Assimilatory Nitrate Reduction In Azospirillum Brasilense Sp7 : Mutants And Expression Of The Genes In Escherichia Coli Recombinant Strains, Kang-Yell Choi
Electronic Theses and Dissertations
The intensive study of A. brasilense that has been undertaken is due in part to the desire of microbiologists to understand its nitrogen metabolism. A. brasilense can perform all of the reactions of the nitrogen cycle except for nitrification, however, the details are not yet completely understood on any of the processes. In agriculture, A. brasilense not only supplies fixed nitrogen and nutrient to cereals; but also it significantly contributes to the loss of nitrogen from the soil by denitrification. Enormous amounts of fixed nitrogen are unfortunately lost from the soil to the atmosphere by this denitrification. The elucidation of …

Ozonation Pilot Treatment Of A Surface Water Supply For Odor Control, Fairmont, Minnesota, Lyle Duane Munce
Electronic Theses and Dissertations
Odor is an important factor in evaluating the quality of water. The presence of odor in water can impair its use for drinking, cooking and recreation. Waters having odors are not necessarily unhealthful to drink, but often are considered so by consumers. Odors in drinking water supplies originate from natural and/or man-made sources. Man-made odors can be derived from organic and inorganic chemicals used or produced by industry. These odors can come directly from odorous chemicals such as phenols or pyridines. Or, the odors can result from the anaerobic decomposition of chemicals. Sometimes certain chemicals might react with other constituents …

Effect Of Preconditioning On Performance And Health Of Feeder Steers, Janie Katrin Swann
Electronic Theses and Dissertations
Ranchers are continuously looking for ways to produce heavier, healthier calves at sale time. There are many on-ranch management practices performed to accomplish this, including early weaning, creep feeding, preconditioning and implanting. However, over time results may be variable. Before deciding on a certain method for handling a calf crop, ranchers must carefully evaluate their own situation, including facilities, labor, feed and pasture conditions. Feedlot operators should also be aware of previous management of calves since preshipment practices may affect performance in the feedlot. In an effort to evaluate the preconditioning program in South Dakota, performance of preconditioned and nonpreconditioned …
