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 ...

Repeated pulse feeding induces functional stability in anaerobic digestion [PDF]
, 2013 Anaerobic digestion is an environmental key technology in the future bio-based economy. To achieve functional stability, a minimal microbial community diversity is required. This microbial community should also have a certain “elasticity”, i.e.

SICLE: A high-throughput tool for extracting evolutionary relationships from phylogenetic trees
, 2016 We present the phylogeny analysis software SICLE (Sister Clade Extractor), an easy-to-use, high- throughput tool to describe the nearest neighbors to a node of interest in a phylogenetic tree as well as the support value for the relationship.
