Effects Of 6/85-Strain Mycoplasma Gallisepticum Inoculation Alone At 10 Weeks Of Age Or In Conjunction With Fmg Inoculation Overlays At 22 Or 45 Weeks Of Age On The Performance, Egg, Blood, And Visceral Characteristics Of Commercial Egg Laying Hens, Kristin Allo Viscione

Theses and Dissertations

The effects of 6/85-strain M. gallisepticum (6/85MG) inoculation alone or in conjunction with a F-strain M. gallisepticum (FMG) over-lay and its timing on the performance, egg, blood, and visceral characteristics of commercial egg laying hens were investigated. The applied treatments did not affect layer performance, but did affect yolk moisture and fatty acids, liver moisture, and plasma protein. The plasma protein and liver moisture changes may be indicative of the effects of the treatments on the hydration statuses of the birds during lay, whereas alterations in yolk palmitic, oleic, and linolenic acid levels with treatment may have been manifested by …

Genetic And Virulence Diversity Of Flavobacterium Columnare, Esteban Soto

Theses and Dissertations

Flavobacterium columnare is a freshwater fish bacterium responsible for columnaris disease, the second leading cause of mortality in pond raised catfish in the southeastern United States. Pulsedield gel electrophoresis (PFGE) is a particularly powerful tool in epidemiology and is now regarded as the gold standard for molecular typing of microorganisms. We developed methods for conducting PFGE on F. columnare, and determined its efficacy for characterizing F. columnare strains isolated from different locations in the Southeastern United States. Virulence diversity was observed in two different immersion challenge experiments conducted with 16 different isolates in channel catfish fingerlings. A direct correlation was …

The Effect Of Pasteurization Temperature On Consumer Acceptability, Sensory Characteristics, Volatile Compound Composition, And Shelf-Life Of Fluid Milk, April Lynne Gandy

Theses and Dissertations

The relationship among consumer acceptability, descriptive sensory attributes, and shelf-life was determined for 2 % milk pasteurized at 77, 79, 82, or 85?aC. Pasteurization temperature had no effect (p>0.05) on shelf-life. Consumers preferred (p<0.05) 79?aC over other treatments on day 0; however, six days post-pasteurization 79?aC milk was only preferred (p<0.05) over 77?aC. Consumers were grouped into eight clusters based on product liking for both day 0 and 6 evaluations. The largest cluster liked all pasteurization treatments, and 79?aC was highly acceptable to all consumers that liked milk. Similar sensory descriptors indicated the end of shelf-life for all pasteurization treatments even though treatments could be differentiated by descriptors on day 0. This research reveals that altering pasteurization temperature from 79?aC may cause a decrease in consumer acceptability to some consumers. Altering pasteurization temperature does not affect shelf-life or sensory descriptors and volatile compound profiles at the end of shelf-life.

Understanding The Nifm Dependence Of Nifh In Azotobacter Vinelandii: Functional Substitution Of Nifh By A Nifh-Chll Chimeric Construct In A Nifm- Strain, Kelvin Harris Jr

Theses and Dissertations

The enzyme nitrogenase catalyzes the energy-dependent reduction of dinitrogen to ammonia via biological nitrogen fixation. Nitrogenase is composed of two metalloproteins known as the molybdenum-iron (MoFe) protein and the iron (Fe) protein. The Fe protein, a 60-kDa dimer of the product of the nifH gene, contains a single 4Fe-4S cluster and two Mg-ATP-binding sites, one at each subunit. The Fe protein is the obligate electron donor to the MoFe protein. To date, no other mutual protein has shown to substitute Fe protein in biological fixation, and the NifH is functional only in the presence of the nifessory protein NifM. Interestingly, …

Effects Of White-Tailed Deer Herbivory On Forest Plant Communities, John Thrift

All Theses

ABSTRACT
The impact of white-tailed deer (Odocoileus virginianus) herbivory on forest ecosystems has received more attention as deer populations continue to increase in many areas. We investigated the effects of deer herbivory on plant communities in three different geographic regions to increase the general knowledge of herbivory impacts and also to investigate specific regional effects where research has been lacking.
Twelve exclosures were constructed in clearcut hardwood stands on the Clemson Experimental Forest, SC. Sapling, seedling, and understory species richness (S), Shannon's Diversity Index (H'), and Evenness (J') were compared between exclosures and paired control plots after the first and …

Thrombocyte Response To Lipopolysaccharide In Stress Induced Broiler Chicks, Farzana Ferdous

All Theses

The role of thrombocytes, nucleated blood leukocytes, on immune responses in chickens fed diets supplemented with vitamin C has not been studied in the past. This study investigates the effects of three types of diets(control, control with corticosterone, and control with corticosterone and vitamin C) in 14-day old broiler chicks on the expression of pro-inflammatory cytokines IL-1beta, IL-6, and IL-12 in thrombocytes. In addition, the effect of LPS, a microbial component to which broiler chicks can be exposed, on the expression of these pro-inflammatory cytokines was investigated. After two weeks of feeding, blood samples from the chicks were collected and …

Carbon Nanomaterials In Biological Systems, Sijie Lin

All Theses

ABSTRACT


This thesis intends to present, from the biophysical viewpoint, my study on understanding carbon nanomaterials in biological and environmental systems. Carbon nanotubes and fullerenes represent a major family of carbon nanoparticles which possess distinct electrical, optical and mechanical properties. However, the major hurdle for making carbon nanomaterials bioavailable lies in their tendency toward bundling, driven by hydrophobic interaction, van der Waals force, and pi-stacking. To overcome this problem, we used non-covalent binding of zwitterionic lysophopholipids (LPL) onto the external surfaces of single-walled carbon nanotubes (SWNTs). This method affords superior SWNT solubility in aqueous solution. The stability of SWNT-LPL complex …

Engineering Saccharomyces Ceresisiae For The Secretion Of An Extracellular Lipase, Gaynelle Stewart

LSU New Orleans Theses and Dissertations

Developing microbial systems capable of converting low cost lipids into value added products depends on the ability to acquire substrates from the growth media. Saccharomyces cerevisiae can acquire free fatty acids from the growth media and a portion of these lipids can be converted into new lipid products. However, they cannot acquire complex lipids from the growth media unless a nonspecific lipase is included. To circumvent lipase addition, we are genetically engineering S. cerevisiae to secrete a lipase into the growth media. We selected the LIP2 gene from Yarrowia lipolytica, which encodes a nonspecific lipase. Several modifications were made to …

Regulation Of Volume By Spermatozoa And Its Significance For Conservation Biology, Jennifer Barfield

LSU New Orleans Theses and Dissertations

Reproductive science plays an important role in conservation biology. Quantitative studies of basic reproductive biology in wildlife are critical for the development of successful assisted reproductive technologies. Investigation of the volume regulatory mechanism of spermatozoa could produce options to improve the cryopreservation of spermatozoa and provide a non-hormonal contraceptive option for men, both of which could have significant impacts on global biodiversity preservation. Volume regulation of somatic cells involves the movement of osmolytes through various channels, including potassium channels. The potassium channels involved in volume regulation of human, monkey, and murine spermatozoa were investigated. Flow cytometry was used to gauge …
