Nitrogenase, the enzyme that catalyses biological nitrogen fixation, is oxygen sensitive and requires ATP and an electron donor for activity. The enzyme consists of two metalloprotein components — the Fe protein and the MoFe protein — which contain different metal clusters. Electron transfer from th...
Nitrogen-fixing prokaryotes (diazotrophs) contribute substantially to nitrogen input in mangrove sediments, and their structure and nitrogen fixation rate (NFR) are significantly controlled by environmental conditions. Despite the well-known studies on diazotrophs in surficial sediments, the diversity, struct...

Yeast Saccharomyces cerevisiae is widely recognised as a versatile chassis for constructing microbial cell factories. However, producing chemicals from toxic, highly concentrated, or cell-impermeable substrates, or chemicals dependent on enzymatic reacti
11. We investigate to what extent the processes controlling net carbon fixation in the coastal ocean can keep up with the rapidly risingpCO2in the atmosphere, thus contributing to an efficient CO2transfer from the atmosphere to the global ocean. We quantify the coastal carbon budget and identify ...
Titanium (Ti) is the widely used implant material in clinic, however, failures still frequently occur due to its bioinertness and poor antibacterial property. To improve the biological and antibacterial properties of Ti implants, micro-nanostructured hydroxyapatite (HA) coating was prepared on Ti surf...
Stein and Klotz (2016) suggested five nitrogen-transformation flows (coloured arrows in Fig. 2A) which are the following: ammonification, including reduction of dinitrogen or nitrogen fixation (red), assimilatory and dissimilatory reduction of nitrite to ammonium (DNRA) (blue); nitrification (green ...

Soybean reduces 50–60% of N demand by biological nitrogen fixation [125]. Graham et al. [126] and Resende et al. [127] observed that addition of synthetic fertilizers decreased soil N stocks, while Ladha et al. [108] reported an increase in soil C pool and N stocks for long–term ...
ammonia volatilization, N2O emission and biological nitrogen fixation), resulting in decreasing N losses and improving N retention. Biochar prevents P fixation in acidic soils and increases P solubilisation as a consequence of the enhanced microbial activity as well as changing pH in soils, thus ...
