Isolation and Characterization of the Operon Containing Aspartate Transcarbamoylase and Dihydroorotase from Pseudomonas aeruginosa

Isolation and Characterization of the Operon Containing Aspartate Transcarbamoylase and Dihydroorotase from Pseudomonas aeruginosa

Date: May 1993
Creator: Vickrey, John F. (John Fredrick), 1959-
Description: The Pseudomonas aeruginosa ATCase was cloned and sequenced to determine the correct size, subunit composition and architecture of this pivotal enzyme in pyrimidine biosynthesis. During the course of this work, it was determined that the ATCase of Pseudomonas was not 360,000 Da but rather present in a complex of 484,000 Da consisting of two different polypeptides (36,000 Da and 44,000 Da) with an architecture similar to that of E. coli ATCase, 2(C3):3(r2). However, there was no regulatory polypeptide found in the Pseudomonas ATCase.

Isolation and Identification of an Odor Compound Produced by a Selected Aquatic Actinomycete

Isolation and Identification of an Odor Compound Produced by a Selected Aquatic Actinomycete

Date: August 1968
Creator: Henley, Don E.
Description: The purpose of this study was to develop an efficient method for the concentration of specific volatile taste and odor compounds produced by a selected aquatic actinomycete. A second purpose was to isolate and identify the specific taste and odor compound present in the highest concentration.

Isolation and Identification of Bacterial Species Associated with the Common House Fly and Three Species of Cockroaches

Isolation and Identification of Bacterial Species Associated with the Common House Fly and Three Species of Cockroaches

Date: 1951
Creator: Morland, Clifford L.
Description: In an attempt to demonstrate the role of insects as possible carriers of pathogenic bacterial organisms this investigation has been concerned with the determination of the microbial population associated both internally and externally with the common house fly and three species of the cockroach.

Isolation and Partial Characterization of a Bacterium Which Gives Off Filtrable Cells

Isolation and Partial Characterization of a Bacterium Which Gives Off Filtrable Cells

Date: May 1973
Creator: Siu, Henry H. W.
Description: The present study was on the isolation of a bacterium capable of producing filtrable forms which passed through the 0.45ยต filter membrane and regenerated the parental form; the testing of the true filtrability of the isolate; the relationship between growth of the isolate and appearance of filtrability; partial characterization of the isolate and visualization of the elements that passed through the membrane filter with electron microscopy and shadow casting technique.

Isolation and Partial Characterization of Carotenoid Pigments of Mycobacterium Rhodochrous

Isolation and Partial Characterization of Carotenoid Pigments of Mycobacterium Rhodochrous

Date: August 1971
Creator: Jorgensen, Joyce A.
Description: It was the purpose of this investigation to isolate and characterize the pigments of Mycobacterium rhodochrous by partition behavior, chromatographic data, and absorption spectra. In addition, it was the purpose to determine whether or not the type of pigments found in M. rhodochrous is typical of those found in other mycobacteria.

Isolation, Characterization and Physiological Studies of Cyanide-Utilizing Bacteria

Isolation, Characterization and Physiological Studies of Cyanide-Utilizing Bacteria

Date: December 1991
Creator: Silva Avalos, Juan G. (Juan Guillermo)
Description: Ten bacteria capable of growth on the metal-cyano complex, tetracyanonickelate (II) {K2 [Ni(CN)J } (TCN), supplied as the sole nitrogen source, were isolated. Seven isolates were identified as pseudomonads while the remaining three were classified as Klebsiella species. In addition to TCN, all isolates were able to utilize KCN although it was significantly more toxic. The degradation of TCN was most complete when supplied at growth-limiting concentrations, did not occur when ammonia was present, and resulted in the formation of nickel cyanide [Ni(CN)2] as a degradation product.

The Isolation, Cultivation and Testing of Organisms Anatagonistic to a Streptomycin Resistant Strain of Pseudomonas Aeruginosa

The Isolation, Cultivation and Testing of Organisms Anatagonistic to a Streptomycin Resistant Strain of Pseudomonas Aeruginosa

Date: 1951
Creator: Banister, Jack Warren
Description: The problem of finding an efficient antibiotic against Pseudomonas aeruginosa which can be used in the clinical treatment of genito-urinary tract infections resistant to treatment by streptomycin has not yet been solved. Therefore, this problem has consisted of first, the acquisition of possible inhibitors of the streptomycin resistant strain of Pseudomonas aeruginosa; second, the selection and identification of those which show a marked antagonism toward this organism; third, the determination of the antibiotic spectra of the inhibitors; fourth, the determination of whether the streptomycin resistant strain could also acquire a resistance to the antibiotic produced by its inhibitors; and last, an attempt to evaluate the therapeutic possibilities of the antibiotics demonstrated.

Isolation, Identification and Cultivation of Four Phytopathogenic Fungi

Isolation, Identification and Cultivation of Four Phytopathogenic Fungi

Date: 1951
Creator: Parks, Leroy W.
Description: This investigation includes a morphological and cultural study of four rather common pathogenic fungi one of which attacks Zinnia elegans, one Lagerstroemia indica, one Ligustrum lodense and one Euonymus japonica. The problem includes, first, a determination of the genera of these four fungi as revealed by their morphology in natural habitat; second, a determination of the growth and cultural characteristics of these on Cornmeal, Potato, Bean, Prune and Carrot agars; third, a comparison of the growth and cultural characteristics of these in natural habitat with the same on the various agars used; and fourth, an evaluation of the five artificial culture media in so far as their usage is concerned in the growth and cultivation of these four species of fungi.
