Book ChapterDOI
Autotrophic nitrification in bacteria
TL;DR: The chapter describes the basic features of the biochemistry of ammonia and nitrite oxidation and discusses the growth limiting factors and activity of these organisms.
Journal ArticleDOI
Completely autotrophic nitrogen removal over nitrite in one single reactor
A. Olav Sliekers,N Derwort,J L Campos Gomez,Marc Strous,Marc Strous,J.G. Kuenen,Mike S. M. Jetten,Mike S. M. Jetten +7 more
TL;DR: The microbiology and the feasibility of a new, single-stage, reactor for completely autotrophic ammonia removal were investigated and showed that during steady state, anaerobic ammonium-oxidizing bacteria remained present and active.
Journal ArticleDOI
Microbial nitrogen cycling processes in oxygen minimum zones.
Phyllis Lam,Marcel M. M. Kuypers +1 more
TL;DR: Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on alternative electron acceptors for respiration, and conditions therein enable an almost complete nitrogen (N) cycle and substantial N-loss.
Journal ArticleDOI
New concepts of microbial treatment processes for the nitrogen removal in wastewater
Ingo Schmidt,Olav Sliekers,Markus Schmid,Eberhard Bock,John A. Fuerst,J. Gijs Kuenen,Mike S. M. Jetten,Marc Strous +7 more
TL;DR: These processes target the removal of ammonia from gases, and ammonium-bicarbonate from concentrated wastewaters (i.e. sludge liquor and landfill leachate) and the microbiology, its consequences for their application, the current status regarding application, and the future developments are addressed.
Journal ArticleDOI
Evolutionary relationships among ammonia- and nitrite-oxidizing bacteria.
Andreas P Teske,Elizabeth Wheeler Alm,John M. Regan,Simon Toze,Bruce E. Rittmann,David A. Stahl +5 more
TL;DR: The nitrifiers, as a group, apparently are not derived from an ancestral nitrifying phenotype, and consideration of physiology and phylogenetic distribution suggested that nitrite-oxidizing bacteria of the alpha and gamma subdivisions are derived from immediate photosynthetic ancestry.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.
Journal ArticleDOI
Competition in denitrification systems affecting reduction rate and accumulation of nitrite
TL;DR: In this article, a mathematical model was developed, and experiments were conducted to study results of enhanced proliferation of facultative anaerobes, on the expense of true denitrifiers, in activated sludge biocommunities.
Journal ArticleDOI
Acetate Assimilation by Nitrobacter agilis in Relation to Its “Obligate Autotrophy”
Arnold J. Smith,Derek S. Hoare +1 more
TL;DR: Nitrobacter agilis is not an obligate autotrophic; it appears to be a facultative autotroph which resembles the novel facultative Autotroph, Thiobacillus intermedius, very closely.
Journal ArticleDOI
Growth of Nitrobacter by dissimilatoric nitrate reduction
TL;DR: Eight strains of the genus Nitrobacter grew under anaerobic conditions in the presence of nitrate in gas tight culture flasks as a biofilm on a gas-permeable silicone tubing, and produced nitrite and ammonia.
Journal ArticleDOI
Membrane-bound nitrite oxidoreductase of Nitrobacter: evidence for a nitrate reductase system
TL;DR: Nitrite oxidoreductase, the essential enzyme complex of nitrite oxidizing membranes, was isolated from cells of the nitrifying bacterium Nitrobacter hamburgensis and exhibited nitrate reductase activity with an apparent Km value of 0.9 mM for nitrate.
