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 ...

[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 ...

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.

Molecular Hydrogen and Energy Conservation in Methanogenic and Acetogenic Bacteria

1990
Molecular hydrogen is a minor constituent of our atmosphere amounting to about 0.5 ppm (Anonymus, 1976). Nevertheless, it plays an important role in the conversion of organic matter by microorganisms. Although H2 is produced in large amounts, it is rapidly consumed, and can be considered as a very convenient vehicle for transport electrons from one ...

A comparison of different methods to determine the hydrophobicity of acetogenic bacteria

Journal of Microbiological Methods, 1993
Abstract The hydrophobicity of anaerobic acetogenic bacteria was determined using variuos methods (bacterial adherence to hydrocarbons, hydrophobic interaction chromatography and the salt aggregation test) under a wide range of growth conditions.

Acetogenic bacteria: what are the in situ consequences of their diverse metabolic versatilities?

BioFactors, 1997
AbstractThe four decades of the now classic studies by Harland G. Wood and Lars G. Ljungdahl lead to the resolution of the autotrophic acetyl‐CoA 'Wood/Ljungdahl' pathway of acetogenesis. This pathway is the hallmark of acetogens, but is also used by other bacteria, including methanogens and sulfate‐reducing bacteria, for both catabolic and anabolic ...

Development of DNA Probes for the Detection and Identification of Acetogenic Bacteria

1994
Acetogenic bacteria may play an important role in anaerobic environments by supplying acetate, a major substrate for terminal carbon metabolism (Christensen, 1984; Parkes et al., 1989; Smith and Klug, 1981; Zeikus, 1977). Unfortunately, although acetogens are readily isolated and appear to occur in significant numbers in many anaerobic habitats (Braun ...
