Wood-Ljungdahl pathway encoding anaerobes facilitate low-cost primary production in hypersaline sediments at Great Salt Lake, Utah. [PDF]
FEMS Microbiol EcolAbstract Little is known of primary production in dark hypersaline ecosystems despite the prevalence of such environments on Earth today and throughout its geologic history. Here, we generated and analyzed metagenome-assembled genomes (MAGs) organized as operational taxonomic units (OTUs) from three depth intervals along a 30-cm sediment

Four families of folate-independent methionine synthases.
PLoS Genetics, 2021 Although most organisms synthesize methionine from homocysteine and methyl folates, some have "core" methionine synthases that lack folate-binding domains and use other methyl donors.

Functional Expression of the Clostridium ljungdahlii Acetyl-Coenzyme A Synthase in Clostridium acetobutylicum as Demonstrated by a Novel In Vivo CO Exchange Activity En Route to Heterologous Installation of a Functional Wood-Ljungdahl Pathway. [PDF]
Appl Environ Microbiol, 2018 ABSTRACTEngineering the Wood-Ljungdahl pathway (WLP) in the established industrial organismClostridium acetobutylicumwould allow for the conversion of carbohydrates into butanol, acetone, and other metabolites at higher yields than are currently possible, while minimizing CO2and H2release.

Ancient Metabolisms of a Thermophilic Subseafloor Bacterium
Frontiers in Microbiology, 2021 The ancient origins of metabolism may be rooted deep in oceanic crust, and these early metabolisms may have persisted in the habitable thermal anoxic aquifer where conditions remain similar to those when they first appeared.

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.

Defining Genomic and Predicted Metabolic Features of the Acetobacterium Genus
mSystems, 2020 Acetogens are anaerobic bacteria capable of fixing CO2 or CO to produce acetyl coenzyme A (acetyl-CoA) and ultimately acetate using the Wood-Ljungdahl pathway (WLP).
