Comparison of degradation kinetics of tannery wastewater treatment using a nonlinear model by salt-tolerant Nitrosomonas sp. and Nitrobacter sp.

Bioresource Technology, 2022
Conventional biological treatment has been reported to be ineffective for pollutant removal in tannery wastewater due to high salinity. To overcome it, this work used salt-tolerant bacteria (STB) isolated from a membrane bioreactor to evaluate the ...

Plasmids in Nitrobacter

Archives of Microbiology, 1984
A screening of nine Nitrobacter strains showed that Nitrobacter X14 and Nitrobacter Y possess plasmids designated as pNH1 and pNH2, respectively. The plasmids pNH1 and pNH2 had molecular weights of about 76 Mdal as estimated by agarose gel electrophoresis. They showed similar cleavage patterns when digested with EcoRI, HindIII or BamHI.

Oxidative phosphorylation in Nitrobacter winogradskyi

Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1965
Summary A crude cell-free extract from Nitrobacter winogradskyi , which esterified inorganic phosphate in the course of oxidizing nitrite, had a P/O ratio of 0.17. Only fairly coarse particles were found to exhibit P/O ratios larger than 0.1.

Formate utilization by Nitrobacter wibogradskyi

Biochimica et Biophysica Acta (BBA) - General Subjects, 1966
Abstract 1. 1. Formate is actively oxidized by Nitrobacter winogradskyi. The pH that is optimal for formate oxidation is different from the optimum pH for nitrite oxidation 2. 2. The same respiratory chain is used between cytochrome c and oxygen for nitrite and formate oxidation. 3. 3. Energy from formate oxidation is used to CO2 fixation

Particulate formate oxidase from Nitrobacter agilis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1970
Abstract 1. The nitrite oxidase particles obtained by sonic oscillation of Nitrobacter agilis cells also possessed appreciable formate oxidase activity, ranging from about 25 to 50% of the nitrite oxidase activity depending upon the N. agilis strain.

Kinetic and Physiological Characterization of Acidophilic Nitrobacter spp. in a Nitrite-Oxidizing Culture.

Environmental Science and Technology
Novel acidophilic nitrite-oxidizing Nitrobacter spp. were enriched, with kinetic and physiological features characterized comprehensively. The acidophilic Nitrobacter enrichment culture was cultivated in a membrane bioreactor at pH 4.6-5.5 for 500 days ...

Exogenous Respiration in Nitrobacter

Nature, 1960
DURING the course of an investigation of the oxidation of nitrite by the nitrite-oxidizing bacterium, Nitrobacter, it was noted that the addition of sodium nitrite but not sodium nitrate to heavy cell suspensions caused the immediate appearance of reduced cytochrome bands at 590, 551 and 513 mµ when viewed in the hand spectroscope1.

Nitrate leaching from soil under different forest tree species is related to the vertical distribution of Nitrobacter abundance.

Science of the Total Environment
Forest tree species and their mineral N uptake strategies can influence the activity and abundance of nitrifying microorganisms in deeper soil layers and subsequent nitrate leaching.
