A Gas Chromatography‐Based Workflow Leads to the Detection of Hydrogenase Activity in Native Bacteria

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
A standardized gas chromatography–based workflow enables direct functional screening of hydrogenase activity in crude membrane and lysate fractions from native bacteria. Without purification or heterologous expression, hydrogen oxidation is detected across phylogenetically diverse organisms, highlighting the value of activity‐based screening for ...

Thermophiles; or, the Modern Prometheus: The Importance of Extreme Microorganisms for Understanding and Applying Extracellular Electron Transfer

Frontiers in Microbiology, 2019
Approximately four billion years ago, the first microorganisms to thrive on earth were anaerobic chemoautotrophic thermophiles, a specific group of extremophiles that survive and operate at temperatures ∼50 – 125°C and do not use molecular oxygen (O2 ...
