TLDR
This is to the authors' knowledge the first report on biological carbon monoxide formation under strictly anaerobic conditions.Abstract:
Methanobacterium thermoautotrophicum was grown in a fermenter gassed with an 80% H2/20% CO2 mixture. The effluent gas was found to contain between 30 ppm and 90 ppm carbon monoxide. Approx. 5 nmol CO were produced per min and mg cells (dry weight) by the culture. This is to our knowledge the first report on biological carbon monoxide formation under strictly anaerobic conditions.read more

Soil microorganisms as controllers of atmospheric trace gases (H2, CO, CH4, OCS, N2O, and NO).
TL;DR: It is completely unclear how important microbial diversity is for the control of trace gas flux at the ecosystem level, and different microbial communities may be part of the reason for differences in trace gas metabolism, e.g., effects of nitrogen fertilizers on CH4 uptake by soil; decrease of CH4 production with decreasing temperature.

CO2 fixation in acetogenic bacteria: Variations on a theme
TL;DR: Emphasis is placed upon the acetyl CoA pathway in acetogenic bacteria, but important advances in the study of other strict anaerobes are also considered.

Methane as fuel for anaerobic microorganisms.
Rudolf K. Thauer,Seigo Shima +1 more
TL;DR: There is evidence that anaerobic methane oxidation with sulfate proceeds at least in part via reversed methanogenesis involving the nickel enzyme methyl‐coenzyme M reductase for methane activation, which under standard conditions is an endergonic reaction, and thus inherently slow.

TL;DR: A new extremely thermophilic, anaerobic, obligately carboxydotrophic, chemolithoautotrophic freshwater bacterium, strain Z-2901, was isolated from a hot swamp of Kunashir Island, characterized by a novel type of chemotrophic metabolism.

Activity and distribution of methane-oxidizing bacteria in flooded rice soil microcosms and in rice plants (Oryza sativa)
U Bosse,Peter Frenzel +1 more
TL;DR: The activity and distribution of CH(inf4)-oxidizing bacteria (MOB) in flooded rice (Oryza sativa) soil microcosms was investigated, and the ability of these bacteria to colonize the interior of roots and culms was indicated.

Microsomal Heme Oxygenase CHARACTERIZATION OF THE ENZYME
TL;DR: The kinetics and tissue distribution of the microsomal heme oxygenase suggest that it is of major importance in the physiological degradation of hemoglobin and other hemoproteins to bile pigment.

Growth parameters ( K s , μ max , Y s ) of Methanobacterium thermoautotrophicum
TL;DR: It is indicated that methane formation and growth are less tightly coupled at high concentrations of H2 or CO2 in the medium than at low concentrations.

Carbon Monoxide Oxidation by Methanogenic Bacteria
TL;DR: Growth on CO agrees with the finding that cell-free extracts of M. thermoautotrophicum exhibited several characteristic properties found for the enzyme of Clostridium pasteurianum but differed mainly in that the clostridial enzyme did not utilize F(420) as the electron acceptor.
Journal ArticleDOI
Carbon Monoxide Oxidation by Clostridium thermoaceticum and Clostridium formicoaceticum
TL;DR: In this paper, it was shown that carbon monoxide oxidation in C. acidi-urici and C. cylindrosporum is catalyzed by a corrinoid enzyme and that in vivo the reaction is coupled with the reduction of CO(2) to acetate.
