New facultative lithoautotrophic nitrite-oxidizing bacteria
Archives of Microbiology, 1983A nitrite-oxidizing bacterium was isolated from soil of the Old Botanic Garden in Hamburg and of a cornfield near Uxmal in Yucatan (Mexico). The cells are 0.5–0.8 ×1.2–2.0 μm in size, pleomorphic, mostly pear-shaped and motile by means of one subpolar to lateral flagellum. Intracytoplasmic membranes are present as caps of flattened vesicles or membrane

In a pot-cultural experiment, the impact of the antibiotic roxithromycin (ROX) addition was assessed on the diversities of microbial structure and function communities, especially involved in ammonia and nitrite oxidation in wheat rhizosphere soil with and without the addition of earthworms.

Diversity, Environmental Genomics, and Ecophysiology of Nitrite-Oxidizing Bacteria
2011A comprehensive biological understanding of nitrite-oxidizing bacteria (NOB) will be important to improve the functional stability of wastewater treatment systems and to reduce detrimental effects of nitrification in agriculture. The first part of this chapter provides an overview of the phylogenetic diversity and distribution of NOB in the environment

Factors affecting the growth rates of ammonium and nitrite oxidizing bacteria
Chemosphere, 2011The maximum specific growth rates of both ammonium oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) were investigated under varying aerobic solids retention time (SRT(a)) and in the presence/absence of anoxic (alternating) conditions. Two bench SBRs, reactor R1 and R2, were run in parallel for 150d.

Immobilization of nitrite oxidizing bacteria using biopolymeric chitosan media
Journal of Environmental Sciences, 2013The effects of chitosan characteristics including the degree of deacetylation, molecular weight, particle size, pH pretreatment and immobilization time on the immobilization of nitrite-oxidizing bacteria (NOB) on biopolymeric chitosan were investigated. Nitrite removal efficiency of immobilized NOB depended on the degree of deacetylation, particle size,

Nitrite-oxidizing Bacteria: Cultivation, Growth Physiology, and Chemotaxonomy
2023Nitrification is a microbial process that converts ammonia and similar nitrogen compounds into nitrite (NO2−) and then nitrate (NO3−) via two different functional groups of specialized chemolithoautotrophic microorganisms. In an oxygenic environment, nitrification occurs in rivers, lakes, aerated soil, ocean water, sediments, and biological wastewater ...

Cultivation, Growth Physiology, and Chemotaxonomy of Nitrite-Oxidizing Bacteria
2011Lithoautotrophic nitrite-oxidizing bacteria (NOB) are known as fastidious microorganisms, which are hard to maintain and not many groups are trained to keep them in culture. They convert nitrite stoichiometrically to nitrate and growth is slow due to the poor energy balance.

Temperature influences the population structure of nitrite‐oxidizing bacteria in activated sludge
Environmental Microbiology Reports, 2009Summary Activated sludge from the municipal waste water treatment plant in Hamburg was seeded with mineral nitrite medium and incubated at 10°C, 17°C and 28°C. Dominant lithoautotrophic nitrite‐oxidizing bacteria have been identified by electron microscopy, denaturing and temperature gradient gel electrophoresis ...

The number of nitrite-oxiding bacteria in soil percolated with nitrite
Soil Science and Plant Nutrition, 1971Abstract Quastel and Scholefield (1) observed that soils, after a preliminary percolation with nitrite, oxidized nitrite at a constant rate without a lag period. Oxidation of ammonium exhibited similar kinetics. Such soils were regarded as being saturated with nitrite-oxidizing bacteria.

NO2 Sensor which uses immobilized nitrite oxidizing bacteria
Biotechnology and Bioengineering, 1983AbstractA biosensor consisting of immobilized nitrite oxidizing bacteria and an oxygen electrode has been developed for the amperometric determination of NO2 (nitrogen dioxide) gas. The response time for the determination of NO2 was within 3 min. A linear relationship was observed between the current decrease and the NO2 concentration below 255 ppm ...
