A study of the lipids of Pseudomonas aeruginosa sensitive and resistant to chloramphenicol and quaternary ammonium compound

Creator:: Anderes, Eugene Armin
Abstract:: From a population of cells of Pseudomonas aeruginosa sensitive 33 parts per million (ppm) and 0.1 mg per ml of quaternary ammonium (QAC) and chloramphenicol respectively, pure strains resistant to 750 ppm and 50 mg per ml of these antibiotics were isolated. Lipids from the sensitive and resistant cells grown...

Hydrogen peroxide oxidation of annual ryegrass lignin and utilization of the products by Rhodotorula mucilaginosa

Creator:: Rockhill, Robert Clayton
Abstract:: Annual ryegrass (Lolium multiflorum) a major grass seed crop in the Willamette Valley, Oregon, is presently burned in the fields after harvest, causing considerable air pollution and general wastage of a material which could be used in the manufacture of economically important products. The cellulosic component of straw is relatively...

Isolation and characteristics of the DNA from nuclear polyhedrosis virus

Creator:: Carnegie, John William
Abstract:: The genome of the nuclear polyhedrosis virus which infects the larvae of the tussock moth, the lepidopteran, Hemerocampa pseudotsugata, was isolated, identified as deoxyribonucleic acid, and characterized in terms of its physical and biological properties. An isolation procedure for the viral DNA was established which consisted of the following steps:...

The association of DNA with other cellular materials in Escherichia coli lysates

Creator:: Porter, Bruce Wallace
Abstract:: The association of other materials with DNA has been studied extensively in higher organisms and more recently in bacteria. However, investigation of these complexes in bacteria have for the most part been restricted to the study of a specific function this association may serve, or a specific kind of association....

Transmission of disseminated neoplasia in the soft shell clam, Mya arenaria

Creator:: House, Marcia
Abstract:: Disseminated neoplasia (DN) is a proliferative cell disorder that occurs in the circulatory system of bivalves. The condition is progressive and lethal. At least 15 species of bivalves over a wide range of geographic locations have been reported to contract DN. Prevalence levels of disseminated neoplasia can reach up to...

Isolation and characterization of a leukocytolytic factor from Aeromonas salmonicida

Creator:: Fuller, David Wallace
Abstract:: The purpose of this study was to find what effect temperature and immunization has on the phagocytic activity of fish leukocytes against certain disease causing bacteria. Also proposed was the isolation and characterization of a leukocytolytic factor produced by one of these bacteria, Aeromonas salmonicida. Investigations revealed that temperature had...

Incidence and significance of bacterial chitinase in the marine environment

Creator:: Goodrich, Thomas Dale
Abstract:: The marine vibrio ANT-500 is a typical psychrophile. The growth range of the bacterium at 35‰ S is from a maximum growth temperature of 13.5 C to a minimum growth temperature of -2.5 C or less with the optimum near 7 C. The bacterium elaborates its chitinase enzymes between the...

Distribution of Clostridium botulinum type E in fish, shellfish and the marine environment of the Pacific Northwest, and protein patterns of the toxigenic and non-toxigenic stains

Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...
