Book Description: Modern methods and approaches, such as the analysis of molecular sequences to infer evolutionary relationships among organisms, have provided vast new sets of data to further our understanding ofliving organisms, but there remain enigmas in the biological world that will keep scientists working and thinking for decades. Microorganisms by virtue of their small size and almost unbounded diversity provide ample examples of intriguing mysteries that are being challenged with all of the techniques the modern scientific arsenal can provide. One whole arena of this battle to resolve puzzling mysteries about various microorganisms is the almost unbelievable ability of many micro-organisms to live in extreme environments. Whether the challenge is extreme heat, cold, pressure, hyper salinity, alkalinity or acidity, some micro-organisms live now where no life might seem possible. This fascinating state of affairs is the context for this present volume edited by Joseph Seckbach. This Volume is a compilation of many of the especially interesting questions and biological challenges that arise in the consideration of microorganisms in general and the extremophiles in particular.

Book Description: Algae and Cyanobacteria in Extreme Environments is a unique collection of essays, contributed by leading scientists from around the world, devoted to algae – and some related microbes – observed in unexpected harsh habitats, which it seems are an oasis or Garden of Eden for these organisms. This timely book on Extremophilic algae, including its especially impressive micrographs, may provide clues about the edges of life on Earth and possibly elsewhere in the universe. Defining locations from the anthropomorphic point of view, the environments explored ranges from severe and distant to “normal” places. The algae discussed, microbial oxygenic phototrophs, are classified into various categories according to their habitats. They thrive in various temperature ranges, at the limits of pH values, in salt solutions, under UV radiation, dryness, heavy metals, anaerobic niches, under various levels of illuminations, and under hydrostatic pressure. Authors discuss bio-diversely algal territories ecologically – the hot springs with the thermophiles or acido-thermophiles; Antarctica, the Arctic, and permafrost zones with their cold lovers (Psychrophiles); soda lakes with the alkaliphiles, saltine areas with halophiles. In addition to general essays, Algal species discussed in detail include diatoms, Cyanidium, Galdieria, Dunaliella, and Chroococcidiopsis. This volume is a must for students of the field of biodiversity, as well as those in phycology, ecology and general biological research.

Book Description: The halophilic microorganisms form a highly diverse group of organisms. They present the biochemist/physiologist with interesting questions on the strategies used to cope with high osmotic pressures exerted by hypersaline brines. They often have a strong impact on the ecosystems in which they thrive. The first section of the book presents in-depth discussions of the taxonomy, cellular properties, metabolic diversity, pigments, ion metabolism and organic osmotic solutes, properties of halophilic proteins, genetics, and biotechnological uses of halophilic microorganisms. The second section describes the occurrence and functioning of these organisms in the Great Salt Lake, the Dead Sea, solar saltern ponds, alkaline soda lakes, and other hypersaline environments worldwide. Each chapter contains an extensive list of references. No other book provides in-depth up-to-date coverage of all subjects described. The volume is intended for researchers and students interested in microbial physiology, microbial ecology, environmental sciences, and extremophilic biotechnology.

Book Description: Model Ecosystems in Extreme Environments examines ecosystems at the most extreme habitats and their interaction with the environment, which is key to understanding the role and function of microorganisms in nature, and consequently the implications of life at local and global scales. It also highlights current topics in the field, such as biodiversity and the structure of microbial communities in extreme environments, the effects of extreme environmental conditions on microbial ecosystems, and ecological and evolutionary interactions in extreme environments, among many others. Model Ecosystems in Extreme Environments is a valuable text for an interdisciplinary audience, including faculty and students working with extremophiles and/or microbial ecology and researchers in a number of fields, including astrobiologists, biologists, evolutionary scientists, astronomers, geochemists, and oceanographers. Explores in detail how microbial ecosystems thrive in extreme environments Highlights the relevance of extremophiles as model ecosystems to the study of microbial ecology Examines how extreme ecosystems could help our search for life on other planets

Book Description: Actinobacteria are highly diverse prokaryotes that are ubiquitous in soil, freshwater and marine ecosystems. Although various studies have focused on the ecology of this phylum, data are still scant on the diversity, abundance and ecology of actinobacteria endemic to special and extreme environments, such as gut, plant, alkaline saline soil, deep sea sediments, hot springs and other habitats. Actinobacteria are well-known producers of a vast array of secondary metabolites, many of which have useful applications in medicine and agriculture. Furthermore, actinobacteria also have diverse functions in different environments apart from antibiotic production. For example, actinobacteria are reported to contribute to the break-down and recycling of organic compounds. They play a significant role in fixation of nitrogen, improvement plant growth, biodegradation, bioremediation and environmental protection. Therefore, understanding the actinobacterial diversity and distribution in such special environments is important in deciphering the ecological roles of these microorganisms and for biotechnological bioprospecting. Recent advances in cultivation, DNA sequencing technologies and -omics (metagenomics, metaproteomics etc) methods have greatly contributed to the rapid advancement of our understanding of microbial diversity, function and they interactions with environment. Furthermore, comparative genomic studies can provide overall information about actinobacterial speciation, evolution, metabolism and environment adaptation mechanisms. This research topic comprising reviews and original articles highlights the recent advances regarding the unexpectedly diverse/rare group of actinobacteria with special selective isolation methods or culture-independent methods, as well as their biological activities, ecophysiologica function and mechanisms from diverse special and extreme environments.

Book Description: Koki Horikoshi — discoverer of the alkaliphiles, microbes that thrive in alkaline environments — describes in his autobiography how the research on extremophiles started and developed. He is a pioneer in the study of these microorganisms that thrive in extreme conditions, and in his book he opens a new vista of the microbial world, pushing the field to expand from the surface of the Earth to the subsurface, to the deep sea and outer space. All major developments in extremophiles research are covered, stretching back to the historical use of microbes in mixed fermentation, indigo dyeing and the pasteurisation of sake. Events in Horikoshi’s life provide many valuable insights into the life of a budding scientist, inspired by the Renaissance culture of Florence that led him to the discovery of the alkaliphiles. Our daily lives have been greatly affected by Horikoshi’s research, such as the extensive screening he conducted for enzymes produced by alkaliphiles, now applied in many industries from biological laundry detergents to pharmaceutics. The book also reflects on numerous milestone events and people who contributed to the establishment of this field, including colleagues from all over the world. This book is a good read for all microbiologists, encouraging readers to reach out to new worlds and discoveries. It will be treasured by all those interested in a life of a real pioneer.
