Coexistence of nitrifying, anammox and denitrifying bacteria in a sequencing batch reactor
Frontiers in Microbiology, 2014 Elevated nitrogen removal efficiencies from ammonium-rich wastewaters have been demonstrated by several applications, that combine nitritation and anammox processes. Denitrification will occur simultaneously when organic carbon is also present.

Toxic Response of Nitrobacter to Orange II and Direct Blue 71
Journal of Applied Sciences and Environmental Management, 2004 Tolerance of Nitrobacter to Orange II (C.L. 15510) and Direct Blue 71 (C.I. 34140) dyes was determined by total viable count. There was decrease in percentage log survival with increase in concentration of the toxicants and increase in exposure time ...

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 2, June 2025.ABSTRACT Livestock farming and its slurry management represent a significant contributor to global anthropogenic ammonia (NH3) and greenhouse gas (GHG) emissions, resulting in negative impacts on the environment. The aim of this study was to evaluate the effect of two microbial slurry additives (A1, A2) on the emissions of NH3, methane (CH4) and carbon

Detection and counting of Nitrobacter populations in soil by PCR [PDF]
Applied and Environmental Microbiology, 1995 Although the biological conversion of nitrite to nitrate is a well-known process, studies of Nitrobacter populations are hindered by their physiological characteristics. This report describes a new method for detecting and counting Nitrobacter populations in situ with the PCR.

Oxidation kinetics and inverse isotope effect of marine nitrite-oxidizing isolates [PDF]
, 2017 Nitrification, the step-wise oxidation of ammonium to nitrite and nitrate, is important in the marine environment because it produces nitrate, the most abundant marine dissolved inorganic nitrogen (DIN) component and N-source for phytoplankton and ...
