Acetogenesis in the energy-starved deep biosphere – a paradox?

Frontiers in Microbiology, 2012
Under anoxic conditions in sediments, acetogens are often thought to be outcompeted by microorganisms performing energetically more favorable metabolic pathways, such as sulfate reduction or methanogenesis. Recent evidence from deep subseafloor sediments

The Complete Genome Sequence of Clostridium aceticum: a Missing Link between Rnf- and Cytochrome-Containing Autotrophic Acetogens

, 2015
Clostridium aceticum was the first isolated autotrophic acetogen, converting CO2 plus H2 or syngas to acetate. Its genome has now been completely sequenced and consists of a 4.2-Mbp chromosome and a small circular plasmid of 5.7 kbp.

Competition and coexistence of sulfate-reducing bacteria, acetogens and methanogens in a lab-scale anaerobic bioreactor as affected by changing substrate to sulfate ratio [PDF]

, 2008
The microbial population structure and function of natural anaerobic communities maintained in lab-scale continuously stirred tank reactors at different lactate to sulfate ratios and in the absence of sulfate were analyzed using an integrated approach of

Acetogens beyond gas fermentation : enhancing bioconversion of lignocellulosic biomass

As the demand for sustainable and cost-effective bioprocesses intensifies, acetogenic bacteria have gained renewed attention for their unique metabolic capabilities. Traditionally recognised for their role in gas fermentation, these anaerobes fix CO2 and

Regulation of endogenous acyl homoserine lactones by microbial density to enhance syntrophism of acetogens and methanogens in anaerobic digestion

, 2019
To understand the syntrophic mechanism of acetogens and methanogens in anaerobic digestion (AD), functional floras of syntrophic propionate-oxidizing bacteria (SPOB), syntrophic butyrate-oxidizing bacteria (SBOB), aceticlastic methanogens (AM) and ...

Acetogen Communities in the Gut of Herbivores and Their Potential Role in Syngas Fermentation

Fermentation, 2018
To better understand the effects of host selection on gut acetogens and their potential role in syngas fermentation, the composition and hydrogenotrophic features of acetogen populations in cow and sheep rumens, rabbit ceca, and horse feces were studied.

Metabolic versatility of acetogens in syngas fermentation: responding to varying CO availability [PDF]

Syngas fermentation using acetogenic bacteria offers a promising route for sustainable chemical production. However, gasliquid mass transfer limitations and efficient co-utilization of CO and H2 pose significant challenges.

Pathway engineering and synthetic biology using acetogens

, 2012
Acetogenic anaerobic bacteria are defined as organisms employing the Wood–Ljungdahl pathway to synthesize acetyl-CoA from CO2 or CO. Their autotrophic mode of metabolism offers the biotechnological chance to combine use of abundantly available substrates
