Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion [PDF]
, 2012 This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

Conversion of Kepone byMethanosarcina thermophila [PDF]
FEMS Microbiology Letters, 1996 Acetate-grown cultures of Methanosarcina thermophila converted uniformly labeled [14C]Kepone to polar and nonpolar products with 86% of the Kepone degraded within the first 10 days. The titanium(III) citrate-reduced CO dehydrogenase enzyme complex isolated from M. thermophila also catalyzed the conversion of Kepone to polar and nonpolar products with a

Augmenting Biogas Process Modeling by Resolving Intracellular Metabolic Activity [PDF]
, 2019 The process of anaerobic digestion in which waste biomass is transformed to methane by complex microbial communities has been modeled for more than 16 years by parametric gray box approaches that simplify process biology and do not resolve intracellular ...

Microbial succession during thermophilic digestion: the potential of Methanosarcina sp.
PLoS ONE, 2014 A distinct succession from a hydrolytic to a hydrogeno- and acetotrophic community was well documented by DGGE (denaturing gradient gel electrophoresis) and dHPLC (denaturing high performance liquid chromatography), and confirmed by qPCR (quantitative ...

Physiological Evidence for Isopotential Tunneling in the Electron Transport Chain of Methane-Producing Archaea [PDF]
, 2017 Many, but not all, organisms use quinones to conserve energy in their electron transport chains. Fermentative bacteria and methane-producing archaea (methanogens) do not produce quinones but have devised other ways to generate ATP. Methanophenazine (MPh)

The FEBS Journal, EarlyView.Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Dechlorination of Chloroform by Methanosarcina Strains [PDF]
Applied and Environmental Microbiology, 1990 Dehalogenation of carbon tetrachloride, chloroform, and bromoform in pure cultures of Methanosarcina sp. strain DCM and Methanosarcina mazei S6 was demonstrated. The initial dechlorination product of chloroform was methylene chloride (dichloromethane), which accumulated transiently to about ...

The FEBS Journal, EarlyView.Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

The Methanosarcina barkeri Genome: Comparative Analysis with Methanosarcina acetivorans and Methanosarcina mazei Reveals Extensive Rearrangement within Methanosarcinal Genomes [PDF]
Journal of Bacteriology, 2006 ABSTRACT We report here a comparative analysis of the genome sequence of Methanosarcina barkeri with those of Methanosarcina acetivorans and Methanosarcina mazei . The genome of M.
