Growth Inhibition of Chlorella Pyrenoidosa TX71105 by an Unknown Soil Bacillus

Date: August 1968
Creator: Harrel, Steve K.
Description: The purpose of this paper is to present data on the nature of mixed cultures of algae and bacteria and to report new evidence of growth inhibition of Chlorella by a bacterial contaminant isolated from a soil environment.

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.

The Histological Effects of Injections of Fish Pituitary Extracts on the Testes of Male Frogs, (Rana Pipiens), and the Reproductive System of Immature Mice

The Histological Effects of Injections of Fish Pituitary Extracts on the Testes of Male Frogs, (Rana Pipiens), and the Reproductive System of Immature Mice

Date: 1949
Creator: Robertson, William George
Description: The purpose of this investigation was first, to make a histological and cytological study of the testis of male frogs, Rana pipiens, and to determine if there were tissue or cellular changes as well as physiological effects caused by fish pituitary-extract injections. Second, to determine if injections of fish pituitary extract into immature female white mice caused histological changes in the ovaries and uteri.

The Immune Response of Guinea Pigs as Influenced by Hypobaric Pressure and Normoxic Environment (Part I); Membrane Filter-Fluorescent-Antibody Method for Detection and Enumeration of Bacteria in Water (Part II)

The Immune Response of Guinea Pigs as Influenced by Hypobaric Pressure and Normoxic Environment (Part I); Membrane Filter-Fluorescent-Antibody Method for Detection and Enumeration of Bacteria in Water (Part II)

Date: August 1969
Creator: Reeder, Dennis James
Description: In this work experimental design and tests were established to determine whether antibody production in guinea pigs injected with a bacterial antigen is Influenced by the environment of simulated high altitude with normoxic conditions. Hematological and electrophoretic studies were simultaneously run with the antibody determinations as a check on related responses of the animals.

An Immuno-Electron Miscroscopy Study of the Slime Layer Antigen of Pseudomonas Aeruginosa

An Immuno-Electron Miscroscopy Study of the Slime Layer Antigen of Pseudomonas Aeruginosa

Date: May 1972
Creator: Pardue, Robert L.
Description: This investigation was concerned with the relationship of the slime layer material of Pseudomonas aeruginosa, Verder and Evans strain 1369, to the presumably somatic "O" type of antigen used by these authors as the base for their serological schema.

The In Vitro Bactericidal Activity of Antiserum Against Pseudomonas Aeruginosa

The In Vitro Bactericidal Activity of Antiserum Against Pseudomonas Aeruginosa

Date: May 1972
Creator: Stanford, Shirley A.
Description: The purpose of this research was to attempt to duplicate the in vitro bactericidal test against Pseudomonas aeruginosa as reported by Bjornson and Michael and to correlate agglutinating titer of an antiserum to protective activity.

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

In Vitro Determination of the Cellulose-Decomposing Rates of Twelve Denton County, Texas Soils

Date: 1950
Creator: Heather, Carl D.
Description: In this study twelve types of top soil were collected under aseptic conditions. The cellulose-decomposing rates of these were compared in order to determine the relative rates in the cellulose-decomposing potential of the microorganisms involved. Furthermore, this investigation is designed to acquire pertinent information on the rate at which natural cellulose materials are returned to available plant food.

The In Vitro Interaction of 3-Methylcholanthrene with Deoxyribonucleic Acid

The In Vitro Interaction of 3-Methylcholanthrene with Deoxyribonucleic Acid

Date: August 1967
Creator: Chapel, J. Frederick
Description: The purpose of this thesis is to report the interaction of aromatic hydrocarbons with DNA and to attempt to determine the relative binding affinities. The effect of the hydrocarbons on the continuity of the DNA molecule has been studied also and discussed.
