Download or read book Genetics of Halophilic Microorganisms written by Rafael Montalvo-Rodriguez. This book was released on 2020-07-02. Available in PDF, EPUB and Kindle. Book excerpt: Halophilic microorganisms are found in all domains of life and thrive in hypersaline (high salt content) environments. These unusual microbes have been a subject of study for many years due to their interesting properties and physiology. Studies of the genetics of halophilic microorganisms (from gene expression and regulation to genomics) have provided understanding into the mechanisms of how life can exist at high salinity levels. Here, we highlight recent studies that advance the knowledge of biological function through examination of the genetics of halophilic microorganisms and their viruses.

Book excerpt: "This water" he told me, "runs out to the eastern region, and flows into the Arabah; and when it comes into the sea, into the sea of foul waters [i. e. , the Dead Sea], the water will become wholesome. Every living creature that swarms will be able to live wherever this stream goes; the fish will be very abundant once these waters have reached there. It will be wholesome, and everything will live wherever this stream goes. Fishermen shall stand beside it all the way from En-gedi to En-eglaim; it shall be a place for drying nets; and the fish will be of various kinds [and] most plentiful, like the fish of the Great Sea. " Ezekiel’s prophecy (Ezekiel 47: 8-10) for revival and purification of the Dead Sea waters This new book on "Halophilic Microorganisms and their Environments" is the fifth volume in the COLE series (Cellular Origin and Life in Extreme Habitats (see: http://www. wkap. nl/prod/s/COLE). In the previous books we covered aspects of enigmatic microorganisms, microbial diversity, astrobiology, and symbiosis, so this book on halophilic microbes adds a fitting link to the rest of series' books. Since ancient times hypersaline habitats have been considered extreme environments, and some were thought not to sustain life at all. Yet, every organism requires salt for its existence. Salty places have been compared to an environment of extinction (e. g. , the Dead Sea).

Book Synopsis Advances in Understanding the Biology of Halophilic Microorganisms by : Russell H. Vreeland

Download or read book Advances in Understanding the Biology of Halophilic Microorganisms written by Russell H. Vreeland. This book was released on 2012-12-14. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to be a long term career reference. The chapters present modern procedures. This is a how-to-book with a difference. These chapters: - reveal the background information about working with salt loving organisms, - are loaded with information about how experiments are conducted under high salt, - provide information about analyses that work under these conditions and those that may not, - present a wide range of details from laboratory designs to equipment used and even to simple anecdotal hints that can only come from experience. Microbiological training focuses largely on the growth, the handling and the study of the microbes associated with humans and animals. Yet the largest proportion of the Earth’s microbiota lives in saline environments such as the Oceans, saline deserts and terminal hypersaline environments. This need for salt can be intimidating for those interested in entering the field or for those interested in understanding how such research is accomplished.

Book Synopsis Halophilic Microorganisms by : Antonio Ventosa

Download or read book Halophilic Microorganisms written by Antonio Ventosa. This book was released on 2013-11-21. Available in PDF, EPUB and Kindle. Book excerpt: Various groups of microorganisms - bacteria, archaea, algae and even fungi - have adapted to a life in a hypersaline environment. Halophilic Microorganisms explores the many-fold aspects of life under these extreme conditions. Several contributions analyze the microbial communities in different hypersaline environments such as salterns, soda lakes, and the Dead Sea or salt sediments. Reviews of their biodiversity, phylogeny, and genetics are given as well as of the diverse adaptation strategies of salt-tolerant or salt-requiring microorganisms. Microorganisms that have adapted to moderate salt concentrations or to habitats with drastic fluctuations are also treated in addition to the extreme halophiles. Their physiological, biochemical and molecular mechanisms developed in response to salinity and high osmotic pressure as well as current and future biotechnological applications are presented.

Download or read book Halophiles: Genetics and Genomes written by R. Thane Papke. This book was released on 2019-04-23. Available in PDF, EPUB and Kindle. Book excerpt: Extreme halophilic environments, including salt lakes and springs, seawater evaporation facilities for the production of sea salt, and subterranean salt deposits derived from ancient oceans are distributed patchily all over the earth. The life that dominates them is microbial e.g., prokaryotes and the viruses that infect them. The best studied in these environments are the haloarchaea (family Halobacteriaceae), a diverse group of salt-loving organisms in the archaeal phylum Euryarchaeota. These remarkable organisms have an obligate requirement for salt concentrations between 10% and 35% NaCl for survival (sea water has 3.5% salt). Haloarchaea have evolved several biochemical and molecular strategies to counteract the deleterious effects of their salty environments including efficient ion pumps, UV absorbing pigments, proteins that can resistant the effects of osmotic stress and the denaturing effects of salts. The best studied extremely halophilic member of the Bacteria is Salinibacter, which is abundant in saltern crystallizer ponds worldwide. The application of modern genomic approaches to research on halophilic Archaea and Bacteria and their viruses in recent years has yielded fascinating insights into the adaptations and evolution of these unique organisms.This book highlights current genetics and genomics research to provide a timely overview. Chapters are written by expert authors from around the world and include topics such as: ecology and evolution of Haloquadratum walsbyi; microdiversity of Salinibacter ruber; horizontal gene transfer in halobacteria; comparative genomics of haloarchaeal viruses; genomics of the halophilic bacteria Natranaerobius thermophilus and Halobacillus halophilus; the haloarchaeal cell wall; cell cycle and polyploidy in haloarchaea; cell regulation by proteolytic systems and protein conjugation.This major new work represents a valuable source of information to all those scientists interested in halophilic microorganisms, extremophiles, microbial ecology and environmental microbiology.
