General medium for the autotrophic cultivation of acetogens
Bioprocess and Biosystems Engineering, 2016Syngas fermentation, a microbial process in which synthesis gas serves as a substrate for acetogens, has attracted increasing interest in the last few years. For the purposeful selection of acetogens for various applications, it would be useful to characterize and compare the process performances of as many autotrophic strains as possible under ...

Sugar phosphorylation activity in ruminal acetogens
Journal of Environmental Science and Health, Part A, 2012Acetogenic bacteria Acetitomaculum ruminis, Acetobacterium woodii, and Eubacterium limosum were compared for phosphoenolpyruvate (PEP) and ATP-dependent phosphorylation of glucose and 2-deoxy-glucose. Rate of phosphorylation activity was measured in toluene-treated acetogenic cells using PEP and ATP and radiolabled glucose or 2-deoxy glucose ...

A Phylogenetic Assessment of the Acetogens
1994Our first collaborative foray into molecular systematics was a phylogenetic examination of the acetogens, beginning in 1979. Following the discovery that a physiologically defined group of microorganisms, the methanogens, corresponded to a phylogenetically coherent group (Balch et al., 1977), it was natural to ask the question whether the acetogens ...

Limitation of syntrophic coculture growth by the acetogen
Biotechnology and Bioengineering, 2015ABSTRACTThe syntrophic cooperation between hydrogen‐producing acetogens and hydrogenotrophic methanogens relies on a critical balance between both partners. A recent study, provided several indications for the dependence of the biomass‐specific growth rate of a methanogenic coculture on the acetogen.

Halophilic Acetogenic Bacteria
1994As 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.

Acetogenic Bacteria for Biotechnological Applications
2020Acetogenic 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 ...

Acetogenic bacteria are strictly anaerobic eubacteria which catalyze the formation of acetate from CO2 in their energy metabolism. The CO2 reduction to acetate can serve as an electron sink for reducing equivalents generated during oxidative degradation of carbohydrates and various other substrates. However, acetate synthesis from CO2 is also the major

A Life with Acetogens, Thermophiles, and Cellulolytic Anaerobes
Annual Review of Microbiology, 2009Frankly, I was surprised to receive an invitation to write a prefatory chapter for the Annual Review of Microbiology. I have read several such chapters written by outstanding researchers, many of whom I know and admire. I did not think I belonged to such a preeminent group.

Acetogene Aromastoffe aus Basidiomyceten
2020Aromastoffe spielen eine wichtige Rolle in der modernen Lebensmittelindustrie. Dabei bevorzugen Konsumenten nachhaltige und natürliche Produkte. Diese können biotechnologisch produziert werden. Da das Volatilom von Basidiomyceten vergleichbar zum pflanzlichen ist, besteht ein großes Potential für die Identifizierung neuer, geruchsaktiver Substanzen ...

Acetogenic and Acid-Producing Clostridia
1989Clostridia degrade a wide variety of organic compounds to mixtures of products that include acids, alcohols, CO2, and H2. The most commonly formed acids are acetate, propionate, and butyrate, but formate, lactate, succinate, and caproate are also observed as products.
