers and cold traps

Creator:: Kelly, Michael David
Abstract:: This project was initiated to find a practical way of identifying the volatiles and monitoring their relative concentrations. Special attention was given to the identification of the organic acids. Volatile compounds produced in a swine confinement building were trapped by porous polymers, Porapak Ω and Tenax GC, and identified by...

Factors affecting slime accumulation in fiberboard mill process water

Creator:: Minelli, Michael Philip
Abstract:: The objectives for this study were to determine the causes of slime formation in activated sludge treatment and to recommend possible control measures. The primary problem was a seasonal filamentous bulking which was caused by the mold, Geotrichum candidum. During the winter, mycelial fibers appeared and formed a free floating...

Improved detection methods and physiological studies of staphylococcal enterotoxin

Creator:: Kimble, Charles E.
Abstract:: The purpose of this study was to develop means to facilitate the detection of staphylococcal enterotoxin and to elucidate factors that influence enterotoxin formation. It was found that semipurification flat-gel electrophoresis in a water-cooled apparatus was more efficient than CM-cellulose and Sephadex column chromatography currently used to separate toxin from...

Photooxidative degradation of annual rye-grass straw to substrates enhancing rhodotorula mucilaginosa growth

Creator:: Park, Jerry Eugene
Abstract:: Annual ryegrass (Lolium multiflorum) is a major seed crop in the Willamette Valley of Oregon. Persistent crop diseases have necessitated annual field burning to protect future crops. This practice, while very effective for disease eradication, produces large quantities of air polluting smoke in the valley and a general wastage of...
