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 ...

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

Functional cooperation of the glycine synthase-reductase and Wood???Ljungdahl pathways for autotrophic growth of Clostridium drakei

open access: yes, 2020
Among CO2-fixing metabolic pathways in nature, the linear Wood-Ljungdahl pathway (WLP) in phylogenetically diverse acetate-forming acetogens comprises the most energetically efficient pathway, requires the least number of reactions, and converts CO2 to ...

Effects of Bifidobacterium animalis Subsp. Lactis CP‐9 on Gut Microbiota and Immune Functions in Healthy Infants

open access: yesMicrobial Biotechnology, Volume 19, Issue 8, August 2026.
This study evaluated the 3‐month safety and tolerability of the probiotic CP‐9 in healthy infants aged 6 to 36 months. The research confirmed that, under the conditions of this study, CP‐9 can safely enrich specific beneficial bacterium in the gut without any obvious short‐term safety signal. ABSTRACT Infancy represents a critical period for growth and

Snapshots of acetyl-CoA synthesis, the final step of CO2 fixation in the Wood-Ljungdahl pathway [PDF]

open access: yes
In the ancient microbial Wood-Ljungdahl pathway, CO2 is fixed in a multi-step process ending with acetyl-CoA synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS).

Codh/Acs-Deficient Methanogens Are Prevalent in Anaerobic Digesters

open access: yesMicroorganisms, 2021
Methanogens are archaea that grow by producing methane as a catabolic end product and thrive in diverse anaerobic habitats, including soil, sediments, oil reservoirs, digestive tracts, and anaerobic digesters.

In Vivo Enzyme Catalytic Rates in Formate‐Growing Methanococcus maripaludis

open access: yesMicrobial Biotechnology, Volume 19, Issue 7, July 2026.
In vivo catalytic rates of Methanococcus maripaludis enzymes during C1 carbon source limited growth were determined from metabolic model estimated fluxes and proteomics data. They showed weak agreement with turnover numbers predicted from sequences.

A functional Wood–Ljungdahl pathway devoid of a formate dehydrogenase in the gut acetogens Blautia wexlerae, Blautia luti and beyond

open access: yes, 2022
Species of the genus Blautia are typical inhabitants of the human gut and considered as beneficial gut microbes. However, their role in the gut microbiome and their metabolic features are poorly understood. Blautia schinkii was described as an acetogenic

Homoacetogenic Conversion of Mannitol by the Thermophilic Acetogenic Bacterium Thermoanaerobacter kivui Requires External CO2

open access: yesFrontiers in Microbiology, 2020
Acetogenic microorganisms utilize organic substrates such as sugars in addition to hydrogen (H2) + carbon dioxide (CO2). Recently, we reported that the thermophilic acetogenic microorganism Thermoanaerobacter kivui is among the few acetogens that utilize
