Diversity and Evolution of Methane-Related Pathways in Archaea

Annual Review of Microbiology, Год журнала: 2022, Номер 76(1), С. 727 - 755

Опубликована: Июнь 27, 2022

Methane is one of the most important greenhouse gases on Earth and holds an place in global carbon cycle. Archaea are only organisms that use methanogenesis to produce energy rely methyl-coenzyme M reductase complex (Mcr). Over last decade, new results have significantly reshaped our view diversity methane-related pathways Archaea. Many lineages synthesize or methane been identified across whole archaeal tree, leading a greatly expanded substrates mechanisms. In this review, we present state art these advances how they challenge established scenarios origin evolution methanogenesis, discuss potential trajectories may led strikingly wide range metabolisms.

Cathodic biofilms – A prerequisite for microbial electrosynthesis

Bioresource Technology, Год журнала: 2022, Номер 348, С. 126788 - 126788

Опубликована: Янв. 30, 2022

Cathodic biofilms have an important role in CO2 bio-reduction to carboxylic acids and biofuels microbial electrosynthesis (MES) cells. However, robust resilient electroactive for efficient conversion are difficult achieve. In this review, the fundamentals of cathodic biofilm formation, including energy conservation, electron transfer development catalytic biofilms, presented. addition, strategies improving such as selection electrode carrier materials, cell design operational conditions, described. The knowledge gaps individuated, possible solutions proposed achieve stable productive MES cathodes.

Methyl-Based Methanogenesis: an Ecological and Genomic Review

Microbiology and Molecular Biology Reviews, Год журнала: 2023, Номер 87(1)

Опубликована: Янв. 24, 2023

Methyl-based methanogenesis is one of three broad categories archaeal anaerobic methanogenesis, including both the methyl dismutation (methylotrophic) pathway and methyl-reducing (also known as hydrogen-dependent methylotrophic) pathway. increasingly recognized an important source methane in a variety environments.

Unraveling the phylogenomic diversity of Methanomassiliicoccales and implications for mitigating ruminant methane emissions

Genome biology, Год журнала: 2024, Номер 25(1)

Опубликована: Янв. 23, 2024

Abstract Background Methanomassiliicoccales are a recently identified order of methanogens that diverse across global environments particularly the gastrointestinal tracts animals; however, their metabolic capacities defined via limited number cultured strains. Results Here, we profile and analyze 243 genomes assembled from representatives uncultured metagenomes recovered various biomes, including different animal species. Our analyses reveal presence numerous undefined genera genetic variability in capabilities within lineages, which is essential for adaptation to ecological niches. In particular, tract demonstrate co-diversified members with hosts over evolutionary timescales likely originated natural environment. We highlight clades vitamin transporter BtuC proteins distinguish other archaeal orders provide competitive advantage efficiently handling B 12 . Furthermore, genome-centric metatranscriptomic analysis ruminants varying methane yields elevated expression select low animals suggest exchanges could enable them occupy niches possibly alter direction H 2 utilization. Conclusions comprehensive updated account divergent drawing obtained habitats. also unique involving , serve as promising targets mitigating ruminant emissions by altering flow.

MmcA is an electron conduit that facilitates both intracellular and extracellular electron transport in Methanosarcina acetivorans

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Апрель 17, 2024

Abstract Methanogens are a diverse group of Archaea that obligately couple energy conservation to the production methane. Some methanogens encode alternate pathways for conservation, like anaerobic respiration, but biochemical details this process unknown. We show multiheme c -type cytochrome called MmcA from Methanosarcina acetivorans is important intracellular electron transport during methanogenesis and can also reduce extracellular acceptors soluble Fe 3+ anthraquinone-2,6-disulfonate. Consistent with these observations, displays reversible redox features ranging −100 −450 mV versus SHE. Additionally, mutants lacking mmcA have significantly slower reduction rates. The locus prevalent in members Order Methanosarcinales part distinct clade cytochromes closely related octaheme tetrathionate reductases. Taken together, might act as an conduit potentially support variety strategies extend beyond methanogenesis.
