Metabolic Hydrogen Flows in Rumen Fermentation: Principles and Possibilities of Interventions [PDF]
Rumen fermentation affects ruminants productivity and the environmental impact of ruminant production. The release to the atmosphere of methane produced in the rumen is a loss of energy and a cause of climate change, and the profile of volatile fatty ...

Inhibiting Methanogenesis in Rumen Batch Cultures Did Not Increase the Recovery of Metabolic Hydrogen in Microbial Amino Acids [PDF]
There is an interest in controlling rumen methanogenesis as an opportunity to both decrease the emissions of greenhouse gases and improve the energy efficiency of rumen fermentation. However, the effects of inhibiting rumen methanogenesis on fermentation

Enzyme-constrained genome-scale modeling resolves growth-production trade-offs in fermentative biohydrogen production [PDF]
Hydrogen is central to sustainable energy systems, with biological production from waste offering a low-energy, environmentally compatible route. Anaerobic dark fermentation by microbes converts organic substrates into hydrogen, yet yields remain limited

Hydrogen Breath Test Dynamics Reflect Intestinal Fermentation Rather than Systemic Inflammation: A Data-Driven Diagnostic Analysis [PDF]
Background: Hydrogen breath testing is commonly used to assess intestinal fermentation and diagnose small intestinal bacterial overgrowth (SIBO). However, it remains unclear whether hydrogen production reflects systemic inflammatory or metabolic status ...

Age-related shifts of dissolved hydrogen and its impact on rumen fermentation dynamics and microbial communities in goats (Capra hircus) [PDF]
The rumen is a complex anaerobic fermentation ecosystem in which microbial communities undergo dynamic changes during host development, influencing fermentation efficiency, hydrogen utilization, and methane (CH₄) production. However, how rumen maturation
