Microbial Utilization of a Certain Hydrocarbon Insecticide

Microbial Utilization of a Certain Hydrocarbon Insecticide

Date: August 1951
Creator: Dorman, Homer L.
Description: This problem includes, first, the isolation and identification of microorganisms which utilized the hydrocarbon insecticide as a sole source of carbon and energy; second, a determination of the effect on plants sprayed with the hydrocarbon medium as compared with the effect on plants sprayed with the hydrocarbon medium containing a good growth of hydrocarbon-utilizers; and third, a determination of the ability of laboratory stock cultures of organisms to utilize or remain alive in the hydrocarbon medium.

Biological Indices of Stream Pollution

Biological Indices of Stream Pollution

Date: August 1952
Creator: Russell, James C.
Description: A thorough biological survey and evaluation is a lengthy and expensive project. The number of technically trained persons required prevent its use by most public agencies. Since public health departments are the groups most frequently concerned with measuring the effects of pollution in streams, a need exists for a simplified method of sanitary survey. Recognizing this need, the Texas Heal Department assigned the writer the problem of devising a method of survey which would require a field party of two and could be conducted entirely from a mobile field laboratory.

The Inhibition of Fungal Contaminants in Cultures of Mycobacterium Tuberculosis

The Inhibition of Fungal Contaminants in Cultures of Mycobacterium Tuberculosis

Date: 1951
Creator: Wright, Noble M.
Description: The problem of conatmination in culture media for Mycobacterium tuberculosis has not been solved completely, and for this reason the work herein presented was carried out. In this work experiments were made testing the effect of actidione in inhibiting certain ones of the higher fungi.

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.

A Microbial Survey of Raw Ingredients Used in Finished Products at Kraft Foods Company, Garland, Texas

A Microbial Survey of Raw Ingredients Used in Finished Products at Kraft Foods Company, Garland, Texas

Date: 1951
Creator: Langston, Clarence Walter, Jr.
Description: The purpose of this investigation is to determine through routine checks the number of organisms present in the various raw ingredients used for the preparation of foods. The problem has consisted of, first, a determination of the total bacterial population by numbers; second, a determination of the incidence of colon bacteria in the samples examined; third, a determination of the presence of yeasts and molds; and fourth, an attempt to utilize this information obtained in judging the methods of handling the raw ingredients before they are used in the processing of foods.

A Rapid Modification of a Standard Disk-plate Antibiotic Susceptibility Test

A Rapid Modification of a Standard Disk-plate Antibiotic Susceptibility Test

Date: January 1955
Creator: Jackson, Leslie Warren
Description: The objective of the work reported in this paper is one of a two-fold nature. The first objective is to develop a disk-plate sensitivity test that is more rapid than that of existing methods. The second requisite is that the materials, techniques, interpretation, and reporting of results be the sane as those required for the disk-plate method described in the Difco Manual.
