, 1994 The total lipids of Methanosarcina mazei accounted for 4.0% of the cell dry mass, and 90% of these were polar lipids. Nearly all of the polar fraction consisted of diether (2,3-di-O-phytanyl-sn-glycerol) and 3-hydroxydiether analogs of ...

Trace elements induce predominance among methanogenic activity in anaerobic digestion
Frontiers in Microbiology, 2016 Trace elements play an essential role in all organisms due to their functions in enzyme complexes. In anaerobic digesters, control and supplementation of trace elements lead to stable and more efficient methane production processes while trace element ...

An updated genome scale metabolic reconstruction of methanosarcina barkeri [PDF]
, 2011 Methanosarcina barkeri is a methanogen, meaning that methane is the reduced product for energy generation. M. barkeri can grow on several substrates including methanol, acetate, methyl amines and a combination of hydrogen and carbon dioxide.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.

Non-autotrophic methanogens dominate in anaerobic digesters
Scientific Reports, 2017 Anaerobic digesters are man-made habitats for fermentative and methanogenic microbes, and are characterized by extremely high concentrations of organics. However, little is known about how microbes adapt to such habitats.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Effect of Nickel Levels on Hydrogen Partial Pressure and Methane Production in Methanogens. [PDF]
PLoS ONE, 2016 Hydrogen (H2) consumption and methane (CH4) production in pure cultures of three different methanogens were investigated during cultivation with 0, 0.2 and 4.21 μM added nickel (Ni).

The FEBS Journal, EarlyView.Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...
