Controls and Adaptive Management of Nitrification in Agricultural Soils

Frontiers in Microbiology, 2019
Agriculture is responsible for over half of the input of reactive nitrogen (N) to terrestrial systems; however improving N availability remains the primary management technique to increase crop yields in most regions.

Potential Role of Fungal Endophytes in Biological Nitrification Inhibition in Brachiaria Grass Species [PDF]

Journal of Plant Biochemistry & Physiology, 2017
Brachiaria species have the ability to suppress nitrification in soil by releasing an inhibitory compound called ‘brachialactone’ from its roots; a process termed biological nitrification inhibition (BNI). This study tested the hypothesis that endophytic association with Brachiaria grass improves BNI activity of root tissues and reduces ...

Biological inhibition of soil nitrification by forest tree species affects Nitrobacter populations

Environmental Microbiology, 2020
Summary Some temperate tree species are associated with very low soil nitrification rates, with important implications for forest N dynamics, presumably due to their potential for biological nitrification inhibition (BNI).

Nitrosospira cluster 3 lineage of AOB and nirK of Rhizobiales respectively dominated N2O emissions from nitrification and denitrification in organic and chemical N fertilizer treated soils

Ecological Indicators, 2021
Agricultural soils are known as nitrous oxide (N2O) sources due to the input of nitrogen (N) fertilizer and livestock faecal excretion. However, few studies have explored the responses of N2O microbial emission pathways and their related functional ...

Combined effect of heavy metals on the activated sludge process; pp. 305–314 [PDF]

Proceedings of the Estonian Academy of Sciences, 2018
Migration of heavy metals in the environment is a serious problem for wastewater treatment plants (WWTP) and the environment as a whole. The combined effect of eight heavy metals on the biological wastewater treatment process was analysed in this ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Biological nitrification inhibition (BNI)-Is there potential for genetic interventions in the Triticeae?

Breeding Science, 2009
The natural ability of plants to release chemical substances from their roots that have a suppressing effect on nitrifier activity and soil nitrification, is termed ‘biological nitrification inhibition’ (BNI). Though nitrification is one of the critical processes in the nitrogen cycle, unrestricted and rapid nitrification in agricultural systems can ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Molecular biological methods (DGGE) as a tool to investigate nitrification inhibition in wastewater treatment

Water Science and Technology, 2003
Incomplete nitrification at an activated sludge plant for biological pre-treatment of rendering plant effluents led to a detailed investigation on the origin and solution of this problem. Preliminary studies revealed that an inhibition of ammonia oxidising microorganisms (AOM) by process waters of the rendering plant was responsible for the situation ...
