Competitive and substrate limited environments drive metabolic heterogeneity for comammox Nitrospira

ISME Communications, 2023
Abstract Nitrospira has been revealed as a high versatile genus. Although previously considered only responsible for the conversion of nitrite to nitrate, now we know that Nitrospira can perform complete ammonia oxidation to nitrate too (comammox).

DNA- and RNA-SIP Reveal Nitrospira spp. as Key Drivers of Nitrification in Groundwater-Fed Biofilters

mBio, 2019
Nitrification, the oxidative process converting ammonia to nitrite and nitrate, is driven by microbes and plays a central role in the global nitrogen cycle.

Genomic Analysis of Two Phylogenetically Distinct Nitrospira Species Reveals Their Genomic Plasticity and Functional Diversity

Frontiers in Microbiology, 2018
The genus Nitrospira represents a dominant group of nitrite-oxidizing bacteria in natural and engineered ecosystems. This genus is phylogenetically divided into six lineages, for which vast phylogenetic and functional diversity has been revealed by ...

Metagenomic recovery of two distinct comammox Nitrospira from the terrestrial subsurface [PDF]

Environmental Microbiology, 2019
Summary The recently discovered comammox process encompasses both nitrification steps, the aerobic oxidation of ammonia and nitrite, in a single organism. All known comammox bacteria are affiliated with Nitrospira sublineage II and can be grouped into two distinct clades ...

Effects of Nitrogen Fertilizer on Nitrospira- and Nitrobacter-like Nitrite-Oxidizing Bacterial Microbial Communities under Mulched Fertigation System in Semi-Arid Area of Northeast China

Agronomy, 2023
The accumulation of nitrite is frequently overlooked, despite the fact that nitrification is the most essential phase of the entire nitrogen (N) cycle and that nitrifying bacteria play a significant role in nitrification.

Forecasting Root Rot Disease through Predictive Microbial Functional Profiling

Advanced Science, EarlyView.
Predicting soil‐borne disease moves beyond observation with a framework that elevates microbial functional genes into reliable forecasting biomarkers. By coupling targeted qPCR assays for core stress‐response genes with machine learning, this method detects root rot risks in pre‐symptomatic soils with over 80% accuracy.

Metagenomic approaches reveal differences in genetic diversity and relative abundance of nitrifying bacteria and archaea in contrasting soils

Scientific Reports, 2021
The abundance and phylogenetic diversity of functional genes involved in nitrification were assessed in Rothamsted field plots under contrasting management regimes—permanent bare fallow, grassland, and arable (wheat) cultivation maintained for more than ...

Inhibition of Targeted Bacterial Growth Using MazF‐Expressing Phagemids: A Novel Therapeutic Approach Based on Endoribonuclease Toxin Molecules

Microbiology and Immunology, EarlyView.
ABSTRACT The extensive and indiscriminate use of antibiotics, which are intended to halt bacterial growth or eliminate them, has unintentionally given rise to antimicrobial resistance (AMR), which is a critical threat to global health. In the pursuit of alternative solutions, researchers have focused on type II toxin–antitoxin systems prevalent within ...
