Metagenomic Insights Into the Ecology, Taxonomy and Metabolic Capabilities of ‘Candidatus Darwinibacteriales’ Ord. Nov. (Formerly MBA03), a Potential Key Player in Anaerobic Digestion

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
Metagenomic analysis of anaerobic digesters revealed a dominant, uncultured bacterial taxon—MBA03—now proposed as ‘Candidatus Darwinibacteriales’ ord. nov. This newly defined order includes potential syntrophic acetate‐oxidising bacteria (SAOB), suggesting a key role in methane production.

Gas‐Phase Integration of Trophically Distinct Microbial Cultures for Net‐Reduced CO2 and Enhanced Metabolite Production

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
A gas‐linked co‐culture system that enables spatially separated yet metabolically connected microbial interactions has been found to enhance the sustainable production of value‐added metabolites while eliminating CO2 emissions. ABSTRACT The continued increase in atmospheric CO2 concentrations has intensified global efforts to develop sustainable ...

An argument for using anaerobes as microbial cell factories to advance synthetic biology and biomanufacturing

AIChE Journal, Volume 71, Issue 6, June 2025.
Abstract Anaerobes thrive in the absence of oxygen and are an untapped reservoir of biotechnological potential. Therefore, bioprospecting efforts focused on anaerobic microbial diversity could rapidly uncover new enzymes, pathways, and chassis organisms to drive biotechnology innovation.

H2 Consumption by Various Acetogenic Bacteria Follows First‐Order Kinetics up to H2 Saturation

Biotechnology and Bioengineering, Volume 122, Issue 4, Page 804-816, April 2025.
Muñoz‐Duarte and coworkers found that H2 consumption by various acetogenic bacteria followed first‐order kinetics, i.e. the H2 consumption rate increased linearly with the dissolved H2 concentration up to H2 saturation. Biomass specific first‐order rate coefficients of eight different strains varied up to six‐fold, with the highest value for ...

From refuse to resource: exploring technological and economic dimensions of waste‐to‐energy

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 2, Page 570-592, March/April 2025.
Abstract Waste valorization offers a sustainable approach to waste management and the generation of biofuels and bioenergy, mitigating the environmental impact of fossil fuel production and use. Carbon emissions and food‐source competition associated with first‐generation biofuels production can be mitigated.

Implementation of a Clostridium luticellarii genome-scale model for upgrading syngas fermentations

Computational and Structural Biotechnology Journal
Syngas fermentation is a powerful platform for converting waste streams into sustainable carboxylic acid precursors for value-added biochemicals. Steel mills produce significant syngas, yet industrial microbial syngas valorization remains unrealized. The

A TetR-Family Protein (CAETHG_0459) Activates Transcription From a New Promoter Motif Associated With Essential Genes for Autotrophic Growth in Acetogens

Frontiers in Microbiology, 2019
Acetogens can fix carbon (CO or CO2) into acetyl-CoA via the Wood–Ljungdahl pathway (WLP) that also makes them attractive cell factories for the production of fuels and chemicals from waste feedstocks.

Evaluation of Yeast Alcohol Acetyltransferases for Ethyl Acetate Production in Clostridium ljungdahlii

Engineering in Life Sciences, Volume 25, Issue 1, January 2025.
ABSTRACT Sustainable chemical production from C1 gaseous substrates, such as syngas or CO2/H2, can be achieved through gas fermentation. In gas fermentation, acetogenic bacteria are able to utilize oxidized inorganic carbon sources as the sole carbon source and electron acceptor, while reduced inorganic species are used as the electron donor ...
