The eBook is the product of a partnership between the Norwegian Eurasia Program and the China Silk Road Program. At the present, our knowledge on microbiology and biogeochemistry from Eurasian (hyper)saline and thermal ecosystems is limited. Such information is essential to the field and contributes to a comprehensive understanding of microbial metabolic pathways and functions involved in biogeochemical processes in extreme ecosystems. This eBook includes a series of recent progress in microbial diversity, ecological functions, and biogeochemistry in Eurasian (hyper)saline and thermal ecosystems with the use of next generation sequencing, omics technologies and interdisciplinary collaboration. We hope that this eBook would serve as a model for international cooperation and as a source of inspiration for more achievements in Eurasian (hyper)saline and thermal ecosystems in the future. The complete list of authors and co-authors includes 68 highly-qualified specialists from 9 countries. All chapters in the eBook were edited by authoritative experts. We would like to emphasize the great goodwill, esteem and cooperation extended to each other among the authors, reviewers and editors who contributed to the successful completion of this eBook.

This book explores various aspects of thermophilic and halophilic microbes from Eurasian ecosystems, which have proved to offer a unique reservoir of genetic diversity and biological source of extremophiles. It also covers the biotechnological uses of extremophiles, and their potential use in agricultural and industrial applications. The topics addressed include but are not limited to: diversity and microbial ecology, microbe-environment interactions, adaptation and evolution, element cycling and biotechnological applications of thermophiles and halophiles in Eurasian ecosystems. In order to review the progress made in biology and biotechnological applications of thermophiles and halophiles, the book combines review papers and results of original research from various specialists and authorities in the field. It includes several chapters describing the microbial diversity and ecology of geothermal springs distributed among the territory of various Eurasian countries, such as Armenia, Bulgaria, China, Georgia, India, Italy, Pakistan and Turkey. A dedicated chapter discusses selected aspects of thermophilic chemolithotrophic bacteria isolated from mining sites (sulfide ores); detailed descriptions of various thermophile microbes isolated from high-temperature environments and their biotechnological potential are also provided. Subsequent chapters describe the diversity and ecology of halophilic microbes harbored in saline and hypersaline lakes in Iran, Turkey and China; soil and plant microbiomes in saline arid lands of Uzbekistan; microbial diversity in Asian deserts; and the potential applications of thermophilic and halophilic microbes as exopolysaccharide (EPS) producers, focusing on the chemistry and applications of the EPS they produce. We hope that this book will prove valuable as an up-to-date overview of the current state of research on Eurasian extremophiles in general and thermophiles and halophiles in particular. Many questions remain unanswered, and we hope that it will stimulate further studies in this intriguing and promising field.

The world of halophiles is quite diverse and their representatives in three domains of life i.e. archaea, bacteria and eukarya. They are found all over the small subunit rRNA based tree of life and these micro-organisms are adapted to salt concentration up to saturation hence able to grow at >300g/l Nacl concentration. Their metabolic diversity is high as well encompassing oxygenic and anoxygenic phototrophs, aerobic heterotrophs, denitrifiers, sulphate reducers, fermenters and methanogens. The proteins of halophiles are magnificently engineered to function in a milieu containing 2-5M salt that encodes genes represent a valuable repository and resource for reconstruction and visualizing processes of habitat selection and adaptive evolution. Search for new enzymes endowed with novel activities and enhanced stability continues to be desirable purpose for important commercial production of biotechnological significance. These poly extremophiles proved excellent source of enzymes and metabolites possessing inherent ability to function in extreme conditions of high salt, alkaline pH and facilitating catalysis for industrial application in food processing, industrial bioconversion, bioremediation etc. In fact, it has just begun to realize the great potential and true extent of diversity and suitable applications if explored them judiciously. This book highlights current applications and research on halophiles to provide a timely overview. Chapters are written by expert authors from around the world and include topics of varied importance which include their role to play in enzyme production, restoration of soil fertility and plant growth , antimicrobial and biocatalytic potential, biomolecules in nanotechnology and aspects of quorum sensing. The book is divided into three sections, dealing with biodiversity, biotechnology and sustainable exploitation of halophiles. This major new work represents a valuable source of information to all those scientists interested in microorganisms in general and extremophiles in particular with respect to their innovative products and applications.

The book compiles the latest studies on microorganisms thriving in extreme conditions. Microbes have been found in extremely high and low temperatures, highly acidic to saline conditions, from deserts to the Dead sea, from hot-springs to underwater hydrothermal vents- the diversity is incredible. The various chapters highlight the microbial life and describe the mechanisms of tolerance to these harsh conditions, and show how an understanding of these phenomena can help us exploit the microbes in biotechnology. The theme of the book is highly significant since life in these environments can give vital clues about the origin and evolution of life on earth, as a lot of these conditions simulate the environment present billions of years ago. Additionally, the study of adaptation and survival of organisms in such environments can be important for finding life on other planets. This book shall be useful for students, researchers and course instructors interested in evolution, microbial adaptations and ecology in varied environments.
