Reference work entry


Archaea are ubiquitous in nature and thus also inhabit saline environments or have to cope with changing salt concentrations in their environment (Martin et al. 1999; Achtman and Wagner 2008). Like for bacteria, the biggest challenge is to adjust the turgor and this feature may even be of more importance since a number of archaea do not have rigid outer cell surfaces such as the peptidoglycan in the Gram-positive bacteria that contributes intrinsically to salt resistance (Kandler and König 1998; Sleytr and Beveridge 1999). Most archaea also use the “compatible solute” strategy for turgor adjustment (Galinski and Trüper 1994) and have been in the focus of research since it was hoped to find new, biotechnologically interesting compatible solutes in archaea (Sowers et al. 1990; Empadinhas et al. 2001; Pflüger et al. 2003; Saum et al. 2009a). Indeed, the nature of the compatible solutes used by bacteria and archaea is different (Roeßler and Müller 2001). Generally, the...
