Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Protein sequence surveys show that nickel‐ and molybdenum/copper‐containing carbon monoxide dehydrogenases (CODHs) are widespread in the ocean. Phylogenetic and genome context analyses reveal that marine CODHs are highly diverse in both evolutionary history and functional organisation.

Acetate Shock Loads Enhance CO Uptake Rates of Anaerobic Microbiomes
Microbial BiotechnologyPyrolysis of lignocellulosic biomass commonly produces syngas, a mixture of gases such as CO, CO2 and H2, as well as an aqueous solution generally rich in organic acids such as acetate.
