Intramolecular electron transfer in Pseudomonas aeruginosa cd1 nitrite reductase: thermodynamics and kinetics

open access: yes, 2009
: The cd(1) nitrite reductases, which catalyze the reduction of nitrite to nitric oxide, are homodimers of 60 kDa subunits, each containing one heme-c and one heme-d(1).

Earthworms With Low Dose n‐MoS2 Improve Soybean Yield and Quality by Reconfiguring Rhizosphere Chemistry and Strengthening Nitrogen Fixation

open access: yesPhysiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Nano‐enabled fertilizers can enhance biological nitrogen fixation (BNF) and yield in legumes; yet, their interactions with earthworms remain poorly understood. Herein, we performed a 120‐day greenhouse experiment applying low‐dose n‐MoS2 at 10 mg kg−1 with earthworms to evaluate interactive effects on soybean yield and underlying mechanisms ...

The catalytic mechanism of Pseudomonas aeruginosa cd1 nitrite reductase

open access: yes, 2011
The cd1 NiRs (nitrite reductases) are enzymes catalysing the reduction of nitrite to NO (nitric oxide) in the bacterial energy conversion denitrification process.

The regulation of glutamate dehydrogenase, nitrite reductase, and nitrate reductase in excised pea roots by nitrite

open access: yesBiologia Plantarum, 1973
Both nitrite reductase and nitrate reductase were induced by nitrite, but there were differences in the time course of induction and in the response to different NO2 - concentrations between these enzymes. NH4 + depressed the induction of nitrite reductase. NADH2 dependent glutamate dehydrogenase activity was enhanced by those NO2-concentrations in the

Denitrification, activity of bacterial flocs, and growth of a filamentous bacterium in relation with the bulking of activated sludge

open access: yes, 1978
Activated sludge with poor settling characteristics is caught under the term "bulking" sludge. Various types of bulking activated sludge can be distinguished.1) Sludge containing an abundance of filamentous microorganisms.2) Sludge, characterized by ...
