Redox reactions play important roles in almost all biological processes, including
photosynthesis and respiration, which are two essential energy processes that sustain all life …

Aerobic denitrification is a novel biological nitrogen removal technology, which has been
widely investigated as an alternative to the conventional denitrification and for its unique …

The limited information on microbial interactions and metabolic patterns in denitrification
systems, especially those fed with different carbon sources, has hindered the establishment …

Nitrate reduction to ammonia has attracted much attention for nitrate (NO3‐) removal and
ammonia (NH3) production. Identifying promising catalyst for active nitrate electroreduction …

Molybdenum is the only second-row transition metal required by most living organisms, and
is nearly universally distributed in biology. Enzymes containing molybdenum in their active …

Constructed wetland (CW) for wastewater treatment has attracted increasing attention. In this
review, the system configuration optimization, purification effect and general mechanisms of …

Microorganisms are able to utilize nitrogen (N) from a wide range of organic and mineral
compounds. In this paper, we review the current knowledge about the regulation of the …

Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on
alternative electron acceptors for respiration. Conditions therein enable an almost complete …

Dissimilatory sulphate reduction is the unifying and defining trait of sulphate-reducing
prokaryotes (SRP). In their predominant habitats, sulphate-rich marine sediments, SRP have …

Obligate methanotrophs belonging to the Phyla Proteobacteria and Verrucomicrobia require
