Many biotechnological applications deal with nitrification, one of the main steps of the global
nitrogen cycle. The biological oxidation of ammonia to nitrite and further to nitrate is critical to …

Nitrification is a key process of the biogeochemical nitrogen cycle and of biological
wastewater treatment. The second step, nitrite oxidation to nitrate, is catalyzed by …

Oxidation of nitrite to nitrate is an important process in the global nitrogen cycle. Recent
molecular biology‐based studies have revealed that the widespread nitrite‐oxidizing …

Nitrification is a key process of the biogeochemical nitrogen cycle and of biological
wastewater treatment. The second step, nitrite oxidation to nitrate, is catalyzed by …

Nitrification is a key process for N-removal in engineered and natural environments, but
recent findings of novel nitrifying microorganisms with surprising features revealed that our …

In this work the question was addressed if in nitrite‐oxidizing activated sludge systems the
environmental competition between Nitrobacter spp. and Nitrospira spp., which only recently …

In this study, the microbial community of nitrifying activated sludge adapted to Finnish
climate conditions was studied to clarify the microbial populations involved in low …

Oxidation of nitrite to nitrate is an essential process in wastewater treatment systems.
Previous culturing studies have revealed that a new nitrite-oxidizing Candidatus Nitrotoga …

Numerous past studies have shown members of the genus Nitrospira to be the predominant
nitrite-oxidizing bacteria (NOB) in nitrifying wastewater treatment plants (WWTPs). Only …

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 …
