Can a fermentation gas mainly produced by rumen Isotrichidae ciliates be a potential source of biohydrogen and a fuel for a chemical fuel cell? [PDF]

open access: yes, 2010
Bacteria, fungi and protozoa inhabiting the rumen – the largest chamber of the ruminants’ stomach, release large quantities of hydrogen during the fermentation of carbohydrates.

The Role of Hydrogen for Sulfurimonas denitrificans’ Metabolism

open access: yesPLoS ONE, 2014
Sulfurimonas denitrificans was originally isolated from coastal marine sediments. It can grow with thiosulfate and nitrate or sulfide and oxygen. Recently sequencing of its genome revealed that it encodes periplasmic and cytoplasmic [NiFe]-hydrogenases but the role of hydrogen for its metabolism has remained unknown.
