The root zone of graminoids: A niche for H2-consuming acetogens in a minerotrophic peatland [PDF]
Frontiers in Microbiology, 2022 The importance of acetogens for H2 turnover and overall anaerobic degradation in peatlands remains elusive. In the well-studied minerotrophic peatland fen Schlöppnerbrunnen, H2-consuming acetogens are conceptualized to be largely outcompeted by iron ...

Old Acetogens, New Light [PDF]
Annals of the New York Academy of Sciences, 2008 Acetogens utilize the acetyl‐CoA Wood‐Ljungdahl pathway as a terminal electron‐accepting, energy‐conserving, CO2‐fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only harbor a novel CO2‐fixing pathway, but are also ecologically important, and (2) overshadowed the ...

Sugar-inducible promoters for manipulation of core metabolic pathways in the thermophilic acetogen Thermoanaerobacter kivui [PDF]
Applied and Environmental MicrobiologyAcetogenic bacteria form an essential part of the global carbon cycle and show promise for green chemicals production thanks to their energy-efficient carbon fixation via the Wood-Ljungdahl pathway. Energy conservation in acetogens is dependent on one of
