Anatomical & Phenological Variation Of Liquidambar Styraciflua L. Under Controlled Environmental Conditions, William Randel

Masters Theses & Specialist Projects

A large degree of variation in fiber tracheid length, wood specific gravity, and time of apical bud formation existed within two populations of Liquidambar styraciflua L. from south central Kentucky. The variation exhibited by these populations may be attributed to the self-sterility of Liquidambar and the variable environment of south central Kentucky.

Variation of fiber tracheid length and wood specific gravity within the two populations was significant. Fiber tracheid length was dependent on temperature and photoperiod while wood specific gravity was primarily dependent on temperature. A significant level of variation was also evident between the two populations regarding tracheid length. …

Effects Of Photoperiod, Temperature And Preconditioning On The Molt Cycle Of Samples From A Michigan Population Of Orconectes Immunis (Hagen), Robert Van Hoff

Masters Theses & Specialist Projects

Immature Orconectes immunis were obtained from Michigan in August, 1973, and July 1974 to determine the effects of photoperiod and temperature on the molt cycle of the crayfish and to test the effects of preconditioning on this species at a cold (7C) temperature from 45 to 90 days. Two sets of 3 experiments were conducted, each involving photoperiod, temperature and preconditioning. The first experiment of each set was initiated within a day after bringing the animals from the field, the subsequent two experiments of each set being initiated at 45-day intervals thereafter.

The Metabolism Of Tartaric Acid By Aspergillus Ficuum, Larry Daniel

Masters Theses & Specialist Projects

Soil samples were screened for organisms which decompose tartaric acid as an energy source. Several microorganisms were isolated which were capable of metabolizing tartaric acid. The organism which grew best was identified as Aspergillus ficuum and used in this study. This organism, when grown in tartrate medium, resulted in a decrease in optical rotation and density of the culture medium. The pH of the culture filtrate increased with a concurrent increase in mycelial weight. Analysis of culture filtrates by gas chromatography indicate that the first intermediate compound detected in tartrate decomposition by A. ficuum is glycolic acid. The terminal metabolite …

The Production Of Epoxysuccinic Acid By Fungi, John Dibble

Masters Theses & Specialist Projects

Seven strains of Aspergillus fumigatus and five strains of Paecilomyces varioti known to produce trans-l-epoxysuccinic acid (ESA) in a fermentation medium were compared for total acid production. It was found that A. fumigatus NRRL 2327 accumulated the greatest concentration of total acid determined by titration for soluble calcium.

Using a method of gas -liquid chromatography developed for this study, it was found that P. varioti NRRL 1123 accumulated significant quantities of ESA and succinic acid and a trace of an unidentified acid in a fermentation medium. The maximum accumulation of ESA was not reached by the 9th day of …

Partial Purification & Kinetic Studies Of Nicotinamide Adenine Dinucleotide Phosphate-Specific Isocitrate Dehydrogenase Of Phycomyces Blakesleeanus, Michael Meredith

Masters Theses & Specialist Projects

The nicotinamide adenine dinucleotide phosphate -specific isocitrate dehydrogenase (threo-Ds(+) isocitrate: NADP⁺: oxidoreductase [decarboxylating]; E.C. 1.1.1.42.) of Phycomyces blakesleeanus was partially purified. The method used to purify the enzyme was a combination of protamine sulphate precipitation, ammonium sulphate fractionation, and ion exchange and gel filtration chromatography. The NADP⁺ -specific IDH was purified from an initial specific activity of 0.05 units/mg of protein to a final specific activity of 1.5 units/mg protein in solution.

Molecular and reaction characteristics were explored. Employing gel filtration the molecular weight of the enzyme was determined to be 88,000. The forward reaction was found …

The Fresh-Water Mussel Industry Of The Lower Tennessee River: Ecology & Future, Randall Grace

Masters Theses & Specialist Projects

The fresh-water mussel industry of the Tennessee River is nearing an end. Overharvesting, habitat alterations, and pollution are the major contributors to the depletion of the mussel resource, upon which the shell industry is based. A history of unconcern by shell harvesters and weak conservation enforcement by governmental agencies, has left the major waterways of the United States nearly void of commercial clams. The lower Tennessee River presently supplies the mussel industry with nearly all the important species of mollusks. If this industry is to be maintained in the United States, ways to preserve and propagate the mussel population must …

Lesion Formation In The Liver Of Mice Caused By Metabolic By-Products Of Hymenolepsis Microstoma, Gary Simpson

Masters Theses & Specialist Projects

The presence of lesions in the liver of mice is associated with the infection of these mice with the common bile duct -dwelling cestode, Hymenolepis microstoma. Lesions develop even though there is no direct contact between the cestodes and the liver. It was found in this investigation that administration to mice of Tyrode's solution, in which cestodes had been incubated for 24 hr, resulted in liver lesions comparable to those observed in normal infections. The administration of the causative substance by either per os intubation or intraperitoneal injection produced similar lesions. Further studies revealed that the active lesion - …

The Effectiveness Of The Nitrate Ion Selective Electrode As A Qualitative Method For Low Levels Of Nitrate, Linda Blaine

Masters Theses & Specialist Projects

The nitrate ion specific electrode has been used to measure nitrate concentration in plant tissue. Nitrate concentration, as nitrate ion activity, can be read rather simply in an aqueous extract of the plant tissue in somewhat the sane manner as a pH measurement would be taken, In contract to more time consuming chemical methods.

A previous study of nitrate concentrations in barley treated with the growth retardant chemical, B-Nine (succinic acid 2, 2 dimethylhydrazide), had been carried out by the colorimetric method of Wooley, Hicks and Hageman. The study indicated lower nitrate concentrations in treated plants, as compared with untreated …

Masters Theses & Specialist Projects

Phenological and cultural studies of common dandelion (Taraxacum officinale Weber) were conducted from 1969 to 1971 at Bowling Green, Kentucky. The phenological studies were based upon dandelion plants which were found growing in a Kentucky bluegrass lawn or in open lots. At this location the dandelion flowered throughout the year. Maximum flowering occurred during April and a secondary peak occurred in September and October. The number of flowering stems per square meter was not correlated significantly with precipitation, temperature, or day length. Length of stem was positively correlated with temperature and day length. The plants exhibited diurnal variation in flowering …

A Phytosociological Study Of A Relict Hardwood Forest In Barren County, Kentucky, Christine Bougher

Masters Theses & Specialist Projects

Although general information is readily available concerning the structure and composition of deciduous forests, especially in the eastern part of the United States, there seems to be little specific information concerning forest composition in the Commonwealth of Kentucky. The lack of phytosociological studies prior to the development of the land, and the extent of land development in Kentucky, has led to a paucity of information regarding the natural forest vegetation of the Commonwealth. To the author's knowledge, there are few publications dealing with the vegetational composition of relict or virgin forests in Kentucky. It is apparent that there is a …
