Metagenomic and physicochemical profiling reveal microbial functions in pit mud for Jiang-Nong Jianxiang Baijiu fermentation [PDF]

BMC Microbiology
Background The unique flavour and quality of Baijiu, a treasure of traditional Chinese culture, has attracted increasing attention. The pit mud is a key component for forming the unique flavour styles of different Baijiu brands.

Insights into pyrrolysine function from structures of a trimethylamine methyltransferase and its corrinoid protein complex

Communications Biology, 2023
Structures of Methanosarcina barkeri trimethylamine methyltransferase (MttB) with its substrates reveal the role of pyrrolysine in methyl group transfer from trimethylamine to the corrinoid cofactor in MttC.

Acetate assimilation pathway of Methanosarcina barkeri [PDF]

Journal of Bacteriology, 1979
The pathway of acetate assimilation in Methanosarcina barkeri was determined from analysis of the position of label in alanine, aspartate, and glutamate formed in cells grown in the presence of [14C]acetate and by measurement of enzyme activities in cell extracts.

Necessity of electrically conductive pili for methanogenesis with magnetite stimulation [PDF]

PeerJ, 2018
Background Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments.

Nitrogenase in the archaebacterium Methanosarcina barkeri 227 [PDF]

Journal of Bacteriology, 1990
The discovery of nitrogen fixation in the archaebacterium Methanosarcina barkeri 227 raises questions concerning the similarity of archaebacterial nitrogenases to Mo and alternative nitrogenases in eubacteria. A scheme for achieving a 20- to 40-fold partial purification of nitrogenase components from strain 227 was developed by using protamine sulfate ...

Sustained Biotic-Abiotic Hybrids Methanogenesis Enabled Using Metal-Free Black Phosphorus/Carbon Nitride

Frontiers in Microbiology, 2022
Biotic-abiotic hybrid systems (BAHs) constructed by integrating biological methanogens with photocatalysts offer novel approaches for the effective solar-driven conversion of CO2 to CH4, providing significant inspiration for achieving carbon neutrality ...

Different outer membrane c‐type cytochromes are involved in direct interspecies electron transfer to Geobacter or Methanosarcina species

mLife, 2022
Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor.

Putative Extracellular Electron Transfer in Methanogenic Archaea

Frontiers in Microbiology, 2021
It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.
