The Role Of D-Gluconic Acid In The Regulation Of The Synthesis Of The Enzymes Of The Entner-Doudoroff Pathway In Pseudomonas Fluorescens, Steven C. Quay Aug 1971

The Role Of D-Gluconic Acid In The Regulation Of The Synthesis Of The Enzymes Of The Entner-Doudoroff Pathway In Pseudomonas Fluorescens, Steven C. Quay

Honors Theses

Induction of Entner-Duodoroff pathway enzymes in Pseudomonas fluorescens was investigated to study the role of gluconate as a possible inducer. Glucose oxidase-deficient mutants were isolated and characterized. One of these mutants, gox-7, was deficient in particulate glucose oxidase; another mutant, gox-17, was deficient in particulate glucose and gluconate oxidase activities. Gluconate, but not glucose, induced synthesis of gluconokinase and 6-phosphogluconate dehydratase in both mutants. High constitute levels of 2-keto-3-deoxy-6-phosphogluconate aldolase were found when both mutants were grown on glucose. Growth of parent and both mutant strains on glycerol also resulted in high levels of Entner-Doudoroff pathway enzymes. It was concluded …

A Study Of The Bacteriological Effectiveness Of Oral Thermometer Procedures In Three Selected Hospitals, Esther Mae Rose May 1961

A Study Of The Bacteriological Effectiveness Of Oral Thermometer Procedures In Three Selected Hospitals, Esther Mae Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Because pathogens such as streptococcus and staphylococcus have been transferred in many hospitals, the source of the infections is of concern to doctors, nurses, and other medical personnel. As shown by the review of literature, good techniques are necessary to stop the spread of disease.

It was the purpose of this study to investigate one facet of patient safety by: (1) the culture of thermometers ready for use in three selected hospitals; (2) to determine the effectiveness of the Group, Individual, and Central Supply methods of disinfection currently practiced in the three selected hospitals.

The method for the experiment of …
