Chemistry of Hydrogen Peroxide Formation and Elimination in Mammalian Cells, and Its Role in Various Pathologies

open access: yesStresses, 2022
Hydrogen peroxide (H2O2) is a compound involved in some mammalian reactions and processes. It modulates and signals the redox metabolism of cells by acting as a messenger together with hydrogen sulfide (H2S) and the nitric oxide radical (•NO), activating

Hydrogen production from soft-drink wastewater in an upflow anaerobic packed-bed reactor [PDF]

open access: yes, 2011
The production of hydrogen from soft-drink wastewater in two upflow anaerobic packed-bed reactors was evaluated. The results show that soft-drink wastewater is a good source for hydrogen generation.

Hydrogen production by Sulfurospirillum species enables syntrophic interactions of Epsilonproteobacteria

open access: yesNature Communications, 2018
Epsilonproteobacteria, such as Sulfurospirillum, can use molecular hydrogen as an electron donor for respiration. Here, the authors show that Sulfurospirillum can, in addition, release hydrogen during fermentation, allowing metabolic interactions with ...
