Functional redundancy and niche complementarity maintain nitrification stability in rapid sand filters

Frontiers in Microbiology
Nitrification in drinking water biofilters is mediated by a complex guild of ammonia oxidizers, yet the mechanisms facilitating the coexistence of these functionally redundant nitrifier guild members are not well understood.

Temporal enrichment of comammox Nitrospira and Ca. Nitrosocosmicus in a coastal plastisphere

The ISME Journal
Abstract Plastic marine debris is known to harbor a unique microbiome (termed the “plastisphere”) that can be important in marine biogeochemical cycles. However, the temporal dynamics in the plastisphere and their implications for marine biogeochemistry remain poorly understood.

Regulatory Mechanisms of Exogenous Acyl-Homoserine Lactones in the Aerobic Ammonia Oxidation Process Under Stress Conditions

Microorganisms
This study investigated the mechanism by which N-acyl-homoserine lactone (AHL) signaling molecules influence ammonia-oxidizing microorganisms (AOMs) under inhibitory conditions.

Unveiling unique microbial nitrogen cycling and nitrification driver in coastal Antarctica

Nature Communications
Largely removed from anthropogenic delivery of nitrogen (N), Antarctica has notably low levels of nitrogen. Though our understanding of biological sources of ammonia have been elucidated, the microbial drivers of nitrate (NO3 −) cycling in coastal ...

Dominance of comammox Nitrospira in soil nitrification

Science of the Total Environment, 2021
The first and limiting step of nitrification is catalyzed by ammonia-oxidizing archaea (AOA) and bacteria (AOB). Recently, complete ammonia oxidizers (comammox Nitrospira) have been discovered to perform complete nitrification in one cell, yet their role in soil nitrification is still unclear.

In-situ expressions of comammox Nitrospira along the Yangtze River

Water Research, 2021
The recent discovery of comammox Nitrospira as complete nitrifiers has significantly enriched our understanding on the nitrogen cycle, yet little is known about their metabolic transcripts in natural aquatic ecosystems. Using the genome-centric metatranscriptomics, we provided the first in-situ expression patterns of comammox Nitrospira along the ...
