Natranaerofaba carboxydovora gen. nov., sp. nov., an extremely haloalkaliphilic CO-utilizing acetogen from a hypersaline soda lake representing a novel deep phylogenetic lineage in the class 'Natranaerobiia'. [PDF]
Environ Microbiol, 2021 Summary An anaerobic enrichment with CO from sediments of hypersaline soda lakes resulted in a methane‐forming binary culture, whereby CO was utilized by a bacterium and not the methanogenic partner. The bacterial isolate ANCO1 forms a deep‐branching phylogenetic lineage at the level of a new family within the class ‘Natranaerobiia’.

Angewandte Chemie, Volume 135, Issue 32, August 7, 2023., 2023 Carbon monoxide dehydrogenases (CODHs) are inactivated by dioxygen. High‐resolution crystallography was used to show how O2 induces a stepwise rearrangement of the Ni,Fe‐cluster in the active site, with evidence for a reversible and an irreversible phase of cluster destruction.

Insights into the Role of the D-Cluster in [NiFe]-CODH from Rhodospirillum Rubrum. [PDF]
ChemistryCarbon monoxide dehydrogenase from Rhodospirillum rubrum is a nickel enzyme that catalyses the CO2/CO interconversion thanks to a unique [Ni4Fe4S] cofactor. In addition, the enzyme has three [4Fe4S] clusters: two B‐clusters and one D‐cluster. In this study, we show that the D‐cluster plays a role not only as an electron relay but also in the ...

COx Fixation to Elementary Building Blocks: Anaerobic Syngas Fermentation vs. Chemical Catalysis
Chemie Ingenieur Technik, Volume 94, Issue 11, Page 1667-1687, November 2022., 2022 Direct usage and conversion of COx to fuels and chemicals is an important part of a carbon‐neutral circular economy. This review considers syngas fermentation and heterogeneous catalysis as two different approaches of COx fixation. Reaction paths as well as process parameters are compared, and technology‐specific advantages and disadvantages are ...

Endospores associated with deep seabed geofluid features in the eastern Gulf of Mexico
Geobiology, Volume 20, Issue 6, Page 823-836, November 2022., 2022 Abstract Recent studies have reported up to 1.9 × 1029 bacterial endospores in the upper kilometre of deep subseafloor marine sediments, however, little is understood about their origin and dispersal. In cold ocean environments, the presence of thermospores (endospores produced by thermophilic bacteria) suggests that distribution is governed by passive

Ecology and Evolution, Volume 11, Issue 9, Page 4481-4493, May 2021., 2021 This study is the first comparison of gill symbiont communities of co‐occurring invertebrates living at a single hydrothermal vent site. We observed both different compositions of gill symbionts and the presence of unshared operational taxonomic units, as well as the representative sulfur‐oxidizing γ‐proteobacterial species which is suggested to have ...
