Enzymatic versus nonenzymatic denitrification

Creator:: Bulla, Lee A.
Abstract:: Denitrification is classically defined as the microbial reduction of nitrate and nitrite with the liberation of molecular nitrogen and, in some instances, nitrous oxide. The sequence of reactions in which nitrogen is evolved as an end-product is essentially a respiratory mechanism in which nitrate and/or nitrite replaces molecular oxygen. The...

Phosphorus metabolism in Pseudomonas stutzeri

Creator:: Elliott, Lloyd Floren
Abstract:: The role of nitrate oxygen as a terminal acceptor of hydrogen stands as a unique form of bacterial respiration. As nitrate is reduced to nitrite on to the gaseous state (N₂, N₂O) the substrate is oxidized to give the requisite energy for cell growth. The present study will deal with...

The comparative role of molecular and nitrate-oxygen in the dissimilation of glucose

Creator:: Bhatt, Rajanikant Premshanker
Abstract:: When nitrate is used in a biological electron transport system as the final acceptor of hydrogen to form water, the system is characterized as "Nitrate Respiration." However, the quantitative expression of the over-all participation of NO₃⁻(0) in the oxidation of glucose by denitrifiers such as Pseudomonas stutzeri deserves clarification. In...

Transcriptome profiling of Nitrosomonas europaea grown singly and in co-culture with Nitrobacter winogradskyi

Creator:: Pérez, José
Abstract:: In most environments, ammonia (NH₃) is oxidized to nitrate (NO₃⁻) via the intermediate nitrite (NO₂⁻). This is a microbe-driven process involving phylogenetically distinct types of microorganisms, namely, ammonia-oxidizing bacteria (AOB) and Thaumarchaea (AOA), and nitrite-oxidizing bacteria (NOB). Nitrosomonas europaea and Nitrobacter winogradskyi are the best studied AOB and NOB, respectively,...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...

An investigation of carbon and nitrogen metabolism through a genomic analysis of the genus Nitrobacter

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...
