Hydrogen-Oxidizing Bacteria Are Abundant in Desert Soils and Strongly Stimulated by Hydration
mSystems, 2020 How the diverse bacterial communities inhabiting desert soils maintain energy and carbon needs is much debated. Traditionally, most bacteria are thought to persist by using organic carbon synthesized by photoautotrophs following transient hydration ...

Kinetic Studies on Hydrogenase
Journal of Biological Chemistry, 1963 The kinetics of hydrogenase from Clostridium pasteurianum and from Proteus vulgaris were studied by measuring the HD and D/sub 2/ produced when the enzyme catalyzes the exchange between H/sub 2/ and 100% D/sub 2/O. The ratio of D/sub 2/ to HD production depends on the enzyme concentration because the HD produced by the exchange of H/sub 2/ can react ...

Biomass-supported catalysts on Desulfovibrio desulfuricans and Rhodobacter sphaeroides [PDF]
, 2008 A Rhodobacter sphaeroides-supported dried, ground palladium catalyst (‘‘Rs-Pd(0)’’) was compared with a Desulfovibrio desulfuricans-supported catalyst (‘‘Dd-Pd(0)’’)and with unsupported palladium metal particles made by reduction under H2 (‘‘Chem-Pd(0)’’)

Hydrogen Evolution via Oxygen Tolerant [NiFe]‐Hydrogenase Immobilized on TiO2 Nanotubes
Nano Select[FeFe]‐hydrogenase has been of great interest due to its high enzymatic activity for hydrogen evolution reactions (HERs). However, the big challenge of [FeFe]‐hydrogenase is a significant performance degradation in aerobic conditions. On the other hand, [

ADP-dependent Phosphofructokinases in Mesophilic and Thermophilic Methanogenic Archaea [PDF]
, 2001 Phosphofructokinase (PFK) is a key enzyme of the glycolytic pathway in all domains of life. Two related PFKs, ATP-dependent and PPi-dependent PFK, have been distinguished in bacteria and eucarya, as well as in some archaea.

Frontiers in Microbiology, 2019 Aerobic soil bacteria persist by scavenging molecular hydrogen (H2) from the atmosphere. This key process is the primary sink in the biogeochemical hydrogen cycle and supports the productivity of oligotrophic ecosystems.

Advanced Science, Volume 13, Issue 20, 9 April 2026.Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

Energy Conservation via Hydrogen Cycling in the Methanogenic Archaeon
mBio, 2018 Energy conservation via hydrogen cycling, which generates proton motive force by intracellular H2 production coupled to extracellular consumption, has been controversial since it was first proposed in 1981.
