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...

Factors that influence sulfide production in an estuarine environment

Creator:: Peterson, Paul Edward
Abstract:: Core samples from five sites in the Yaquina and Coos Estuary were assayed for vertical distribution of total sulfides, percent volatile solids, redox potential, particle size, total aerobic and sulfate reducing bacteria. Higher total sulfide levels were found at sites having more than four percent volatile solids, redox potential below...

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...

Development of a Bioluminescent Sensor of Isothiocyanates through Genetic Modification of Pseudomonas fluorescens and Validation on Crude Plant Materials

Creator:: Hogaboam, Octavia L.
Abstract:: Isothiocyanates (ITCs) are produced by roots in a variety of agricultural plants, such as those within the Brassicaceae family. ITCs act as fumigants, and are used to control microbial plant pathogens by adding brassica-origin seed meal to soil prior to replanting. However, there is suggestion that the presence of residual...

A physiological approach to a rapid method for identifying C. botulinum

Creator:: Dyer, John Kaye
Abstract:: Disc gel electrophoresis of the vegatative cell -free extracts ofstrains of Clostridium botulinum types A, B, C, E, and F and therelated nontoxic group showed limited value as a means for identifyingthese closely related microorganisms, since separation,though not consistent in all cases, could only be based on the numberof protein...

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...

Yeast extractives in the nutrition of San Francisco sourdough bacteria (Lactobacillus sanfrancisco)

Creator:: Berg, Ronald Wayne
Abstract:: A laboratory-prepared hot-water extract of yeast is required for vigorous growth of San Francisco sourdough bacteria (Lactobacillus sanfrancisco) in pure culture. This requirement was examined with the goal of determining what is unique about fresh yeast extractives (commercial extractives exhibit much lower growth promoting activity), and which components of fresh...
