Microorganisms from extreme environments have attracted the attention of many scientists and are currently one of the main focuses of research due to the fascinating mechanisms that they display in order to live under extreme conditions.One of the basic aspects of study in extremophiles is to unravel the adaptation mechanisms of these microorganisms to the severe conditions of temperature,pH or salinity of extreme habitats,and certainly the results will permit interesting developments in the future.Moreover,the extensive studies carried out during recent years have made it possible to use them as cell f- tories to produce new compounds of biotechnological importance and to develop new strategies for industrial processes. Besides thermophiles,hyperthermophiles,alkaliphiles,acidophiles or p- chrophiles,one of the most interesting groups of extremophiles is costituted by the halophilic microorganisms.These organisms require high levels of salt to grow and are common inhabitants of hypersaline environments, such as lakes,salterns or saline soils.This book is devoted to the salt-loving mic- organisms and focuses on different aspects of halophilic Archaea, Bacteria and Eukarya.

Introductory Chapter: Half a Lifetime in Soda Lakes.- 1 Trophic Ecology of Solar Salterns.- 2 Microbial Molecular and Physiological Diversity in Hypersaline Environments.- 3 Red, Extremely Halophilic, but not Archaeal: The Physiology and Ecology of Salinibacter ruber, a Bacterium Isolated from Saltern Crystallizer Ponds.- 4 The Potential Use of Signature Bases from 16S rRNA Gene Sequences to Aid the Assignment of Microbial Strains to Genera of Halobacteria.- 5 From Intraterrestrials to Extraterrestrials - Viable Haloarchaea in Ancient Salt Deposits.- 6 Fungi in the Salterns.- 7 Physiological and Molecular Responses of Bacillus subtilis to Hypertonicity: Utilization of Evolutionarily Conserved Adaptation Strategies.- 8 Genetics of Osmoadaptation by Accumulation of Compatible Solutes in the Moderate Halophile Chromohalobacter salexigens: Its Potential in Agriculture Under Osmotic Stress Conditions.- 9 Osmoregulated Solute Transport in Halophilic Bacteria.- 10 Molecular and Functional Adaptations Underlying the Exceptional Salt Tolerance of the Alga Dunaliella salina.- 11 Multienzyme Complexes in the Archaea: Predictions from Genome Sequences.- 12 Nitrate Assimilation in Halophilic Archaea.- 13 The Archaeal Cardiolipins of the Extreme Halophiles.- 14 Understanding Archaeal Protein Translocation: Haloferax volcanii as a Model System.- 15 Gas Vesicle Genes in Halophilic Archaea and Bacteria.- 16 Extremely Halophilic Archaea: Insights into Their Response to Environmental Conditions.- 17 Genome Sequences of the Head-Tail Haloviruses HF1 and HF2.- 18 Reporter Gene Systems for Halophilic Microorganisms.- 19 Industrial Enzymes: Do Halophiles and Alkaliphiles Have a Role to Play?.- 20 Extracellular Hydrolytic Enzymes Produced by Moderately Halophilic Bacteria.- 21 ModeratelyHalophilic, Exopolysaccharide-Producing Bacteria.- 22 Biotransformation of Toxic Organic and Inorganic Contaminants by Halophilic Bacteria.- Epilogue: Cum Grano Salis - Salt in the History and Life of Mankind. An Overview with Emphasis on Europe.

From the reviews:

"The origin of this book is an international meeting held on halophilic microorganisms, organized in Seville, Spain, in 2001. In 22 chapters contributed by more than 100 authors, each a specialist in his field, numerous facets of the biology of these extremophilic organisms ... are dealt with ... . this book is a must for every researcher motivated by studies on these halophilic organisms." (Klaus Hausmann, European Journal of Protistology, Vol. 41 (1), 2005)
