Abstract

Little is known concerning the physiology of obligate microaerophiles. This thesis describes research aimed at furthering our understanding of the obligately microaerophilic nature of the magnetic diazotrophic denitrifier, Aquaspirillum magnetotacticum. Included are studies of iron respiration-driven proton translocation, of microaerobic denitrification and associated NO$\sbsp{2}{-}$ toxicity, and of expression and cellular location of O$\sb2$ detoxifying enzymes in this organism.
