Denitrification is a distinct means of energy conservation, making use of N oxides as
terminal electron acceptors for cellular bioenergetics under anaerobic, microaerophilic, and …

Nitrogen is present in the environment in a number of oxidation states (Fig. 1).
Interconversion between these oxidation states is predominantly biological (Fig. 1). In this …

Wastewater treatment plants (WWTPs) are important sinks of microplastics (MPs) and
antibiotics resistance genes (ARGs). Information regarding connections between functional …

The inorganic nitrogen cycle (Figure 1) consists of several linked biological processes and
one abiological process, the reaction of N2 and O2 in lightning discharges and internal …

As an alternative to photosynthesis or aerobic respiration, many microbial species can
respire anaerobically to gain energy for cell growth. 1-4 A variety of bacteria employ a …

Copper-based catalysts are active in a wide range reactions of transformation of nitrogen
oxides and represent an useful model system to better understand the fundamental aspects …

Neurotrophins are secreted growth factors critical for the development and maintenance of
the vertebrate nervous system. Neurotrophins activate two types of cell surface receptors …

Nitric oxide (NO) is a poison, and organisms employ diverse systems to protect against its
harmful effects. InEscherichia coli, ygaA encodes a transcription regulator (b2709) …

At the end of the 19th century an experimental study had already reported N gas production
during microbial nitrate reduction, which significantly exceeded the amount of nitrate N …

Bacterial N oxide metabolism is related to cellular bioenergetics and processes of nitrogen
assimilation. The interest in nitric oxide (NO) centers around the dissimilatory transformation …
