Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

open access: yesEnergy Science &Engineering, Volume 14, Issue 7, Page 3388-3421, July 2026.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Temperature characteristics of methanogenic archaea and acetogenic bacteria isolated from cold environments

open access: yes, 2001
In most terrestrial ecosystems of boreal and northern climate zones degradation of organic matter with methane production occurs at low temperature. Two psychrophilic methanogenic archaea and four acetogenic bacteria were described until now.

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii

open access: yesMicrobial Biotechnology, Volume 19, Issue 6, June 2026.
Microbial electrosynthesis drives Clostridium ljungdahlii into a distinct stress‐associated physiological state, different from gas fermentation. Comparative multi‐omics and electron microscopy reveal physiological constraints that help explain the poor performance of MES.
