Carbonic anhydrase in Acetobacterium woodii and other acetogenic bacteria [PDF]

Journal of Bacteriology, 1997
Acetobacterium woodii, Acetohalobium arabaticum, Clostridium formicoaceticum, and Sporomusa silvacetica were found to contain carbonic anhydrase (CA). Minimal to no CA activity was detected in Moorella thermoautotrophica, Moorella thermoacetica subsp. "pratumsolum," Sporomusa termitida, and Thermoanaerobacter kivui. Of the acetogens tested, A.

Genetic Evidence Reveals the Indispensable Role of the rseC Gene for Autotrophy and the Importance of a Functional Electron Balance for Nitrate Reduction in Clostridium ljungdahlii

Frontiers in Microbiology, 2022
For Clostridium ljungdahlii, the RNF complex plays a key role for energy conversion from gaseous substrates such as hydrogen and carbon dioxide. In a previous study, a disruption of RNF-complex genes led to the loss of autotrophy, while heterotrophy was ...

Evaluation of Media Components and Process Parameters in a Sensitive and Robust Fed-Batch Syngas Fermentation System with Clostridium ljungdahlii

Fermentation, 2020
The fermentation of synthesis gas, or syngas, by acetogenic bacteria can help in transitioning from a fossil-fuel-based to a renewable bioeconomy. The main fermentation products of Clostridium ljungdahlii, one of such microorganisms, are acetate and ...

Energy Conservation in the Acetogenic Bacterium Clostridium aceticum

Microorganisms, 2021
In times of global warming caused by the extensive use of fossil fuels, the need to capture gaseous carbon compounds is growing bigger. Several groups of microorganisms can fix the greenhouse gas CO2.

Non-Growth-Associated Demethylation of Dimethylsulfoniopropionate by (Homo)acetogenic Bacteria [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT The demethylation of the algal osmolyte dimethylsulfoniopropionate (DMSP) to methylthiopropionate (MTPA) by (homo)acetogenic bacteria was studied. Five Eubacterium limosum strains (including the type strain), Sporomusa ovata DSM 2662 T ...

Recent Trends in Biogenic Gas, Waste and Wastewater Fermentation

Fermentation, 2022
In recent years, the optimization of bioprocesses for the removal of pollutants from industrial biogenic gas emissions, waste and wastewater has been the focus of intensive research. Recently developed technologies not only aim to remove such pollutants,

Insights into the genome structure of four acetogenic bacteria with specific reference to the Wood–Ljungdahl pathway

MicrobiologyOpen, 2019
Acetogenic bacteria are obligate anaerobes with the ability of converting carbon dioxide and other one‐carbon substrates into acetate through the Wood–Ljungdahl (WL) pathway.

Overcoming Energetic Barriers in Acetogenic C1 Conversion

Frontiers in Bioengineering and Biotechnology, 2020
Currently one of the biggest challenges for society is to combat global warming. A solution to this global threat is the implementation of a CO2-based bioeconomy and a H2-based bioenergy economy.

Revealing formate production from carbon monoxide in wild type and mutants of Rnf‐ and Ech‐containing acetogens, Acetobacterium woodii and Thermoanaerobacter kivui

Microbial Biotechnology, 2020
Summary Acetogenic bacteria have gained much attraction in recent years as they can produce different biofuels and biochemicals from H2 plus CO2 or even CO alone, therefore opening a promising alternative route for the production of biofuels from ...

Metabolic changes of the acetogen Clostridium sp. AWRP through adaptation to acetate challenge

Frontiers in Microbiology, 2022
In this study, we report the phenotypic changes that occurred in the acetogenic bacterium Clostridium sp. AWRP as a result of an adaptive laboratory evolution (ALE) under the acetate challenge. Acetate-adapted strain 46 T-a displayed acetate tolerance to
