Lipids and Phospholipase Activity of Vibrio Cholerae

Description: One purpose of this investigation is to determine the fatty acid and lipid content of typical Vibrio cholerae cells. The comparison of cholera lipid constituents with those of closely-related bacteria might be of taxonomic value. Furthermore, chemical characterization of the cholera vibrio could provide useful criteria for identification of these disease-producing microorganisms.

A Characterization of Liver Glyoxalase I From Normal Mice and Mice Bearing Lymphosarcoma

Description: The purpose of this investigation was (1) to isolate and purify glyoxalase I from the livers of normal DBA/lJ mice and the livers from mice bearing a lymphosarcoma tumor; and (2) to determine, at least with respect to glyoxalase I, if the tumor has an effect on the chemical properties or structure of macromolecules in an organ removed from tumor locale and not histologically affected by its presence.

Ecological Energetics of the Dobson Fly, Corydalus Cornutus

Description: Rates and energies of consumption (C), egestion (F), assimilation (A), respiration (R), growth (Pg), production of exuviae (Pev), and production of egg masses (Pr) and associated efficiencies, and the effects of seasonal temperature, weight and metamorphic stage upon these factors were examined for a typical individual and cohort of Corydalus cornutus (L.) from a stream in North-Central Texas (330 23'N, 97*5'W). Dobson flies are apparently univoltine in the study area, with 11 larval instars. E… more

Microorganisms Associated with a Spray Irrigation System

Description: The area of research for this thesis concerns the role played by microorganisms in the process of organic breakdown of waste effluent. Although considerable research has been done since the early 1950's, little consideration has been given to the role of the microorganisms in this type of waste water purification.

Studies of Mouse Hypersensitivities

Description: Having considered the data collected thus far concerning immediate and delayed hypersensitivity reactions in the mouse, the experimentation following is devised essentially to follow the pattern of Crowle in the production and testing for immunoresponse. Instead of using the normal solvent, that is, acetone, this work is also intended to partially evaluated the use of dimethyl sulfoxide as a solvent for the contact allergin, dinitroflurobenzene.

Phosphorus Metabolism in Atypical Mycobacteria

Description: The design for this study was tri-phasic: 1) to establish growth time patterns for each group of atypical mycobacteria, 2) to demonstrate the dynamic state of phosphorus in the various fractions by determining its incorporation and turnover, 3) to determine quantitatively the amount of phosphorus in each fraction.

The Effects of the Soil Conditioner, Superbio, Upon the Cellulose Decomposing Bacteria and the Crop Yield of a Soil

Description: The purpose of this investigation was to determine if a commercial soil conditioner, Superbio, can improve crop yield, and if the "advertised" soil improvement might be due to an increase in the activity and numbers of aerobic cellulose decomposing bacteria following treatment.

Memory Consolidation in Avoidance-Conditioned Goldfish: Changes in Brain Protein-Synthetic Patterns

Description: Three groups of goldfish were prepared; naive, avoidance-conditioned and pseudo-conditioned animals. Five pseudo-conditioned fish were avoidance trained later and found to have no measurable acquisition of the avoidance conditioning paradigm. Several protein fractions were found to have significantly different rates of synthesis when compared across groups. The possible involvement of these proteins in the memory storage process was discussed.

Effects of pH and Substrate on Growth of Escherichia Coli and Pseudomonas Aeruginosa in Mixed Continuous Culture

Description: The express purpose for doing this project was to develop methods for the continuous culture of E. coli and P. aeruginosa as a mixed population, and to apply these methods in studying the effects of pH and substrate upon the growth of these two organisms in mixed continuous culture.

Assimilation of Organic Carbon by Aquatic Actinomycetes

Description: There were two purposes of this investigation: the first was to develop a method for studying spore germination, hyphal growth and mycelial development of the aquatic actinomycetes under the microscope so that the life cycle of this organism could be continuously followed. The second purpose was to determine the rate of carbon utilization from various types of nutritional sources, and to correlate this with the colony development and spore formation.

Selected Physiological and Biochemical Studies on Blue-Green Algae

Description: Twenty-two different unialgal clonal isolates have been obtained at random for experimental purposes over a period of about one year. Also, during this period, at least 12 other species or strains have been isolated into unialgal cultures which had not yet been identified and/or significantly cleared of heterotrophic contaminants.
