Glucocorticoid regulation of salmonid B lymphocytes

Creator:: Tripp, Ralph A.
Abstract:: The in vitro effects of cortisol in regulating salmonid B cell functions were investigated. B cells at three distinct stages of differentiation were examined for cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage of the precursor, 2) during the intermediate stage of differentiation associated with clonal...

The activity of extracellular enzymes in starved and unstarved cells of a psychrophilic marine vibrio

Creator:: Amthor, Kerstin
Abstract:: The psychrophilic marine Vibrio sp., ANT-300, was able to utilize a variety of carbon sources that can be considered typical for the marine environment. The organism grew abundantly on glucose and serine. Chitin was hydrolyzed even when it was offered as the only carbon source, while no growth occurred on...

Delineation of the composition of an indigenous soil population of Rhizobium meliloti in root nodules of uninoculated field grown Medicago sativa L.

Creator:: Jenkins, Michael B.
Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...

Full Text:: nodule numbers declined from 66 to 11 per plant between the first and third harvests. All isolates

The effect and metabolism of 5'-methylthioadenosine in normal and 5'-methylthioadenosine phosphorylase deficient mammalian cells

Creator:: White, Michael William
Resource Type:: Dissertation
Full Text:: studied using two mouse cell lines, one 5'-methylthioadenosine phosphorylase deficient (MTAase-) the

Persistent infection of salmonid cell lines with infectious pancreatic necrosis virus : a model for the carrier state in trout

Creator:: Hedrick, Ronald Paul
Abstract:: Persistent infections with infectious pancreatic necrosis virus (IPNV) were established in two salmonid cell lines and in live brook trout. Virus inocula containing high concentrations of defective interfering IPNV enhanced but were not a requirement for the establishment of persistent infections in cell lines derived from steelhead trout (STE-137) and...

Starvation-survi[v]al studies on a marine Vibrio sp. and other selected marine bacteria

Creator:: Amy, Penny Susan
Abstract:: The starvation-survival patterns of 16 freshly isolated open ocean bacteria and in a psychrophilic Vibrio sp., Ant-300, were determined. These isolates displayed three survival patterns as determined by viable cell count. These were (a) a rapid increase followed by a decrease to a constant value (pattern of Ant-300 and 7...

Homospermidine, spermidine, and putrescine : the biosynthesis and metabolism of polyamines in Rhizobium meliloti

Creator:: Tower, Paula Allene
Abstract:: Rhizobium, in symbiotic association with leguminous plants, is able to fix atmospheric nitrogen after first forming root nodules. Since polyamines are associated with and found in high concentration in rapidly growing cells and are thought to be important for optimal cell growth, it is possible that these polycations are involved...

The biosynthesis of ethylene from methionine in Saccharomyces cerevisiae

Creator:: Jones, Paul Aikens
Abstract:: Methionine metabolism, leading to the biosynthesis of ethylene in Saccharomyces cerevisiae does not appear to involve S-adenosylmethionine (SAM) and aminocyclopropanecarboxylic acid (ACC), based on the lack of ethylene synthesis when both SAM and ACC were incubated in the presence and absence of cells. Thus, the mechanism leading to the formation...

Coliphage T3 S-adenosylmethionine hydrolase : properties of the cloned gene and consequences of its expression in Escherichia coli

Creator:: Hughes, Jeffrey A.
Abstract:: To begin the development of a research tool for use in the in vivo study of S-adenosylmethionine (SAM) metabolism, I attempted to locate, isolate, clone and elicit the expression of the SAM hydrolase gene (E.C. 3.3.1.2) of the coliphage T3. The gene was isolated and cloned into the M13mp8 cloning...

Survival of fecal coliform bacteria in sludge-amended soils

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...
