A phylogenetic approach to the early evolution of autotrophy: the case of the reverse TCA and the reductive acetyl-CoA pathways [PDF]

, 2014
In recent decades, a number of hypotheses on the autotrophic origin of life have been presented. These proposals invoke the emergence of reaction networks leading from CO or CO2 to the organic molecules required for life.

Life in Hot Carbon Monoxide: The Complete Genome Sequence of Carboxydothermus hydrogenoformans Z-2901 [PDF]

, 2005
We report here the sequencing and analysis of the genome of the thermophilic bacterium Carboxydothermus hydrogenoformans Z-2901. This species is a model for studies of hydrogenogens, which are diverse bacteria and archaea that grow anaerobically ...

Direct carbon monoxide fixation via the bacterial and archaeal Wood–Ljungdahl pathways

Abstract The Wood–Ljungdahl (WL) pathway, which is widely distributed in both archaea and bacteria, is an ancient carbon fixation pathway from CO 2 . CO 2 fixation proceeds via two branches of pathway: progressive reduction to the methyl group in ...

Clostridium autoethanogenum alters cofactor synthesis, redox metabolism, and lysine-acetylation in response to elevated H2:CO feedstock ratios for enhancing carbon capture efficiency

Biotechnology for Biofuels and Bioproducts
Background Clostridium autoethanogenum is an acetogenic bacterium that autotrophically converts carbon monoxide (CO) and carbon dioxide (CO2) gases into bioproducts and fuels via the Wood–Ljungdahl pathway (WLP).

Uneven distribution of cobamide biosynthesis and dependence in bacteria predicted by comparative genomics. [PDF]

, 2019
The vitamin B12 family of cofactors known as cobamides are essential for a variety of microbial metabolisms. We used comparative genomics of 11,000 bacterial species to analyze the extent and distribution of cobamide production and use across bacteria ...

Cultivation of novel Atribacterota from oil well provides new insight into their diversity, ecology, and evolution in anoxic, carbon-rich environments

Microbiome
Background The Atribacterota are widely distributed in the subsurface biosphere. Recently, the first Atribacterota isolate was described and the number of Atribacterota genome sequences retrieved from environmental samples has increased significantly ...

Asgard archaea modulate potential methanogenesis substrates in wetland soil

Nature Communications
The roles of Asgard archaea in eukaryogenesis and marine biogeochemical cycles are well studied, yet their contributions in soil ecosystems remain unknown. Of particular interest are Asgard archaeal contributions to methane cycling in wetland soils.

Microbial Community and Metabolic Pathways in Anaerobic Digestion of Organic Solid Wastes: Progress, Challenges and Prospects

Fermentation
Anaerobic digestion (AD) is a sustainable and widely adopted technology for the treatment of organic solid wastes (OSWs). However, AD efficiency varies significantly across different substrates, primarily due to differences in the microbial community and

Snapshots of acetyl-CoA synthesis, the final step of CO₂fixation in the Wood-Ljungdahl pathway

ABSTRACTIn the ancient microbial Wood-Ljungdahl pathway, CO2is fixed in a multi-step process ending with acetyl-CoA synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS). Here, we present catalytic snapshots of the CODH/ACS from the gas-converting acetogenClostridium autoethanogenum, characterizing the ...
