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 ...

Ultrastructure of Methanosarcina mazei
Systematic and Applied Microbiology, 1986 Summary Thin and semi-thin sections and freeze fracture replicas of unfixed, propane jet frozen cells of the methanogenic bacterium Methanosarcina mazei were examined in normal and medium-voltage (200 KV) transmission electron microscopes. A typical unit membrane surrounds the cytoplasm.

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 ...
