Many Microorganisms and some macro-organisms can live under extreme conditions. For example, high and low temperature, acidic and alkaline conditions, high salt areas, high pressure, toxic compounds, high level of ionizing radiation, anoxia and absence of light, etc. Many organisms inhabit environments characterized by more than one form of stress (Polyextremophiles). Among them are those who live in hypersaline and alkaline, hot and acidic, cold/hot and high hydrostatic pressure, etc. Polyextremophiles found in desert regions have to copy with intense UV irradiation and desiccation, high as well as low temperatures, and low availability of water and nutrients. This book provides novel results of application to polyextremophiles research ranging from nanotechnology to synthetic biology to the origin of life and beyond.

Excerpt: Lichens (, sometimes ) are composite organisms consisting of a symbiotic association of a fungus (the mycobiont) with a photosynthetic partner (the photobiont or phycobiont), usually either a green alga (commonly Trebouxia) or cyanobacterium (commonly Nostoc). The morphology, physiology and biochemistry of lichens are very different from those of the isolated fungus and alga in culture. Lichens occur in some of the most extreme environments on Earth-arctic tundra, hot deserts, rocky coasts, and toxic slag heaps. However, they are also abundant as epiphytes on leaves and branches in rain forests and temperate woodland, on bare rock, including walls and gravestones, and on exposed soil surfaces (e.g., Collema) in otherwise mesic habitats. Lichens are widespread and may be long-lived; however, many are also vulnerable to environmental disturbance, and may be useful to scientists in assessing the effects of air pollution, ozone depletion, and metal contamination. Lichens have also been used in making dyes and perfumes, as well as in traditional medicines. The bodys (thallus) of most lichens is quite different from those of either the fungus or alga growing separately, and may strikingly resemble simple plants in form and growth. The fungus surrounds the algal cells, often enclosing them within complex fungal tissues unique to lichen associations. In many species the fungus penetrates the algal cell wall, forming penetration pegs or haustoria similar ...

Scheduled for its television premier in September and October of this year, the exciting series Race to Mars will be presented on the Discovery Channel in the United States and Canada. This beautiful book—the program’s companion volume—describes the dramatic chain of events that will ultimately send human beings to Mars. The story begins in ancient times when the red planet was associated with war and violence, then leads us to the American astronomer Percival Lowell. He trained his telescope on our neighboring red planet and detected surface marks that he and other observers believed were canals. Both the book and the TV account proceed to the present day, describing NASA’s series of unmanned landings, then continuing into the future, dramatizing events in the course of the projected Martian mission. The TV series will be shown in two main sections: Race to Mars summarizes the science-based fictional docudrama, a four-hour miniseries to be pres/ented on two separate evenings Mars Rising summarizes the TV documentary, to be presented as six one-hour shows This book’s magnificent illustrations include many of the high-quality photos taken by satellites and recent surface probes of Mars. Its additional illustrations include state-of-the-art visuals created especially for the TV series by author Dana Berry. Lively, readable, and scientifically accurate, Race to Mars chronicles an ongoing challenge which, if successful, will climax with one of the twenty-first century’s greatest achievements. (sidebar material) Questions Facing the Planners of the Race to Mars Will Mars astronauts be the test pilots of legend or a new breed of multi-skilled engineers? Can humans endure the extreme psychological demands of a more than two-years-long Mars mission? What unexpected mental demands will be made on the first explorers of Mars? In light of the importance of long-term team compatibility, is a mixed-gender crew the best way to go?

The available literature on freshwater fungi is limited. Over the subsequent years a considerable volume of scientific papers have appeared scattered throughout numerous journals. There is therefore no recent synthesis of the subject and this is the objective of the proposed book. Freshwater habitats are rich in fungi with some 3,000 described species, most of papers focussing on their identification, substrata they grow on and world distribution. However, these fungi play an important role in the freshwater ecosystem, and are primarily involved in the breakdown of leaf litter contributing food for detritus feeders. Our book will bring together a wide range of acclaimed mycologists to review recent developments on the biology and ecology of freshwater fungi, particularly their molecular phylogeny, biodiversity, causative diseases of freshwater amphibians, fishes and invertebrate animals, decomposition of leaf litter, stream pollution and their potential role in bioremediation.

This volume represents the first which interfaces with astronomy as the fulcrum of the sciences. It gives full expression to the human passion for the skies. Advancing human civilization has unfolded and matured this passion into the comprehensive science of astronomy. Advancing science’s quest for the first principles of existence meets the ontopoietic generative logos of life, the focal point of the New Enlightenment. It presents numerous perspectives illustrating how the interplay between human beings and the celestial realm has informed civilizational trends. Scholars and philosophers debate in physics and biology, the findings of which are opening a more inclusive, wider picture of the universe. The different models of the universal order and of life here presented, all aiming at the first principles of existence—accord with the phenomenology/ontopoiesis of life within the logos-prompted primogenital stream of becoming and action, which points to a future of progressing culture.

Project Report from the year 2018 in the subject Biology - Micro- and Molecular Biology, grade: 0, , language: English, abstract: Cellulose is one the most abundant carbon sources present on the earth. In the book, the author reported on production optimization and characterization of cellulolytic enzymes by thermophilic bacteria. Various adaptation strategies adapted by thermophilic bacteria are also discussed along with. The thermophilic bacterial strain produced cellulase in the CMC broth, pH 7 containing 0.5% peptone, 0.5% malt extract, 0.2% ammonium sulphate, 0.2% ammonium nitrate and 0.2% NaCl at 50 ̊C. Interestingly, the bacteria could not grow at 37 ̊C, confirming its thermophilic nature. Further, the cellulase was characterized after getting partially purified by ammonium sulphate precipitation method. The partially purified cellulase may be employed to hydrolyze agricultural wastes to produce bioethanol, i.e. biofuels. Thus, the present research may help solve issues of crisis of renewable energy as well as environmental pollution.

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.

With a crew of seven, the Challenger submerges three miles below the waves for a one-year mission to study the hidden world of the deep black sea. One of the team members, Ted Bell, is a former NASA scientist with his own agenda. He is much more interested in learning about the Deinococcus radiodurans bacteria that keeps sea animals alive in seven-hundred-degree, superheated water that is full of heavy metals and other toxins that flows from the “black smokers”. Ted’s ultimate goal is a mission to Mars, and if it means sacrificing the deep sea crew to advance that mission, then so be it. How is it that sea animals can live and reproduce in water that should boil them? Superheated water that is full of toxins and heavy metals, and contains almost no oxygen should be void of life on planet Earth—and yet it is teeming with it. The answer to the puzzle lies in the bacteria, and Ted knows it. Convinced that the same symbiotic relationship between the sea life and bacteria can be reproduced in humans, and then used to help humans travel to Mars one day, Ted intentionally infects a few members the crew. Just as the bacterium forces a metamorphosis in the tubeworms and other animals as the bacterium take over their host, Ted’s infected crewmates also begin their rapid transformation. And while Ted is initially thrilled with his experiments, he quickly realizes that he has lost control. As his remaining crewmates realize that they have a traitor in their midst, the fight for survival begins three miles under the waves. With two crew members transformed into “something else” and loose in the ship, the remaining crew must find a way to kill the deadly creatures that used to be their friends.
