“…Acetobacterium woodii was isolated from a former ocean inlet that was closed off but had characteristics similar to the sea (Drake et al ., 2008; Kremp et al ., 2018). Furthermore, Schuppert and Schink (1990) isolated an acetogen from the marine Rio Marin in Venice, Italy (Schuppert and Schink, 1990). However, this strain was never deposited in a culture collection.…”

Methanol is an ubiquitous compound that plays a role in microbial processes as a carbon and energy source, intermediate in metabolic processes or as end product in fermentation. In anoxic environments, methanol can act as the sole carbon and energy source for several guilds of microorganisms: sulfatereducing microorganisms, nitrate-reducing microorganisms, acetogens and methanogens. In marine sediments, these guilds compete for methanol as their common substrate, employing different biochemical pathways. In this review, we will give an overview of current knowledge of the various ways in which methanol reaches marine sediments, the ecology of microorganisms capable of utilizing methanol and their metabolism. Furthermore, through a metagenomic analysis, we shed light on the unknown diversity of methanol utilizers in marine sediments which is yet to be explored.

“…2,3-Butanediol is another product that can be derived from pyruvate. Acetolactate synthase (ALS), acetolactate decarboxylase (ALDC), and 2,3-butanediol dehydrogenase (2,3-BDH) are participating in the transformation from pyruvate to acetolactate, acetoin, and 2,3-butanediol, respectively. , Methanogen, a methane-producing bacterium, can grow on gaseous chemicals, including hydrogen ( Methanobacterium bryanti , Methanobacterium thermoautotrophicum , Methanobrevibacter arboriphilus A2 , Methanococcus maripaludis , etc.) and carbon monoxide ( Methanobacterium thermoautotrophicum , Methanosarcina barkeri , etc.).…”

“…and not from formate dehydrogenase. Several bacteria, including acetobacterium woodii , − acetobacterium KoMac1 , acetobacteriurn malicum MuME1 , and sporomusa malonica WoGl2 , are able to use formate as feedstock and generating acetate. Similar to acetogens, methanogenic growth on formate is viable as well.…”

Catalytic Hybrid Electrocatalytic/Biocatalytic Cascades for Carbon Dioxide Reduction and Valorization

Carbon dioxide, as a greenhouse gas, has a critical impact on global climate change. Hence, reducing its emissions and/or transforming it into value-added chemicals is of paramount importance to society. Such a goal can be achieved through the development of electrochemical catalytic processes, which showed initial successes in synthesizing CO and cosynthesis of H 2 (syngas) from CO 2 . However, to further advance the technology toward more complex hydrocarbons (possibly fuels) and more complex organic molecules to be used in industrial chemical synthesis of rubber/resins and plastics or even fine chemical synthesis of pharmaceuticals, catalytic structures have to be designed beyond simple materials. One approach consists of executing the required steps linking CO and small alcohols and the desired products through chemical reactions catalyzed by enzymes or microorganisms, hence combining them with the electrocatalysts used for the initial steps of the CO 2 reduction. Here, we discuss the electrocatalysts, enzymes, and bacteria to be used for those cascade reactions. Inorganic catalysts can be directly utilized for initial steps of CO 2 reduction resulting in formate, carbon monoxide, and methanol, which then can be further reduced by employing enzymatic catalysts such as carbonic anhydrase and formate dehydrogenase, formaldehyde dehydrogenase, and alcohol dehydrogenase. Formate, carbon monoxide, and methanol can also be converted to acetyl-CoA and pyruvate, which are critical intermediates in the production of various chemicals of critical importance. Furthermore, if a chemolithoautotrophic bacteria is employed, the former can be used as a feedstock for biomass. A special emphasis is here given to the compatibility of the different classes of electrocatalysts used in the cascade: heterogeneous electrocatalysts (metals and metal oxides/carbides/nitrites, atomically dispersed transition metal−nitrogen-carbon, etc.), enzymatic catalysts (individually purified enzymes or multienzymatic complexes), bacterial cells (pure or mixed cultures of different classes, planktonic, or biofilm-forming), and their integration in singular bed reactors or multireactors units required for the formation of the products of interest. The electrocatalysts and related cascade reaction pathways are summarized in a descriptive "connectivity map" identifying the most important reaction pathways.

“…Tree construction followed that described in the caption for microorganisms might be implicated in the removal of PEG. A number of Acetobacterium species, including A. malicum, can grow at the expense of glycol ethers which are metabolized to acetate (Schuppert and Schink 1990;Tanaka and Pfennig 1988). Anaerobic fermentation of polymeric PEG compounds has been described for an Acetobacterium sp.…”

Molecular characterization of mesophilic and thermophilic sulfate reducing microbial communities in expanded granular sludge bed (EGSB) reactors

The microbial communities established in mesophilic and thermophilic expanded granular sludge bed reactors operated with sulfate as the electron acceptor were analyzed using 16S rRNA targeted molecular methods, including denaturing gradient gel electrophoresis, cloning, and phylogenetic analysis. Bacterial and archaeal communities were examined over 450 days of operation treating ethanol (thermophilic reactor) or ethanol and later a simulated semiconductor manufacturing wastewater containing citrate, isopropanol, and polyethylene glycol 300 (mesophilic reactor), with and without
