The conversion of biomass to CH4 (biomethanation) involves an anaerobic microbial food
chain composed of at least three metabolic groups of which the first two decompose the …

The timing of early cellular evolution, from the divergence of Archaea and Bacteria to the
origin of eukaryotes, is poorly constrained. The ATP synthase complex is thought to have …

Genetic techniques for the Archaea have undergone a rapid expansion in complexity,
resulting in increased exploration of the role of Archaea in the environment and detailed …

Methanosarcina acetivorans strain C2A is a marine methanogenic archaeon notable for its
substrate utilization, genetic tractability, and novel energy conservation mechanisms. To …

An analysis of the distribution of the Na+-translocating ATPases/ATP synthases among
microbial genomes identified an atypical form of the F1Fo-type ATPase that is present in the …

This section provides an overview of the genetic systems developed in the Archaea. Genetic
manipulation is possible in many members of the halophiles, methanogens, Sulfolobus, and …

Background Acetate is the major source of methane in nature. The majority of investigations
have focused on acetotrophic methanogens for which energy-conserving electron transport …

Methanogenic archaea belonging to the Order Methanosarcinales conserve energy using
an electron transport chain (ETC). In the genetically tractable strain Methanosarcina …

Abstract Background The archaeon, Methanosarcina acetivorans strain C2A forms methane,
a potent greenhouse gas, from a variety of one-carbon substrates and acetate. Whereas the …

The genome-wide transcriptional responses of the strictly aerobic α-proteobacterium
Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 …
