Lipid Metabolism During Bacterial Growth, Sporulation, And Germination: An Obligate Nutritional Requirement In Bacillus Thuringiensis For Compounds That Stimulate Fatty Acid Synthesis, Kenneth W. Nickerson, Lee A. Bulla Jr.

Papers in Microbiology

The regulation of fatty acid biosynthesis by compounds that are required for growth of Bacillus thuringiensis was investigated using an in vivo assay developed to measure fatty acid synthesis in germinating spores. A minimal glucoseammonium- salts medium does not support growth even though previous radiorespirometric studies have shown B. thuringiensis to possess intact tricarboxylic acid and Embden-Meyerhof-Parnas pathways. Abundant growth does occur, however, when this medium is supplemented with either glutamate, aspartate, citrate, thiosulfate, cystine, or ethylenediaminetetraacetic acid. Cells held under non-growing conditions incorporate acetate into fatty acids; fatty acid synthesis is stimulated by the compounds that permit growth. These …

Populations Of Lepomis Auritus (Redbreast Sunfish) In A Thermally Influenced Section Of The James River, Virginia, John Rawls Saecker

Master's Theses

From October 1971 - September 1973, electrofishing was used to collect 1004 specimens of Lepomis auritus (year classes 0 - V) from a thermally influenced section of the James River near Blemo Bluff, Virginia. Collections of fish from the natural and heated water temperature habitats were analyzed as to year classes, season, length and sex.

Physical And Chemical Properties Of Outdoor Beef Cattle Feedlot Runoff, C. B. Gilbertson, J. R. Ellis, J. A. Nienaber, T. M. Mccalla, T. J. Klopfenstein

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Within the past decade, emphasis has been placed on the quality of our environment. Beef cattle feedlots have been singled out as a significant source of environmental pollution. Environmental protection provided by control facilities requires basic knowledge of the physical and chemical properties of feedlot runoff. This bulletin summarizes studies of physical and chemical properties of beef cattle feedlot runoff completed from August, 1968 through December, 1972.

Nutrition Education For The Elderly, Laurie Manahan

Loma Linda University Electronic Theses, Dissertations & Projects

Abstract not included.

Introduction

This paper examines the topic of nutrition education for the elderly. Only within the past decade has proper nutrition been recognized as making a major contribution to the health and well-being of the elderly. This recognition of the importance of nutrition in the later years has led to the recent establishment of many nutrition programs for the elderly. As nutrition education is seen as an important tool in improving the nutritional status of the elderly, many of these now programs include nutrition education components.

Part One of this paper discusses the relationship between nutrition and aging. …

The Effects Of Certain Steroids On The Growth Of Slime Mold, Physarum Polycephalum, Ching-Bun Paul Chen

Theses and Dissertations

The cortex of vertebrate adrenal glands secretes two major groups of hormones--glucocorticoids and mineralocorticoids. Glucocorticoids, which have an oxygen atom at carbon number 11, increase the rate of gluconeogenesis and increase the mobilization of lipids in mammals (Turner and Bagnara 1971). At the same time there is a decrease in protein synthesis. This latter effect may be homologous to a decrease in fibroblast growth in culture in the presence of certain corticosteroids (Ruhmann and Berliner 1965). The main function of mineralocorticoids, on the other hand, is to retain sodium ions. They have little or no gluconeogenic activity. Interestingly, however, these …

Ultrastructural Investigations Of The Host-Parasite Interface Of Pumpkin Cotyledons And The Fungus Sclerotinia Sclerotiorum, Mark Edward Richtsteig

Theses and Dissertations

Pumkin seedlings (Cucurbita maxima) were inoculated with the fungus Sclerotinia sclerotiorum (Lib.) de Bary. Center regions of non-infected and infected cotyledons of various lengths were cut into 1 x 2 mm strips and processed for ultrastructural investigations. Complementary portions of opposing non-infected cotyledons were also processed as control tissue, and contained fewer storage products in cells than cotyledons of comparable size from non-infected plants. Young non-infected cells contained distinct lipid bodies, protein bodies and electron dense inlusions which were translocated out of older cells by abundant plasmodesmata. Initally, infected cells became plasmolyzed, followed by breakdown of the cytoplasm. Host cells …

