Molecular diversity of rumen methanogens in sheep in Queensland, Australia was investigated using 16S rRNA gene libraries prepared from pooled rumen contents from nine merino sheep. A total of 78 clon...
Pyruvate kinases (PK, EC 2.7.1.40) from three hyperthermophilic archaea (Archaeoglobus fulgidus strain 7324, Aeropyrum pernix, and Pyrobaculum aerophilum) and from the hyperthermophilic bacterium Ther...
In the late 1970s, on the basis of rRNA phylogeny, Archaea (archaebacteria) was identified as a distinct domain of life besides Bacteria (eubacteria) and Eucarya. Though forming a separate domain, Arc...
The Archaea, designated since 1979 as a separate Super-Kingdom (the highest taxonomic order), are a highly novel group of microorganisms which look much like bacteria but have many molecular and genet...
