Characterization and modelling of interspecies electron transfer mechanisms and microbial community dynamics of a syntrophic association [PDF]
, 2013 Syntrophic associations are central to microbial communities and thus have a fundamental role in the global carbon cycle. Despite biochemical approaches describing the physiological activity of these communities, there has been a lack of a mechanistic ...

Disentangling a metabolic cross-feeding in a halophilic archaea-bacteria consortium
Frontiers in Microbiology, 2023 Microbial syntrophy, a cooperative metabolic interaction among prokaryotes, serves a critical role in shaping communities, due to the auxotrophic nature of many microorganisms.

In Situ Metabolic Rates of Alkane-Degrading Sulphate-Reducing Bacteria in Hydrocarbon Seep Sediments Revealed by Combining CARD-FISH, NanoSIMS, and Mathematical Modelling. [PDF]
Environ MicrobiolSulphate‐reducing bacteria affiliated with clades SCA1, SCA2, and LCA2 were investigated using stable‐isotope incubations and in situ analysis at several hydrocarbon seep sites. Extrapolated rates of sulphate reduction and alkane degradation suggest that these clades play an important role at hydrocarbon seeps, contributing substantially to sulphur and

Breath-giving cooperation: critical review of origin of mitochondria hypotheses Major unanswered questions point to the importance of early ecology [PDF]
, 2017 The origin of mitochondria is a unique and hard evolutionary problem, embedded within the origin of eukaryotes. The puzzle is challenging due to the egalitarian nature of the transition where lower-level units took over energy metabolism.

Enoyl-Coenzyme A Respiration via Formate Cycling in Syntrophic Bacteria
mBio, 2022 Syntrophic bacteria play a key role in the anaerobic conversion of biological matter to methane. They convert short-chain fatty acids or alcohols to H2, formate, and acetate that serve as substrates for methanogenic archaea.

Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters. [PDF]
, 2020 Rice cultivation worldwide accounts for ∼7 to 17% of global methane emissions. Methane cycling in rice paddies is a microbial process not only involving methane producers (methanogens) and methane metabolizers (methanotrophs) but also other microbial ...
