Turning cellulose waste into electricity: hydrogen conversion by a hydrogenase electrode. [PDF]
PLoS ONE, 2013 Hydrogen-producing thermophilic cellulolytic microorganisms were isolated from cow faeces. Rates of cellulose hydrolysis and hydrogen formation were 0.2 mM L(-1) h(-1) and 1 mM L(-1) h(-1), respectively.

Recent advances in electron transfer between biofilms and metals [PDF]
, 2007 Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect

New insights into [FeFe] hydrogenase activation and maturase function. [PDF]
PLoS ONE, 2012 [FeFe] hydrogenases catalyze H(2) production using the H-cluster, an iron-sulfur cofactor that contains carbon monoxide (CO), cyanide (CN(-)), and a dithiolate bridging ligand.

Microorganisms, 2022 The cyanobacterial bidirectional [NiFe]-hydrogenase is a pentameric enzyme. Apart from the small and large hydrogenase subunits (HoxYH) it contains a diaphorase module (HoxEFU) that interacts with NAD(P)+ and ferredoxin. HoxEFU shows strong similarity to

Dual role of HupF in the biosynthesis of [NiFe] hydrogenase
BMC Microbiology, 2012 Background [NiFe] hydrogenases are enzymes that catalyze the oxidation of hydrogen into protons and electrons, to use H2 as energy source, or the production of hydrogen through proton reduction, as an escape valve for the excess of reduction equivalents ...

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]
, 2017 Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

Production of biohydrogen by recombinant expression of [NiFe]-hydrogenase 1 in
Microbial Cell Factories, 2010 Background Hydrogenases catalyze reversible reaction between hydrogen (H2) and proton. Inactivation of hydrogenase by exposure to oxygen is a critical limitation in biohydrogen production since strict anaerobic conditions are required.
