TL;DR: Nitrogen is a basic element for life because it is a component of the two preeminent biological macromolecules: proteins and nucleic acids.

TL;DR: It seems that nitroreductase genes may be controlled by the MarRA and SoxRS regulatory systems that are involved in responses to several antibiotics and environmental chemical hazards and to specific oxidative stress conditions.

TL;DR: Cyanase activity was induced during growth with cyanide or cyanate, but not with ammonium or nitrate as the nitrogen source, suggesting that cyanate could be an intermediate in the cyanide degradation pathway, but alternative routes cannot be excluded.

TL;DR: Water containing cyanide was biologically detoxified with the bacterial strain Pseudomonas pseudoalcaligenes CECT5344 in a batch reactor, which constitutes an effective alternative to available physico-chemical methods for the purification of wastewater containing cyanides or cyano-metal complexes.

TL;DR: The phenotypes of defined insertion mutants constructed for each gene also indicate that periplasmic nitrate reductase from R. sphaeroides DSM 158 is a dimeric complex of a 90kDa catalytic subunit and a 15kDa cytochrome c (NAPB), which receives electrons from a membrane‐anchored tetrahaem protein, thus allowing electron flow between membrane andPeriplasm.
