The Fixation of Atmospheric Nitrogen

Creator:: Fairchild, Jackson Kenelem
Abstract:: Much has been accomplished in the last few years toward the conservation of natural resources, and in this work the engineer has taken a leading part. The prevention of unnecessary waste, the utilization of hitherto useless by-products, and the economic production of the world's necessities are important features of this...

An investigation of the metabolism of poly-β-hydroxybutyrate and its possible role in nitrogen fixation in soybean root nodules

Creator:: Wong, Peter Pasteur, 1941-
Abstract:: A major objective of this investigation was to determine the possible roles, if any, of poly-β-hydroxybutyrate and products of its metabolic breakdown in symbiotic nitrogen fixation by nodule bacteroids. Changes in poly -β- hydroxybutyrate content and in activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and isocitrate lyase were studied under various conditions...

Nitrogen fixation associated with grasses and other species in Oregon

Creator:: Nelson, Arthur Duane
Abstract:: Nitrogen fixation in both natural and domestic grasslands of Oregon was studied using the acetylene reduction assay. A substantial number of these tests made gave positive acetylene reduction activity. Rates in the range of 60g N₂ fixed/ha/day were observed for some Agrostis species. Assuming that this rate proceeds for 100...

Nitrogen fixation by Purshia tridentata : some ecological aspects and root nodule anatomy

Creator:: Dalton, David Andrews
Abstract:: This study examines several aspects of nitrogen fixation by Purshia tridentata (Pursh) D. C., a rosaceous shrub widespread in the central Oregon pumice region, especially as an understory species in Pinus ponderosa and Pinus contorta forests. Anatomical studies of root nodules under the light microscope revealed strong similarities to other...

Investigations into the physiology of nitrogen fixation : Part I. Nickel metabolism of plants and bacteria : Part II. Peroxide scavenging in soybean root nodules

Creator:: Dalton, David Andrews
Abstract:: PART I. The concentration of nickel in some soils may be insufficient to meet the requirements of enzymes such as urease in soybeans and hydrogenase in Rhizobium. Nickel availability in soils was examined by measuring microbial urease activity in soils which were treated with glucose and urea. Supplemental nickel was...

Nitrogen fixation by scotch broom (Cytisus scoparius L.) and red alder (Alnus rubra Bong.) planted under precommercially thinned Douglas fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Helgerson, O. T.
Abstract:: Red alder (Alnus rubra Bong.), scotch broom (Cytisus scoparius L.) and snowbrush (Ceanothus velutinus Dougi ) were planted under precommercially thinned Douglas-fir (Pseudotsuga iuenziesil Mirb Franco) in the central Oregon Cascades. Plug grown red alder had significantly greater survival than all wildling propagules except for the second broom planting Browsing...

Symbiotic nitrogen fixation by Ceanothus species

Creator:: Wollum, Arthur George
Abstract:: The primary intent of this study was to clarify the role of the endophyte in the Ceanothus symbiosis. A technique utilizing a 20 percent solution of H₂O₂ was developed which allowed the isolation of a Streptomyces sp. from the root nodules of some Ceanothus species. Further characterization suggested that the...
