Type IA topoisomerases: a phylogenomic and biochemical analysis of Methanosarcina acetivorans C2A TopoIII
… these enzymes have distinct biological roles. Methanosarcinales is the only sequenced archaeal order with this distinct distribution of two TopoIIIs. And yet, there is little information currently available on archaeal TopoIII. Here we report on Methanosarcina acetivorans TopoIIIα (MacTopoIIIα) …

Organic geochemical biosignatures in alkaline Hydrothermal ecosystems
… is even stronger -- demonstrating that the Methanosarcinales in active vents are methane producers, and that they are likely carbon-limited. Archaea in other parts of the vent field at Lost City are methanotrophs. The application of lipid biomarkers helps unravel the multiple biological and …

Molecular biology approach to anaerobic digestion of marine biomass: Anaerobic digestion from marine materials. What makes a methanogen happy?
… methanogens indicate that Methanomicrobiales and Methanosarcinales-related species could dominate sediment and sludge inoculated reactors, indicating the potential for utilisation of a diverse range of substrates. Results from the functional gene clone library, suggest that hydrogenotrophic, …

Characterization of prokaryotic diversity in a chlorinated solvent-contaminated bedrock aquifer using denaturing gradient gel electrophoresis, ribosomal DNA sequencing, and real time PCR
… with the thermophilic Crenarchaeota and Methanosarcinales. The relative abundance of several microbial groups, which was determined by the use of nested Real Time-PCR (nRT-PCR), did not show any significant changes in the groundwater in relationship to depth or time. However, the relative …

Molecular, Biochemical, and Evolutionary Analysis of Single-Stranded Dna-Binding Proteins From the Mesophilic Archaeon Methanosarcina Acetivorans
… activity. This finding suggests that the Methanosarcinales might possess a ""division of labor"" among their three RPM in DNA transactions. In addition, we mimicked intramolecular and intermolecular homologous recombination process to engineer artificial RPA proteins through fusion of OB …

Mechanisms of Methanogenic Inhibition in Advanced Anaerobic Digestion
… digestion at 47°C, where the dominant order was Methanosarcinales, to high temperature thermophilic digestion at 59°C where the dominant order was Methanobacteriales. These findings support a process-driven pathway shift from aceticlastic to non-aceticlastic methanogenesis between 180 and 290 …

Geochemical characteristics and microbial diversity of CO2-rich mound springs of the Tierra Amarilla anticline, New Mexico
… Archaeal species determined that the phylotype Methanosarcinales (which is the dominate single phylotype found in Lost City hydrothermal field) is also found in the TA system. The presence of similar terrestrial communities in TA warm springs is interpreted to reflect endemic ecosystems that …
