Solar-driven carbon dioxide fixation using photosynthetic semiconductor bio-hybrids. [PDF]
, 2019 Solar-driven conversion of carbon dioxide to value-added carbon products is an ambitious objective of ongoing research efforts. However, high overpotential, low selectivity and poor CO2 mass transfer plague purely inorganic electrocatalysts.

Remnants of an ancient metabolism without phosphate [PDF]
, 2017 Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.

Plant Biotechnology Journal, EarlyView.ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

Frontiers in Microbiology, 2018 Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

The Redox Couple of the Cytochrome \u3cem\u3ec\u3c/em\u3e Cyanide Complex: The Contribution of Heme Iron Ligation to the Structural Stability, Chemical Reactivity, and Physiological Behavior of Horse Cytochrome \u3cem\u3ec\u3c/em\u3e [PDF]
, 2006 Contrary to most heme proteins, ferrous cytochrome c does not bind ligands such as cyanide and CO. In order to quantify this observation, the redox potential of the ferric/ferrous cytochrome c–cyanide redox couple was determined for the first time by ...

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.Dietary approaches that decrease ruminal pH may be combined with anti‐methanogenic feed additives that prevent methane formation and consequently increase the dissolved hydrogen concentration. To evaluate the effect of pH and the effect of dissolved hydrogen concentration, two forages (forage rape and ryegrass) were incubated in vitro at two forage ...

Electron transport in acetate-grown
BMC Microbiology, 2011 Background Acetate is the major source of methane in nature. The majority of investigations have focused on acetotrophic methanogens for which energy-conserving electron transport is dependent on the production and consumption of H2 as an intermediate ...

How many metals does it take to fix N2? A mechanistic overview of biological nitrogen fixation [PDF]
, 2006 During the process of biological nitrogen fixation, the enzyme nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia. Nitrogenase consists of two component metalloproteins, the iron (Fe) protein and the molybdenum-iron (MoFe) protein;

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Electron bifurcation mechanism and homoacetogenesis explain products yields in mixed culture anaerobic fermentations [PDF]
, 2017 Anaerobic fermentation of organic wastes using microbial mixed cultures is a promising avenue to treat residues and obtain added-value products. However, the process has some important limitations that prevented so far any industrial application.
