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...

Bactericidal and physico-chemical properties of a lectin derived from spring chinook salmon (Oncorhynchus tshawytscha) Ova

Creator:: Banowetz, Gary Michael
Abstract:: Unfertilized ova from spring chinook salmon (Oncorhynchus tshawytscha) were examined for the presence of classical salmonid inmmunoglobulin. Immunodiffusion techniques in which rabbit anti-salmonid immunoglobulin was reacted against an ova homogenate and rabbit anti-ova homogenate was reacted against immune chinook serum failed to detect classical-type antibodies within these eggs. A lectin...

Effects of physiological state upon nitrosoguanidine-mediated allelic recombination in Saccharomyces cerevisiae

Creator:: Buettner, Michael John
Abstract:: Saccharomyces cerevisiae strain XS-380, a. heteroallelic diploid strain, carries six genetically analyzed loci on the left arm of chromosome VII. Nitrosoguanidine (NMG) at low concentrations was observed to cause allelic recombination (either mitotic recombination or gene conversion) of the heteroallelic loci with low lethality. The NMG-inducible heteroallelic system was used...

Certain aspects of the immunology and chemotherapy of bacterial kidney disease in juvenile coho salmon (Oncorhynchus kisutch)

Creator:: Banowetz, Gary Michael
Abstract:: The detection and antigenic nature of the causative Corynebacterium of bacterial kidney disease and chemotherapy of this disease in juvenile coho salmon (Oncorhynchus kisutch) were examined. Each of 207 yearling coho salmon collected from a population undergoing a severe epizootic of bacterial kidney disease were examined for the presence of...

The effects of commercial rhizobium inoculants on the establishment of Trifolium subterraneum in southwest Oregon soils

Creator:: Jenkins, Michael B.
Abstract:: Commercial inoculant products for subclover that are marketed in the Pacific Northwest were evaluated in field trials (supplemented by appropriate laboratory analysis) at four sites in southwest Oregon. The materials tested were Nitragin (Milwaukee, WI) and Northrup-King (Minneapolis, MN) peat-based inocula, and Celpril (Manteca, CA) inoculated, lime-pelleted subclover seed. Duplicate...

Microbial ecology of an old-growth Douglas fir canopy

Creator:: Caldwell, Bruce A.
Abstract:: Microbial populations associated with the major substrates of the canopy of a 70 m old-growth Douglas fir were studied to determine potential activities. Seasonal samples from bark, foliage, epiphytic moss, lichens, and litter accumulations were collected to i) obtain population data, ii) to isolate the major groups of microorganisms present,...

Isolation and characterization of a leukocytolytic factor from Aeromonas salmonicida

Creator:: Fuller, David Wallace
Abstract:: The purpose of this study was to find what effect temperature and immunization has on the phagocytic activity of fish leukocytes against certain disease causing bacteria. Also proposed was the isolation and characterization of a leukocytolytic factor produced by one of these bacteria, Aeromonas salmonicida. Investigations revealed that temperature had...

A study of corynebacterial kidney disease of salmonid fishes

Creator:: Rowse-Eagle, Debra H.
Abstract:: This study was undertaken to compile a comprehensive review of the literature and to gain a better understanding of the host-parasite relationship in corynebacterial kidney disease of salmonid fishes. An indirect fluorescent antibody technique was developed which allowed differentiation of intra- and extracellular bacteria. This technique was used in combination...

Enteric Redmouth Bacterium of salmonids : a biochemical and serological comparison of selected isolates

Creator:: O'Leary, Patrick John
Abstract:: A comparison of the agglutinating and precipatiating antigens of Enteric Redmouth Bacterium (ERMB) was made. There are two major and one minor agglutinating antigens which describe two serotypes (I and II). Only serotype I metabolizes sorbitol. A bacterin from serotype I cross protected against a challenge of bacteria of serotype...
