Abstract Five strains of lithotrophic, nitrite-oxidizing bacteria (AN1-AN5) were isolated from sediments of three soda lakes (Kunkur Steppe, Siberia; Crater Lake and Lake Nakuru, Kenya) and from a soda soil (Kunkur Steppe, Siberia) after enrichment at pH 10 with nitrite as sole electron source. Morphologically, the isolates resembled representatives of the genus Nitrobacter. However, they differed from recognized species of this genus by the presence of an additional S-layer in their cell wall… 
Introducing a novel facultative nitrifying bacterium, "Nitrobacteria hamadaniensis"
TLDR
According to the phylogenetic analysis and phenotypic criteria, it is proposed that the nitrifying bacterium should be assigned to a new genusNitrobacteria.
A New Facultative Chemolithotrophic Nitrifying Bacteria: Nitrobacter iranicum sp .v Nov.
TLDR
A Gram-negative, Oxidizing bacterium isolated from soil of a Potato field in Hamadan,Iran was described as a new species of the genus Nitrobacteria, N.iranicum on the basis of their substantial morphological, physiological and genetic differences.
Halomonas campisalis, an Obligatorily Alkaliphilic, Nitrous Oxide–Reducing Denitrifier with a Molybdenum Cofactor–Lacking Nitrate Reductase
TLDR
The culture isolated by us was characterized by peculiar properties, such as obligate alkaliphily, which manifested itself in the culture dependence on carbonates and lack of growth at pH values below 7, a nitrous oxide–reducing capacity, and an unusual nitrate reductase that lacked moly bdenum and a molybdenum cofactor.
Isolation and properties of obligately chemolithoautotrophic and extremely alkali-tolerant ammonia-oxidizing bacteria from Mongolian soda lakes
TLDR
Five isolates of ammonia-oxidizing bacteria capable of growth at pH 10 were obtained and demonstrated that they possess identical 16S rDNA genes and that they are closely related to Nitrosomonas halophila, a member of the β-subclass of the Proteobacteria.
Improved isolation strategies allowed the phenotypic differentiation of two Nitrospira strains from widespread phylogenetic lineages.
TLDR
Phylogenetic classification of 12 additional enrichments indicated that Nitrospira lineage I is common in extreme and moderate ecosystems like lineage II, and new cultures will help to explore physiological and genomic differences affecting niche separation between members of this highly diverse genus.
Ammonia stimulates growth and nitrite-oxidizing activity of Nitrobacter winogradskyi
TLDR
The aim of this study was to obtain a nitrite-oxidizing bacterium with high nitrite oxidation activity for controlling nitrite levels and the strain identified as Nitrobacter winogradskyi, which was isolated from the water of a coastal Pseudosciaena crocea-rearing pond.
Enrichment and Physiological Characterization of a Cold-Adapted Nitrite-Oxidizing Nitrotoga sp. from an Eelgrass Sediment
TLDR
The laboratory experiments showed that the Nitrotoga enrichment culture could adapt not only to low temperature but also to relatively high concentrations of free ammonia, which helps improve the comprehension of the functional importance of Nitrotogo.
Anaerobic growth of the haloalkaliphilic denitrifying sulfur-oxidizing bacterium Thialkalivibrio thiocyanodenitrificans sp. nov. with thiocyanate.
TLDR
Two strains of obligate chemolithoautotrophic sulfur-oxidizing bacteria were isolated from soda-lake sediments by enrichment culture with thiocyanate and nitrate and are described as a novel species of the genus Thialkalivibrio, with the highest similarity to Thialcyanodenitrificans.
Thioalkalimicrobium cyclicum sp. nov. and Thioalkalivibrio jannaschii sp. nov., novel species of haloalkaliphilic, obligately chemolithoautotrophic sulfur-oxidizing bacteria from hypersaline alkaline Mono Lake (California).
TLDR
Two strains of haloalkaliphilic, obligately autotrophic, sulfur-oxidizing bacteria were isolated from the oxygen-sulfide interface water layer of stratified alkaline and saline Mono Lake, California, USA and genetic comparison and phylogenetic analysis suggested that ALM 1T represents a new species of the genus Thioalkalimicrobium in the gamma-Proteobacteria.

An Acidophilic and a Neutrophilic Nitrobacter Strain Isolated from the Numerically Predominant Nitrite-Oxidizing Population of an Acid Forest Soil
TLDR
Isolation of the neutrophilic Nitrobacter strain reported here complements the earlier isolation of a neutrophobic Nitrosospira strain to provide further evidence of a prominent acid-intolerant population of chemoautotrophic nitrifiers in this acid forest soil.
Increased species diversity and extended habitat range of sulfur-oxidizing Thiomicrospira spp
TLDR
An increased species diversity of Thiomicrospira and the ubiquity of this sulfur-oxidizing bacterium in habitats with reduced sulfur compounds are indicated.
Nitrification at Low pH by Aggregated Chemolithotrophic Bacteria
TLDR
Nitrification by aggregated chemolithoautotrophic bacteria may be the dominating process of nitrate formation in many acid soils as it does not appear to depend on the existence of microsites of high pH (acid-sensitive autotrophic nitrification) or on the availability of organic carbon (heterotrophicNitrification).
Genomic heterogeneity of the genus Nitrobacter
The genomic diversity among 22 Nitrobacter strains was investigated by determining rRNA gene restriction patterns, DNA hybridization characteristics, and DNA base compositions. The
Activity of chemolithotrophic nitrifying bacteria under stress in natural soils
TLDR
According to Bergey’s Manual of Systematic Bacteriology, the family of nitrifying bacteria is a diverse group of rods, vibrios, cocci, and spirilla, all having the ability to utilize ammonia or nitrite as a major source of energy and carbon dioxide as the chief source of carbon.
Kinetics of nitrite oxidation by Nitrobacter winogradskyi.
TLDR
The present observations complete and extend the results concerning the effects of pH, concentrations of nitrite and of nitrate, temperature and oxygen partial pressure on the parameters of the rate equation for the oxidation of nitrites by intact cells and cell-free extracts.
The nitrite oxidizing system of Nitrobacter winogradskyi.
TLDR
A flavoenzyme has been obtained which has transhydrogenase activity and catalyses reduction of NADP+ with benzylviologen radical and this enzyme may be responsible for production of NADPH in N. winogradskyi.

TLDR
Deep wastewater reservoirs used throughout Israel to store domestic wastewater effluents are found to be capable of sustaining a viable, although not actively nitrifying, population of Nitrosomonas spp.
The Wadi Natrun: Chemical composition and microbial mass developments in alkaline brines of Eutrophic Desert Lakes
Six lakes of the Wadi Natrun, Egypt, were studied with respect to the chemical composition of their brines and the occurrence of microbial mass developments. All investigated lakes showed pH values
How close is close: 16S rRNA sequence identity may not be sufficient to guarantee species identity.
TLDR
Although 16S rRNA sequences can be used routinely to distinguish and establish relationships between genera and well-resolved species, very recently diverged species may not be recognizable.
