Interspecies Microbial Fusion and Large-Scale Exchange of Cytoplasmic Proteins and RNA in a Syntrophic Clostridium Coculture

mBio, 2020
Microbial syntrophy is universal in nature, profoundly affecting the composition and function of microbiomes. We have recently reported data suggesting direct cell-to-cell interactions leading to electron and material exchange between the two microbes in

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 ...

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.

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 ...

An ancient pathway combining carbon dioxide fixation with the generation and utilization of a sodium ion gradient for ATP synthesis [PDF]

, 2012
Synthesis of acetate from carbon dioxide and molecular hydrogen is considered to be the first carbon assimilation pathway on earth. It combines carbon dioxide fixation into acetyl-CoA with the production of ATP via an energized cell membrane.

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 ...
