Several strains of Gram-negative and Gram-positive sulphate-reducing bacteria (SRB) are able to use carbon monoxide (CO) as a carbon source and electron donor for biological sulphate reduction. These strains exhibit variable resistance to CO toxicity. The most resistant SRB can grow and use CO as an electron donor at concentrations up to 100%, whereas others are already severely inhibited at CO concentrations as low as 1-2%. Here, the utilization, inhibition characteristics, and enzymology of…

Syngas as Electron Donor for Sulfate and Thiosulfate Reducing Haloalkaliphilic Microorganisms in a Gas-Lift Bioreactor

CO or syngas can be used to stimulate aggregation in haloalkaline biodesulfurization systems, and the use of H2/CO mixtures instead of pure H2 was tested to investigate the potential cost reduction of the electron donor required.

Pathways and Bioenergetics of Anaerobic Carbon Monoxide Fermentation

Three main types of fermentative CO metabolism can be distinguished: hydrogenogenesis, methanogenesis, and acetogenesis, generating hydrogen, methane and acetate, respectively, with emphasis on the potential enzymatic routes and bio-energetics involved.

Deletion of the Desulfovibrio vulgaris Carbon Monoxide Sensor Invokes Global Changes in Transcription

Global transcriptional analyses suggested that CooA and CODH are used during normal metabolism, and showed that D. vulgaris Hildenborough has an active CO dehydrogenase capable of consuming exogenous CO.

Anaerobic carboxydotrophy in sulfur-respiring haloarchaea from hypersaline lakes.

Overall, this work demonstrated for the first time the potential for anaerobic sulfur-dependent carboxydotrophy in extremely halophilic archaea.

Effect of Sulfate on Carbon Monoxide Conversion by a Thermophilic Syngas-Fermenting Culture Dominated by a Desulfofundulus Species

The carboxydotrophic potential of Desulfofundulus genus for CO conversion, both in sulfate-rich and low-sulfate environments is shown, showing the ability of D. australicus strain AB33T to use CO.

Assessment of the Carbon Monoxide Metabolism of the Hyperthermophilic Sulfate-Reducing Archaeon Archaeoglobus fulgidus VC-16 by Comparative Transcriptome Analyses

Carboxidotrophic growth seems as an intrinsic capacity of A. fulgidus with little need for novel resistance or respiratory complexes, rather than formate or H2 cycling during respiratory growth.



[Effect of carbon monoxide on the growth of sulfate-reducing bacteria and their oxidation of this substrate].

: The effect of carbon monoxide on the growth of six strains of sulfatee-reducing bacteria have been studied as well as the ability of bacterial suspensions and extracts to oxidize CO. It was shown

Microbial growth on carbon monoxide

The utilization of carbon monoxide as energy and/or carbon source by different physiological groups of bacteria is described and compared and the little information available on the nutritional and physicochemical requirements determining the sink strength is summarized.

CO metabolism of Desulfovibrio vulgaris strain Madison: physiological function in the absence or presence of exogeneous substrates

The physiological function of CO metabolism and a CO-dependent hydrogen cycle in D. vulgaris is discussed and carbon monoxide was produced and subsequently consumed during the growth of Desulfovibrio vulgaris on organic electron donors.

The ecology and biotechnology of sulphate-reducing bacteria

Sulphate-reducing bacteria (SRB) are anaerobic microorganisms that use sulphate as a terminal electron acceptor in, for example, the degradation of organic compounds. They are ubiquitous in anoxic

Carbon monoxide-dependent energy metabolism in anaerobic bacteria and archaea

Recent insights into the CO-dependent physiology of anaerobic microorganisms with a focus on methanogenic archaea are summarized and Methanosarcina acetivorans, thought to strictly rely on the process of methanogenesis, exemplifies how the beneficial redox properties of CO can be exploited in unexpected ways by anaerobia microorganisms.

The capacity of hydrogenotrophic anaerobic bacteria to compete for traces of hydrogen depends on the redox potential of the terminal electron acceptor

The effect of different electron acceptors on substrate degradation was studied in pure and mixed cultures of various hydrogenotrophic homoacetogenic, methanogenic, sulfate-reducing,

Carbon Monoxide Cycling by Desulfovibrio vulgaris Hildenborough

Alternative routes for pyruvate fermentation resulting in production of hydrogen or CO exist in D. vulgaris, and the presence of a CO dehydrogenase is indicated in the genome sequence is suggested.

Anaerobic degradation of aniline and dihydroxybenzenes by newly isolated sulfate-reducing bacteria and description of Desulfobacterium anilini

A new, rod-shaped, Gram-negative, non-sporing sulfate reducer (strain Ani1) was enriched and isolated from marine sediment with aniline as sole electron donor and carbon source. The strain degraded

Biological sulphate reduction with synthesis gas.

The objectives of this thesis are (1) to study the feasibility of using synthesis gas as electron donor and carbon source for biological sulphate reduction and (2) to develop criteria for design and

Effect of carbon monoxide, hydrogen and sulfate on thermophilic (55°C) hydrogenogenic carbon monoxide conversion in two anaerobic bioreactor sludges

Both sludges showed interesting potential for hydrogen production from CO, especially since after 30 min exposure to 95°C, the production of CH4 at 55°C was negligible, indicating that CO-rich synthesis gas can be used efficiently as an electron donor for biological sulfate reduction.
