Cell Envelope Constituents Of Pseudomonas Putida Contributing To Growth And Survival In Low-Water-Content Habitats , Martinus Franciscus Maria Van De Mortel

Retrospective Theses and Dissertations

The ability of bacteria to respond to the ever changing environmental conditions they encounter requires the utilization of a broad range of colonization and survival strategies. One of the most important and probably least understood factors determining bacterial activity in terrestrial habitats is water availability. The goal of this dissertation research was to identify traits that contribute to maintaining a functional cell envelope when cells are dehydrated, which will help us to assess the scope of physiological changes necessary for growth in low-water-content habitats. The primary objective was to identify genes that are specifically regulated by dehydration (matric stress), and ...


Bacterial Physiology And Enzymology Of The Membrane-Associated Methane Monooxygenase And Ammonia Oxidation System From Methylococcus Capsulatus Bath, 1992-1996 , James Allan Zahn Jan 1996

Bacterial Physiology And Enzymology Of The Membrane-Associated Methane Monooxygenase And Ammonia Oxidation System From Methylococcus Capsulatus Bath, 1992-1996 , James Allan Zahn

Retrospective Theses and Dissertations

The enzymology and microbial physiology of methane and ammonia oxidation by the membrane-associated methane monooxygenase (pMMO) from the obligate methylotroph, Methylococcus capsulatus Bath were studied. Conditions leading to the stabilization of the pMMO were defined, and an active preparation of the pMMO from M. capsulatus Bath was isolated by ion exchange and hydrophobic interaction chromatography using dodecyl-[beta]-D-maltoside as the detergent. The active preparation consisted of three major polypeptides with molecular masses of 47,000 and 27,000, and 25,000 Da and contained 2.5 iron and 14.5 copper atoms per mole of enzyme. The 27,000 ...
