Comparative reaction engineering analysis of different acetogenic bacteria for gas fermentation

Journal of Biotechnology, 2016
The production of chemicals by syngas fermentation is a promising alternative to heterotrophic fermentation processes. The autotrophic process performances of the so far not well studied acetogens Acetobacterium fimetarium, Acetobacterium wieringae, Blautia hydrogenotrophica, Clostridium magnum, Eubacterium aggregans, Sporomusa acidovorans, Sporomusa ...

Effect of adding acetogenic bacteria on methane production by mixed rumen microorganisms

Animal Feed Science and Technology, 1999
Six reductive acetogenic bacteria from a variety of ruminal and non-ruminal environments were investigated for their ability to prevent the accumulation of methane when added to rumen fluid incubated in vitro.

Acetogenic Bacteria for Biotechnological Applications

2020
Acetogenic bacteria are a group of strictly anaerobic bacteria that employ the Wood–Ljungdahl pathway to reduce two molecules of CO2 to acetyl-CoA, the central intermediate to various chemical compounds such as acetate, ethanol or butyrate. The capability of acetogens to utilize a wide range of substrates including industrial waste gas, methanol ...

Temperature characteristics of methanogenic archaea and acetogenic bacteria isolated from cold environments

Water Science and Technology, 2001
In most terrestrial ecosystems of boreal and northern climate zones degradation of organic matter with methane production occurs at low temperature. Two psychrophilic methanogenic archaea and four acetogenic bacteria were described until now.

Single-Carbon Chemistry of Acetogenic and Methanogenic Bacteria

Science, 1985
Methanogenic and acetogenic bacteria metabolize carbon monoxide, methanol, formate, hydrogen and carbon dioxide gases and, in the case of certain methanogens, acetate, by single-carbon (C 1 ) biochemical mechanisms. Many of these reactions occur while the C 1 compounds are linked to pteridine

Halophilic Acetogenic Bacteria

1994
As outlined in preceding chapters of this book, acetogenic bacteria have a specialized physiological potential for the conservation of energy via the reduction of CO2 to acetate. They also harbor diverse catabolic processes and are found in unusual habitats.

Energy metabolism in halophilic and alkaliphilic acetogenic bacteria

Microbiology, 2006
This review summarizes the recent data on the energy metabolism of acetogenic bacteria isolated from saline and soda lakes. It provides a general description of saline and soda lakes as microbial habitats, performs a comparative analysis of the energy metabolism of neutrophilic acetogens, considers the adaptation strategies of halophilic and ...

H2/CO2Metabolism in Acetogenic Bacteria Isolated From the Human Colon

Anaerobe, 1997
The present work reports on autotrophic metabolism in four H2/CO2-utilizing acetogenic bacteria isolated from the human colon (two Clostridium species, one Streptococcus species, and Ruminococcus hydrogenotrophicus). H2/CO2-utilization by these human acetogenic strains occurred during both exponential and stationary phases of growth.

[Sugar phosphorylation activities in acetogenic bacteria].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2004
Seven acetogenic bacteria (Acetitomaculum ruminis, Acetobacterium woodii, Eubacterium limosum as well as isolates A2, A4, A10 and H3HH) were tested for PEP- and ATP-dependent phosphorylation of glucose and 2-deoxyglucose. Although all organisms had detectable phosphorylation activity, substantial variation existed in the rates of both PEP- and ATP ...
