A Bacteriological Survey of a Freshwater Reservoir

A Bacteriological Survey of a Freshwater Reservoir

Date: January 1968
Creator: Stiles, John Clayborn
Description: In this study organisms that can be subcultured from lake water, using a prescribed procedure, limit, to an extent, the population, or portions of the population, that can be monitored. In essence, what is taking place is that a set of conditions is set forth and a study is made of the bacteria that will grow under these prescribed conditions.

Heat Resistance in Vegetative Cells and Cysts of Azotobacter

Heat Resistance in Vegetative Cells and Cysts of Azotobacter

Date: August 1969
Creator: Rosenthal, Raoul S.
Description: The purpose of the current study is to determine something of the nature of the heat resistance in Azotobacter, if in fact this is found to exist. An attempt is made to determine the specific physiological state associated with heat resistance as well as to resolve this resistance quantitatively.

Application of Fluorescent Antibody Methods for the Enumeration and Identification of Bacilus Cereus

Application of Fluorescent Antibody Methods for the Enumeration and Identification of Bacilus Cereus

Date: August 1969
Creator: Ferebee, Robert Newton
Description: This particular work is proposed as a test of the expedience of using the fluorescent-antibody technique as a method for enumeration and identification of certain strains of B. cereus that have been found to be effective in preventing taste and odor in water supplies resulting from certain Actinomycete blooms.

Obligately Thermophilic Nitrogen-Fixation in Some Soil Bacteria

Obligately Thermophilic Nitrogen-Fixation in Some Soil Bacteria

Date: August 1971
Creator: Milam, Mary
Description: In the work presented here, it is claimed that bacteria have been isolated which are capable of growth at high temperatures utilizing molecular nitrogen as their sole nitrogen source. Soil bacteria were isolated which grew at 55 C in nitrogen-free media. They were found to be obligatory thermophiles in nitrogen-free media and facultative thermophiles in media containing organically bound nitrogen.

Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Date: August 1970
Creator: Ferguson, Patricia Kaspar
Description: The purpose of this study was to see if any soil bacteria were able to use pentachlorophenol or sodium pentachlorophenate either aerobically or anaerobically as a sole carbon source, to see if any soil bacteria could survive in high concentrations of sodium pentachlorophenate, to determine the maximum concentration of sodium pentachlorophenate which permitted the growth of some soil bacteria, to see the effects of varying concentrations of sodium pentachlorophenate on the growth curves of soil bacteria capable of growing in its presence, and to see if any soil bacteria could degrade sodium pentachlorophenate.

A Determination of the Effects of Various Concentrations of Sodium Chloride upon the Growth of Three Species of Bacteria

A Determination of the Effects of Various Concentrations of Sodium Chloride upon the Growth of Three Species of Bacteria

Date: 1942
Creator: Davis, J. Floyd
Description: The problem in this investigation is to determine the effects of various concentrations of sodium chloride upon the growth of three species of bacteria. An effort has been made to solve this problem, not only by a study of the relevant literature, but also by laboratory research consisting of cultivation and observation of the three organisms which were arbitrarily chosen for this study.

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

Date: 1951
Creator: Ennis, Arthur F.
Description: The purpose of this problem is to determine the presence and extent of antibiotic materials as found in the oleoresins of a selected group of garden vegetables. The problem has consisted of, first, the collection and preparation of specimens of twenty-five commonly used garden vegetables; second, the extraction of the oleoresins from these; third, the determination of the inhibitory and other effects of these oleoresins against several strains of selected gram-positive and gram-negative bacteria; and fourth, the evaluation of the potentialities of these oleoresins with regard to their future use as medicinal prophylactics and therapeutics.
