The anaerobic/aerobic/anoxic (A/O/A) process is a promising biotechnology to intensify
denitrification in low carbon/nitrogen (C/N) wastewater treatment, but the neglected typical …

Ammonia monooxygenase (AMO)-mediated cometabolism of organic pollutants has been
widely observed in biological nitrogen removal process. However, its molecular mechanism …

The two evolutionarily unrelated nitric oxide-producing nitrite reductases, NirK and NirS, are
best known for their redundant role in denitrification. They are also often found in organisms …

Ammonia oxidation, as the first step of nitrification, constitutes a critical process in the global
nitrogen cycle. However, fundamental knowledge of its key enzyme, the copper-dependent …

Panax ginseng, a prized medicinal herb, has faced increasingly challenging field production
due to soil degradation and fungal diseases in Northeast China. Wild-simulated cultivation …

Monooxygenase (MO) enzymes are responsible for the oxidation of hydrocarbons and other
compounds in the carbon and nitrogen cycles, are important for the biodegradation of …

Temporal variation in community composition is central to our understanding of the
assembly and functioning of microbial communities, yet the controls over temporal dynamics …

Partial organic substitution (POS) is pivotal in enhancing soil productivity and changing
nitrous oxide (N 2 O) emissions by profoundly altering soil nitrogen (N) cycling, where …

Long-term deposition of atmospheric pollutants emitted from coal combustion and their
effects on the eco-environment have been extensively studied around coal-fired power …

Background Permanently stratified lakes contain diverse microbial communities that vary
with depth and so serve as useful models for studying the relationships between microbial …
