ModE Regulates Alternative Nitrogenase Expression in the Methanogen Methanosarcina acetivorans
Molecular Microbiology, EarlyView.During nitrogen fixation, the methanogen Methanosarcina acetivorans produces the alternative vanadium‐nitrogenase and iron‐nitrogenase only when molybdenum is unavailable to support the activity of molybdenum‐nitrogenase. Our work demonstrates that the expression of the alternative nitrogenases in M.

Mechanism of Uranium Reduction and Immobilization in Desulfovibrio vulgaris Biofilms.
Environmental Science and Technology, 2015 The prevalent formation of noncrystalline U(IV) species in the subsurface and their enhanced susceptibility to reoxidation and remobilization, as compared to crystalline uraninite, raise concerns about the long-term sustainability of the bioremediation ...

Characterization of the active site and calcium binding in cytochromecnitrite reductases [PDF]
, 2011 The decahaem homodimeric cytochrome c nitrite reductase (NrfA) is expressed within the periplasm of a wide range of Gamma-, Delta- and Epsilon-proteobacteria and is responsible for the six-electron reduction of nitrite to ammonia.

Molecular Microbiology, EarlyView.The periplasmic multicopper oxidase CueO oxidizes cuprous ions (Cu+) to cupric ions (Cu2+), a well‐known process typically coupled with oxygen reduction. In this study, we report unexpected anaerobic phenotypes associated with CueO, suggesting that it may use an alternative electron acceptor in the absence of oxygen.

eFood, Volume 6, Issue 4, August 2025.Biosynthesis, characterization, and intestinal effects of nano‐selenium. ABSTRACT The bioproduction of selenium nanoparticles (SeNPs) is garnering increasing attention as an environmentally friendly method, given that many microorganisms inherently possess the ability to synthesize nano‐selenium.

Evaluating Effects of Antibiotics Across Preclinical Models of the Human Gastrointestinal Microbiota
MicrobiologyOpen, Volume 14, Issue 4, August 2025.We compared microbiota changes following antibiotic treatment in two preclinical models of the human GI microbiota, minibioreactor arrays (MBRAs) and human microbiota associated mice (HMAmice). MBRAs and HMAmice were colonized with feces from 12 or 3 healthy humans, respectively, before treatment with each of 12 or 6 antibiotics.
