Sulfur reducing activity of Desulfuromonas sp. YSD S-3 bacteria under cultivation at different conditions

Біологічні студії, 2017
The sulfur reducing activity of sulfur-reducing bacteria Desulfuromonas sp. YSD S-3 for the influence of aeration, pH and temperature was studied. The highest sulfur redu­cing activity was found in culture fluid (48.4 µM H2S / (min×mg of protein), in ...

Hydrogenases and oxygen

Chemical Science, 2012
Hydrogenases represent a heterogeneous group of enzymes consisting of three evolutionary unrelated classes, i.e. [NiFe], [FeFe] and [Fe] hydrogenases. They allow the uni-cellular organisms in which they are expressed to use hydrogen as energy source or to reduce protons as a sink for excess reduction equivalents.

Sulfur Respiration in a Group of Facultatively Anaerobic Natronoarchaea Ubiquitous in Hypersaline Soda Lakes

Frontiers in Microbiology, 2018
The ubiquity of strictly anaerobic sulfur-respiring haloarchaea in hypersaline systems with circumneutral pH has shaken a traditional concept of this group as predominantly aerobic heterotrophs.

A computational study of carbene ligand stabilization of biomimetic models of the rotated Hred state of [FeFe]-hydrogenase

, 2019
Stabilization of fully rotated conformation at one of the iron center has been achieved for the reduced Fe(I)Fe(I) state in chelated cyclic alkyl amino carbene (CAAC) substituted biomimetic hydrogenase model complex. This study indicates that the spatial

Scalable bioreactor production of an O2‐protected [FeFe]‐hydrogenase enables simple aerobic handling for clean chemical synthesis

The enzyme CbA5H, a [FeFe]-hydrogenase from Clostridium beijerinckii, has previously been shown to survive exposure to oxygen, making it a promising candidate for biotechnological applications.

Predicting the Structure of Hydrogenase in Microalgae: The Case of Nannochloropsis salina

Hydrogen
The production of green hydrogen by microalgae is a promising strategy to convert energy of sun light into a carbon-free fuel. Many problems must be solved before large-scale industrial applications.

Disruption of marine green alga Platymonas subcordiformis for hydrogenase isolation under anaerobic environment

, 2008
A marine unicellular green alga, Platymonas subcordiformis, was found to evolve hydrogen via photolysis of seawater (Guan et al., 2004). To isolate and purify hydrogenase from P.

Preliminary purification of an iron hydrogenase from marine green alga Platymonas subcordiformis

, 2008
Green algae are the only eukaryotic organisms for which hydrogenase activity has been well documented (Ueno et al., 1999). In this study, hydrogenase from a marine green alga Platymonas subcordiformis (Guan et al., 2004), was purified through three steps