The Effect Of Lead And Zinc On Selenium Poisoning In Mice, Cynthia Joy Call

Theses and Dissertations

Trace elements, because they are effective in catalytic amounts, must be held in delicate balance with each other as well as with the macronutrients of the diet. Disturbances of these balances result in deficiency and toxicity symptoms. Toxic doses of selenium, lead, and zinc, for example, are known to cause anemia (1, 2, 3, 4) and growth depression (5, 3) in experimental animals.

Effect Of Salinity On Glycogen Content In The Brine Shrimp, Artemia Salinas, Of Great Salt Lake, Christon H. Merkley

Undergraduate Honors Capstone Projects

The brine shrimp, Artemia salinas, is one of the few organisms to be found in the hostile environment of the Great Salt Lake. Salt concentrations in the lake are found to exceed those in the oceans. In such an environment, the utilization of energy, even after it has been procured, presents a problem. The life inhabiting the lake has developed extraordinary adaptations to this and similar problems.

Electron micrographs produced by Dr. Nabil Youssef of Utah State University have revealed that unusual quantities of glycogen can be found in the muscle of brine shrimp taken from the Great Salt Lake. …

Trials With Trickle Irrigation Equipment At Morogoro Preliminary Report, M.E. Parkes, M. E. Madata

Tanzania Journal of Science

The use of trickle irrigation is discussed with reference to Tanzania. A split-split plot design experiment is described in which yields of tomato, onion, and cabbage are compared for trickle and hand-irrigated plots, with different levels of fertiliser treatment. Yields for trickle-irrigated plots were significantly greater only for tomatoes. These results were achieved during July to October and a second attempt to grow the same vegetables during December to March was unsuccessful. Further trials are required to obtain a suitable rotation of vegetable crops from both a nutritional and agronomic point of view. Experience with the trickle irrigation equipment is …

Sodium Bentonite In Ruminant Rations, Daniel P. Colling

Open Access Master's Theses (through 2010)

Sodium bentonite, an expanding clay, is being used in many different ways in industry today.The livestock and feed industry, for example, use it in many different ways.It is used as a pellet binder to maintain a fat test in dairy animals, as a digestive aid in the poultry industry and as a “buffering agent” in feedlot rations.

A two-pronged investigation was undertaken to determine the effect sodium bentonite could have on the ruminant feeding industry.One part of the investigation sought to determine if bentonite could partially or entirely alleviate subclinical lactic acidosis with problem rations.The other part of the investigation …

The Effect Of Iron Supplementation On The Endurance Capacity Of The Female College Athlete, Barbara B. Sachon

The major parameter of interest was the effect of iron supplementation on endurance capacity of female college athletes. Secondary parameters included the evaluation of the effect of iron supplementation on the following hematological variables: white blood cell count, red blood cell count, hemoglobin concentration, and hematocrit. Nineteen volunteer female students enrolled at the College of William and Mary in Williamsburg, Virginia served as subjects, All were members of the swimming team. All test trials and venipunctures were done at the women's gym at the College of William and Mary. There were two test periods.

All nineteen subjects performed a 500 …

Microbenthic Algal Production Of An Intertidal Sandflat In Little Creek Harbor, Virginia Beach, Virginia, Clayton Barry Shedrow

OES Theses and Dissertations

Estimated annual net microbenthic algal production of an intertidal sandflat on Little Creek Inlet, Virginia Beach, Virginia, was 105 g C/m². Seasonally, primary production was greatest during the summer and fall periods (38 and 49 g C/m², respectively). Productivity was found to vary directly with water temperature and standing crop of benthic diatoms, and inversely with incident solar radiation and standing crops of sedimentary chlorophyll 'a' and 'c'. Orthophosphate and nitrate-N appeared to be limiting factors, nitrate-N more so than orthophosphate. Mean annual net photosynthetic efficiency (based upon total light) for the microphytobenthic community was 0.09%. …
