Species-specific ribosomal RNA-FISH identifies interspecies cellular-material exchange, active-cell population dynamics and cellular localization of translation machinery in clostridial cultures and co-cultures

mSystems
The development of synthetic microbial consortia in recent years has revealed that complex interspecies interactions, notably the exchange of cytoplasmic material, exist even among organisms that originate from different ecological niches.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Reverse‐Engineered Gas‐Fermenting Acetogen Strains Recover Enhanced Phenotypes From Autotrophic Adaptive Laboratory Evolution

Microbial Biotechnology, Volume 18, Issue 8, August 2025.
We used reverse genetic engineering of the gas‐fermenting model‐acetogen Clostridium autoethanogenum to recover enhanced phenotypes from autotrophic adaptive laboratory evolution. Reverse‐engineered strains were characterised at systems level and bioinformatics suggest that the targeted genes may be involved in overlapping regulatory networks ...

Effects of Nitrate on Hydrogenogenic Carbon Monoxide Oxidation in Parageobacillus thermoglucosidasius

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Parageobacillus thermoglucosidasius hierarchically utilises nitrate respiration and hydrogenogenic carbon monoxide (CO) oxidation. Nitrate suppresses CO oxidation and promotes rapid cell growth through hydrogen‐dependent nitrate reduction. For this bacterium, CO serves as a supplemental energy source in environments lacking alternative electron ...

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 ...

Stepwise engineering of Clostridium ljungdahlii for efficient ethanol production from single-carbon gases

Green Carbon
Ethanol, a cornerstone biofuel, has been successfully produced on an industrial scale via fermentation of industrial off-gases (CO/CO2) using gas-fermenting Clostridium strains.

Methanol and Carbon Monoxide Metabolism of the Thermophile Moorella caeni

Environmental Microbiology, Volume 27, Issue 4, April 2025.
An omics approach was used to elucidate the C1 metabolism of Moorella caeni DSM 21394 T, which exhibits acetogenic metabolism on methanol and hydrogenogenic metabolism on CO. Our results suggest that respiratory Complex I serves as the primary respiratory enzyme in methanol‐grown cells.

Bioethanol Production via Syngas Fermentation

MATEC Web of Conferences, 2018
Bioconversion of C-1 carbon in syngas through microbial fermentation presents a huge potential to be further explored for ethanol production. Syngas can be obtained from the gasification of lignocellulosic biomass, by which most of carbon content of the ...

A Two-Stage Continuous Fermentation System for Conversion of Syngas into Ethanol

Energies, 2013
We have established a two-stage continuous fermentation process for production of ethanol from synthesis gas (syngas) with Clostridium ljungdahlii. The system consists of a 1-L continuously stirred tank reactor as a growth stage and a 4-L bubble column ...
