...Jörg Soppa During recent years, it has become clear that many species of archaea and bacteria are polyploid and contain more than 10 copies of their chromosome. In this contribution, eight examples are discussed to highlight different aspects of polyploidy in prokaryotes. The species discussed...

... and modes of genome duplication and segregation. While clear sequence relationships between archaeal and eukaryotic replication proteins are well known, some archaea also seem to possess organizational parameters for replication and segregation that reveal further striking parallels to eukaryotes...

... are metabolically different and are adapted to extreme salinity; these microorganisms are good candidates for the bioremediation of hypersaline environments and treatment of saline effluents. This literature survey indicates that both the moderately halophilic bacteria and the extremely halophilic archaea have...

...R. Spanheimer; M. Hoffmann; S. Kögl; S. Schmidt; K. Pflüger; V. Müller Methanogenic archaea accumulate glycine betaine in response to hypersalinity, but the regulation of proteins involved, their mechanism of activation and regulation of the corresponding genes are largely unknown. Methanosarcina...

...V. Müller; T. Lemker; A. Lingl; C. Weidner; Ü. Coskun; G. Grüber Archaea are a heterogenous group of microorganisms that often thrive under harsh environmental conditions such as high temperatures, extreme pHs and high salinity. As other living cells, they use chemiosmotic mechanisms along...
