Halophilic Microorganisms and their Environments by Aharon Oren Pdf

"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).

Halophilic Microorganisms by Antonio Ventosa Pdf

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.

Halophiles by Dinesh K Maheshwari,Meenu Saraf Pdf

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.

Advances in Understanding the Biology of Halophilic Microorganisms by Russell H. Vreeland Pdf

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.

General and Applied Aspects of Halophilic Microorganisms by Francisco Rodriguez-Valera Pdf

During recent years the subject of extreme environments and extremophiles has become a central topic in modern Biology. The capability of some microorganisms to withstand, and often prefer, the harsh conditions found in such environments is helping to define the physicho-chemicallimits of life and in consequence its essential nature. Halophiles are one of the most representative types of extremophiles, requiring high concentrations of inorganic salts, mostly sodium chloride, to grow and survive. They inhabit hypersaline environments, the distribution and abundance of which dur ing geological eras are attested by the vast amounts of evaporite rocks present in the Earth crust and by their role in the generation of petroleum deposits. The corditions of high osmolarity and ionic strength that are concomitant with concentrated salt solutions challenge the stability of lipid bilayers and the structure of proteins forcing halophilic microbes to develop specialized molecules and physiological me;;hanisms to cope with this environmental stress. Even so, halophilism is a widespread trait in the microbial world. All the major groups of eucaryotic microbes, two groups of archaeobacteria and most phylogenetic branches of eubacteria have halophilic representatives. Therefore, the study of halophilic microorganisms is indeed a highly heterogeneous and extense topic. The present volume contains the contributions to the FEMS-NATO Advanced Research Workshop on "General and Applied Aspects of Halophilic Microorganisms" held at Alicante, Spain, September 17-22, 1989.

The Proceedings from Halophiles 2013, the International Congress on Halophilic Microorganisms by R. Thane Papke,Aharon Oren,Antonio Ventosa,Jesse Dillon Pdf

The Halophiles 2013 meeting is a multidisciplinary international congress, with a strong history of regular triennial meetings since 1978. Our mission is to bring researchers from a wide diversity of investigation interests (e.g., protein and species evolution; niche adaptation, ecology, taxonomy, genomics, metagenomics, horizontal gene transfer, gene regulation; DNA replication, repair and recombination; signal transduction; community assembly and species distribution; astrobiology; biotechnological applications; adaptation to radiation, desiccation, osmotic stress) into a single forum for the integration and synthesis of ideas and data from all three domains of life, and their viruses, yet from a single environment; salt concentrations greater than seawater. This cross-section of research informs our understanding of the microbiological world in many ways. The halophilic environment is extreme, especially above 10% NaCl, restricting life solely to microbes. The microorganisms that live there are adapted to extreme conditions, and are notable for their ability to survive high doses of radiation and desiccation. Therefore, the hypersaline environment is a model system (both the abiotic, and biologic factors) for insightful understanding regarding conditions and life in the absence of plant and animals (e.g., life on the early earth, and other solar system bodies like Mars and Europa). Lower salinity conditions (e.g., 6-10% NaCl) form luxuriant microbial mats considered modern analogues of fossilized stromatolites, which are enormous microbially produced structures fashioned during the Precambrian (and still seen today in places like Shark’s Bay, Australia). Hypersaline systems are island-like habitats spread patchily across the earth’s surface, and similar to the Galapagos Islands represent unique systems excellent for studying the evolutionary pressures that shape microbial community assembly, adaptation, and speciation. The unique adaptations to this extreme environment produce valuable proteins, enzymes and other molecules capable of remediating harsh human instigated environments, and are useful for the production of biofuels, vitamins, and retinal implants, for example. This research topic is intended to capture the breadth and depth of these topics.

Microbial Diversity by T. Satyanarayana Pdf

Microbial Diversity: Current Perspectives and Potential Applications is woven around the recent global perceptions of microbial diversity in its all embracing facets. Diversity perspectives are discussed in the context of ecosystem dynamics, taking into consideration environments that are rather unique to microorganisms. Considerable thrust is placed on the role that microorganisms play in sustainable production systems. Microbe-plant interaction arena is highlighted through the discussion of mycorrhizal partners, on which depends not only the plant community structure but also abatement of abiotic and biotic stresses. Other mutualist, rhizobia gets its due coverage whereas plant disease component carries examples from both, fungal and viral disease point of view. Considerable emphasis is placed on a discussion of the environmental issues such as the approaches that will lead to newer bioremediation technologies. No discussion of microbial diversity is complete without their implications in animal and human health. Discussed in this context are L-arginases in cancer therapy as also bioactives from cyanobacteria. Genomics and pathogenicity of two groups of viruses, viz., blue tongue and flaviviruses is highlighted whereas keratinophilic fungal forms are discussed in the context of dermatophytic infections. This volume also carries a fair number of articles on commercial microbiology.
