Inhibition of bacterial ammonia oxidation by organohydrazines in soil microcosms

Frontiers in Microbiology, 2012
Hydroxylamine oxidation by hydroxylamine oxidoreductase (HAO) is a key step for energy-yielding in support of the growth of ammonia-oxidizing bacteria (AOB).

Comparative analysis of ammonia monooxygenase (amoA) genes in the water column and sediment-water interface of two lakes and the Baltic Sea [PDF]

, 2008
The functional gene amoA was used to compare the diversity of ammonia-oxidizing bacteria (AOB) in the water column and sediment-water interface of the two freshwater lakes Plusssee and Schöhsee and the Baltic Sea.

Exploring variations in potential carbon and nitrogen mineralization in managed grasslands among the diversity of soils in North Carolina

Grassland Research, EarlyView.
Under steady–state conditions, potential nitrogen mineralization in soil under grasslands is closely tied to potential carbon mineralization. This study provides supporting evidence that field–specific nitrogen fertilizer recommendations could be indicated by using a simple and rapid analysis of soil–test biological activity.

Ammonia oxidizing archaea and bacteria respond to different manure application rates during organic vegetable cultivation in Northwest China

Scientific Reports, 2023
Ammonia oxidization is a critical process in nitrogen cycling that involves ammonia oxidizing archaea (AOA) and bacteria (AOB). However, the effects of different manure amounts on ammonia-oxidizing microorganisms (AOMs) over the course of organic ...

Ratio of natural isotopes of nitrogen. I. Primary results: soils of Dombes [Translation from: Revue d'Ecologie et de Biologie du Sol 14, 279-287, 1977] [PDF]

, 1980
Utilization of the heavy isotope of nitrogen as a tracer has found numerous applications in soil biology. It allows better definition of different stages of the nitrogen cycle, in particular the immobilization-mineralization cycle.

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Evaluation of polyurethane sponge biocarrier effects on Litopenaeus vannamei cultivation in zero water exchange systems based on water quality, shrimp performance and bacterial community analysis

Frontiers in Environmental Science, 2023
To evaluate the effects of polyurethane sponge biocarriers with precultured biofilms (PSBF) on water quality, shrimp performance and bacterial communities, zero water exchange systems for Litopenaeus vannamei were constructed. The experiment consisted of

Structure of the Nitrosomonas europaea Rh protein [PDF]

Proceedings of the National Academy of Sciences, 2007
Amt/MEP/Rh proteins are a family of integral membrane proteins implicated in the transport of NH 3 , CH 2 NH 2 , and CO 2 . Whereas Amt/MEP proteins are agreed to transport ammonia (NH 3 /NH 4 +
