A two-stage strategy for methanogenesis suppression and rapid acetogenic biofilm formation in microbial electrosynthesis [PDF]

open access: yesFrontiers in Microbiology
The practical implementation of microbial electrosynthesis (MES) is currently limited by the slow microbial colonisation of the electrode and the need to suppress methanogenic activity.

Sugar-inducible promoters for manipulation of core metabolic pathways in the thermophilic acetogen Thermoanaerobacter kivui [PDF]

open access: yesApplied and Environmental Microbiology
Acetogenic 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

The microbial logic behind the prevalence of incomplete oxidation of organic compounds by acetogenic bacteria in methanogenic environments

open access: yes, 2001
Microbial degradation of organic material in methanogenic ecosystems is a multistep process in which subsequent groups use the products of the first groups of organisms in the chain as substrates.

Acetogenic Inoculum Selection for Acetate Production from Waste Biomasses via Thermal Shock Treatment

open access: yesChemical Engineering Transactions, 2022
Innovative treatment and utilization of waste biomass streams are crucial for increase environmental sustainability of human activities. Sewage sludge from the biological degradation of biomass can be valorized for the selection of biocatalysts capable ...

Biotransformations of aromatic aldehydes by acetogenic bacteria [PDF]

open access: yesFEMS 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 (

Profiling temporal dynamics of acetogenic communities in anaerobic digesters using next-generation sequencing and T-RFLP

open access: yesScientific Reports, 2021
Acetogens play a key role in anaerobic degradation of organic material and in maintaining biogas process efficiency. Profiling this community and its temporal changes can help evaluate process stability and function, especially under disturbance/stress ...

Obligate autotrophy at the thermodynamic limit of life in a new acetogenic bacterium

open access: yesFrontiers in Microbiology, 2023
One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an ...

Tolerance and Metabolic Response of Acetogenic Bacteria toward Oxygen [PDF]

open access: yesApplied and Environmental Microbiology, 2002
ABSTRACT The acetogens Sporomusa silvacetica , Moorella thermoacetica , Clostridium magnum , Acetobacterium woodii , and Thermoanaerobacter kivui (i) grew in both semisolid and liquid cultivation media ...

Energy Conservation in Acetogenic Bacteria [PDF]

open access: yesApplied and Environmental Microbiology, 2003
The anaerobic way of life comprises a great metabolic diversity and, correspondingly, diversity of energy-generating mechanisms ([52][1]). The facultative anaerobes have a respiratory system that uses preferentially oxygen, but in the absence of oxygen and presence of alternative electron ...

An ancient pathway combining carbon dioxide fixation with the generation and utilization of a sodium ion gradient for ATP synthesis [PDF]

open access: yes, 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.
