The Antibiotic Activities of Some Members of the Cactaceae Family

The Antibiotic Activities of Some Members of the Cactaceae Family

Date: 1951
Creator: Gilmore, Derward E.
Description: This problem has been concerned with, first, the collection of sixteen species of plants belonging to Cactaceae family; second, the drying of these and the extraction of the oleoresins thereof; third, the determination of the extent to which these substances inhibit the growth of ten gram-positive and ten gram-negative bacterial organisms; and fourth, a determination of the possible utilization of these extracts a prophylactic or chemotherapeutic agents.

The Antibiotic Effect of Pigmented Actinomycetes

The Antibiotic Effect of Pigmented Actinomycetes

Date: 1951
Creator: Cichon, Casimir Joseph
Description: This thesis attempts, first, to correlate pigmentation of actinomycetes with the degree of antibiocity; second, to establish the most favorable means of producing a rich luxuriant pigmentation in the individual organism studied by enriching favorable media with specific types of proteins and amino acids.

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.
