Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

open access: yesJournal 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 ...

A moderately thermophilic origin of a novel family of marine group II euryarchaeota from deep ocean

open access: yesiScience, 2023
Summary: Marine group II (MGII) is the most abundant planktonic heterotrophic archaea in the ocean. The evolutionary history of MGII archaea is elusive. In this study, 13 new MGII metagenome-assembled genomes were recovered from surface to the hadal zone

Soil Microbiomes Across Depth and Ecosystems in Dubai, UAE: Potential Environmental Signatures for Forensic Geolocation

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Soil microbiomes from diverse Dubai environments were profiled using a high‐throughput sequencing approach. Distinct microbial signatures were identified across sites, enabling comparative taxonomic and diversity analyses. These microbial fingerprints demonstrate potential for forensic geolocation, supporting the use of soil microbiome profiling as a ...

Effect of hay supplementation timing on rumen microbiota in suckling calves

open access: yesMicrobiologyOpen, 2018
An animal feeding trial was conducted on 18 seven‐day‐old Holstein dairy bull calves weighing 42 ± 3 kg each. Calves were randomly assigned into three groups (n = 6 each). The dietary treatments were as follows: (1) milk and starter for the control group

Archaeal tRNA-Splicing Endonuclease as an Effector for RNA Recombination and Novel Trans-Splicing Pathways in Eukaryotes

open access: yesJournal of Fungi, 2021
We have characterized a homodimeric tRNA endonuclease from the euryarchaeota Ferroplasma acidarmanus (FERAC), a facultative anaerobe which can grow at temperatures ranging from 35 to 42 °C. This enzyme, contrary to the eukaryal tRNA endonucleases and the

Biomethane Energy Production Using Orange Hydrogen Coupled With CO2 Sequestration and Utilization

open access: yesCarbon Neutralization, Volume 5, Issue 4, July 2026.
In subsurface hydrocarbon‐simulated environments, injected CO2 follows dual transformation routes: geochemical mineralization into stable carbonates (CCS) and microbially mediated conversion into CH4 energy through anaerobic metabolic processes. ABSTRACT The escalating concerns of global warming have intensified the global demand for clean energy ...

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).
