Effects Of Fecally Contaminated Feed By Starlings On Growing Swine & Mice, Pat Schuster

Masters Theses & Specialist Projects

The effects of feed contamination by droppings of starlings (Sturnis vulgaris) on certain growth parameters in swine (Sus scrofa) were measured from January 25 to March 1, 1979 at the Western Kentucky University farm. Weight gain, feed-conversion efficiency and feed rejection by swine fed varying levels of contaminated feed were analyzed and found to be non-significant at the fecal concentrations used.

Laboratory mice (Mus musculus) were fed varying concentrations of starling feces in standard mouse chow; weight gain, feed-conversion efficiency and feed rejection were measured. At 0%, 10%, 25% and 50% concentrations, significant differences …


Analysis Of Tartaric Acid In Fermentation Broth, Lih-Jen Leu Aug 1979

Analysis Of Tartaric Acid In Fermentation Broth, Lih-Jen Leu

Masters Theses & Specialist Projects

Tartaric acid accumulation in fermentation broth of Gluconobacter suboxydans was investigated qualitatively with paper chromatography and thin-layer chromatography. Comparisons were made using six different solvent systems and four different chemical indicators commonly used in chromatography.

Attempts were made to establish a routine method for quantitative analysis of tartaric acid. Spectrophotometry was used to detect possible metabolites resulting from glucose oxidation by G. suboxydans in different analytical separations. A combined method of ion-exchange column chromatography and paper chromatography followed by ammonium meta-vanadate spectrophotometric analysis differentiated 5-oxogluconic acid and tartaric acid and thus gave better quantitative results in the determination of tartaric …

Isolation And Identification Of Yeasts From The Barren River, Richard Vanenk

Masters Theses & Specialist Projects

The Barren River was sampled twice monthly for one year to obtain data on aquatic yeasts. Sites upstream and downstream of the Bowling Green sewage plant, as well as the sewage effluent, were sampled to ascertain if the effluent had any effect on the yeast population of the river. Sporadic yeast counts were obtained which averaged 40 CFU/ml for the effluent, while the river averaged 15 CFU/ml. A total of 318 yeasts were isolated and identified during the study, including 16 different genera with Cryptococcus being the most common. Cryptococcus laurentii occurred most frequently of the 67 different species identified. …


Isolation & Enumeration Of Clostridium Perfringens From The Barren River Above & Below The Effluent Of The Bowling Green, Kentucky, Sewage Treatment Plant, Michael Hansen May 1979

Isolation & Enumeration Of Clostridium Perfringens From The Barren River Above & Below The Effluent Of The Bowling Green, Kentucky, Sewage Treatment Plant, Michael Hansen

Masters Theses & Specialist Projects

Samples from five sites on the Barren River were assayed during a one year period from March 1978 to February 1979 for the presence of Clostridium perfringens. These five sites were chosen in relation to their location to the effluent discharge pipe from the Bowling Green, Kentucky, sewage treatment plant. One collection site was located upstream from the discharge point; one station was directly from the mouth of the pipe; and three were located at intermittent points downstream from the discharge point.

When counts on the primary isolation medium, egg yolk-free tryptose-sulfite-cycloserine agar (EYF-TSC agar), were compared for each …


Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt May 1979

Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt

Masters Theses & Specialist Projects

Reciprocal plantings of populations of broomsedge, taken from an abandoned strip mine and from an abandoned farm plot in south central Kentucky, on strip mine spoil and abandoned field soil resulted in patterns of populations differentiation. Clonal plantings of populations from strip mine habitats and old field development appeared equal in height and biomass when grown on old field soils in both field trials and growth chamber studies. Populations when planted in strip mine soils in field trials and controlled growth experiments. Later flowering in strip mine populations may be a key to survival strategy in the harsh microclimates of …

The Effects Of Ph On 5-Oxogluconate Production By Gluconobacter Suboxydans, Neng-Chyang Leu

Masters Theses & Specialist Projects

The metabolism of glucose to 5-oxogluconate by Gluconobacter oxydans subsp. suboxydans (Gluconobacter suboxydans) at different pH values, glucose concentrations and phosphate buffer concentrations was studied. Bacterial growth, gluconic acid accumulation and 5-oxogluconate production were related to both pH and phosphate buffer concentration in the medium.

In media containing 2-3% glucose, 0.3% yeast extract and 0.3 M phosphate buffer, the optimal pH range for the bacterial growth was pH 6.4-7.0; the optimal pH range for gluconate production was pH 6.4-6.8; and the optimal pH range for 5-oxogluconate production was pH 6.6-7.0. Lowering the pH to 6.4 favored gluconate accumulation …


The Histopathology Of Acanthocephalan Infections In The Rainbow Darter, Etheostoma Caeruleum, J. Melissa Mcdonough May 1979

The Histopathology Of Acanthocephalan Infections In The Rainbow Darter, Etheostoma Caeruleum, J. Melissa Mcdonough

Masters Theses & Specialist Projects

Responses of naturally infected Etheostoma caeruleum to the presence of the acanthocephalans, Acanthocephalus dirus and Pomphorhynchus bulbocolli, were observed in 10u sections of intestines stained with hematoxylin and eosin. Both parasite species caused tissue damage to the host and elicited host responses. The major difference in parasite destruction was shallow tissue penetration by A. dirus proboscides while the proboscides of P. bulbocolli had deeper penetration and capsule formation. The most common parasite was P. bulbocolli, yet concurrent infections were not uncommon. Effects of concurrent infection were a combination of single species effects on the host. Connective tissue hyperplasia was …
