Environmental Microbiology, 2023 Abstract Acetogens share the capacity to convert H 2 and CO 2 into acetate for energy conservation (ATP synthesis). This reaction is attractive for applications, such as gas fermentation and microbial electrosynthesis. Different H

Diversity of Formyltetrahydrofolate Synthetases in the Guts of the Wood-Feeding Cockroach Cryptocercus punctulatus and the Omnivorous Cockroach Periplaneta americana [PDF]
, 2010 We examined the diversity of a marker gene for homoacetogens in two cockroach gut microbial communities. Formyltetrahydrofolate synthetase (FTHFS or fhs) libraries prepared from a wood-feeding cockroach, Cryptocercus punctulatus, were dominated by ...

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 ...

Formate metabolism in the acetogenic bacterium Acetobacterium woodii [PDF]
Environmental Microbiology, 2021 Summary Acetogenic bacteria are already established as biocatalysts for production of high‐value compounds from C1 substrates such as H 2 + CO 2 or CO.

Deconstructing Methanosarcina acetivorans into an acetogenic archaeon
Proceedings of the National Academy of Sciences, 2022 Significance The reductive acetyl-coenzyme A (acetyl-CoA) pathway is the only carbon fixation pathway that can also be used for energy conservation like it is known for acetogenic bacteria. In methanogenic archaea, this pathway is extended with one route toward acetyl-CoA formation for anabolism and another route toward methane ...

Current understanding of electroautotrophy and its relevance in astrobiology-related research. [PDF]
mLifeAbstract 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 ...

Frontiers in Microbiology, 2020 The formyltetrahydrofolate synthetase (FTHFS) gene is a molecular marker of choice to study the diversity of acetogenic communities. However, current analyses are limited due to lack of a high-throughput sequencing approach for FTHFS gene amplicons and a

Biotransformations of aromatic aldehydes by acetogenic bacteria [PDF]
FEMS Microbiology Letters, 1990 Vanillin was subject to O demethylation and supported growth of Clostridium formicoaceticum and Clostridium thermoaceticum. Vanillin was also stimulatory to the CO-dependent growth of Peptostreptococcus productus. The aldehyde substituent of vanillin was metabolized by routes which were dependent upon both the acetogen and a co-metabolizable substrate (

Incomplete Wood-Ljungdahl pathway facilitates one-carbon metabolism in organohalide-respiring Dehalococcoides mccartyi. [PDF]
, 2014 The acetyl-CoA "Wood-Ljungdahl" pathway couples the folate-mediated one-carbon (C1) metabolism to either CO2 reduction or acetate oxidation via acetyl-CoA.
