Описание: Provided here is an up-to-date survey of gene transfers inthe main natural habitats, with a special reference togenetically engineered microorganisms.In the first of fivesections technical approaches of gene transfer in thenatural environment are developed.
Описание: This book intends to provide information about detection and health effects due to bacteria, fungi and viruses in indoor environments. The book also intends to fill a gap regarding information about all biologic agents, since most of the books available are dedicated to only one type of microorganisms.

Описание: This book will highlight advanced techniques that were recently used for studying microorganisms in extreme environments. Recent technological leaps in the study of microorganisms in the environment now make it possible to comprehensively study microbes in the environment. Extreme environments could benefit from the application of these techniques, but many challenges such as low biomass, low activity and slow growth has prevented their wide adoption. This book will review recent application of state-of-the-art techniques in extreme environments, helping researcher and graduate students get a better knowledge of the tools available.

Описание:
The cryosphere stands for environments where water appears in a frozen form. It includes permafrost, glaciers, ice sheets, and sea ice and is currently more affected by Global Change than most other regions of the Earth. In the cryosphere, limited water availability and subzero temperatures cause extreme conditions for all kind of life which microorganisms can cope with extremely well. The cryosphere’s microbiota displays an unexpectedly large genetic potential, and taxonomic as well as functional diversity which, however, we still only begin to map. Also, microbial communities influence reaction patterns of the cryosphere towards Global Change. Altered patterns of seasonal temperature fluctuations and precipitation are expected in the Arctic and will affect the microbial turnover of soil organic matter (SOM). Activation of nutrients by thawing and increased active layer thickness as well as erosion renders nutrient stocks accessible to microbial activities. Also, glacier melt and retreat stimulate microbial life in turn influencing albedo and surface temperatures. In this context, the functional resilience of microbial communities in the cryosphere is of major interest. Particularly important is the ability of microorganisms and microbial communities to respond to changes in their surroundings by intracellular regulation and population shifts within functional niches, respectively.
Research on microbial life exposed to permanent freeze or seasonal freeze-thaw cycles has led to astonishing findings about microbial versatility, adaptation, and diversity. Microorganisms thrive in cold habitats and new sequencing techniques have produced large amounts of genomic, metagenomic, and metatranscriptomic data that allow insights into the fascinating microbial ecology and physiology at low and subzero temperatures. Moreover, some of the frozen ecosystems such as permafrost constitute major global carbon and nitrogen storages, but can also act as sources of the greenhouse gases methane and nitrous oxide. In this book we summarize state of the art knowledge on whether environmental changes are met by a flexible microbial community retaining its function, or if the altered conditions also render the community in a state of altered properties that affect the Earth’s element cycles and climate. This book brings together research on the cryosphere’s microbiota including permafrost, glaciers, and sea ice in Arctic and Antarctic regions. Different spatial scales and levels of complexity are considered, spanning from ecosystem level to pure culture studies of model microbes in the laboratory. It aims to attract a wide range of parties with interest in the effect of climate change and/or low temperatures on microbial nutrient cycling and physiology.

Описание:
Pollution has accompanied polar exploration since Captain John Davis' arrival on the Antarctic continent in 1821 and has become an unavoidable consequence of oil spills in our polar regions. Fortunately, many of the organisms indigenous to Polar ecosystems have the ability to degrade pollutants. It is this metabolic capacity that forms the basis for bioremediation as a potential treatment for the hydrocarbons that contaminate the pristine polar environments.
The only book to cover the breadth of microbial ecology and diversity in polar regions with an emphasis on bioremediation, Polar Microbiology: The Ecology, Biodiversity, and Bioremediation Potential of Microorganisms in Extremely Cold Environments examines the diversity of polar microorganisms and their ability to degrade petroleum hydrocarbon contaminants in polar terrestrial and aquatic environments. Providing a unique perspective of these microorganisms in extremely cold temperatures, the book focuses on their taxonomy, physiology, biochemistry, population structure, bioremediation potential, and potential for biotechnology applications. Leading investigators in the field provide complete coverage of the microbiology relevant to the study of biodiversity and biodegradation of pollutants in the Arctic and Antarctic, including:
Microbial extremophiles living in cold and subzero temperature environments
Genetics and physiology of cold adaptation of microorganisms
Biodegradative microbial consortia in a defined closed environment
Molecular characterization of biodegradative microbial populations
Molecular approaches to assess biodegradation of petroleum hydrocarbons
Environmental impact of hydrocarbon contamination
Microbial biodiversity across Antarctic deserts

Описание: During the mid-forties bacteria and phages were dis- covered to be suitable objects for the study of genet- ics. Genetic phenomena such as mutation and recombina- tion, which had already been known in eukaryotes for a long time, were now shown to exist in bacteria and phages as well. New phenomena as lysogeny and trans- duction were discovered, which gained great importance beyond the field of microbial genetics. Bacteria and phages are of small size, multiply rapid- ly, and have chemically defined growth requirements. Many selective procedures can be applied to screen for rarely occurring mutants or recombinants. Therefore, they offered ideal conditions to investigate genetic processes and to interpret them in molecular terms. Many new methods were developed (e. g. CsCl density gradient centrifugation) and old techniques were im- proved and modified for new purposes (e. g. chemical mutagenesis). Hypotheses, such as the semiconservative replication of DNA, mutation by transition and trans- version and operon regulation, have had an extraordi- narily stimulating effect on the research in general genetics. Thus, in the past two decades, from the ge- netics of microbes (including fungi) the field of mo- lecular genetics developed. Many text books compete in presenting the latest knowledge on this subject. But to date there are only a few laboratory manuals which introduce the student of biology to the manifold ex- perimental techniques of microbial and molecular gene- tics. This laboratory manual is an attempt to redress the balance.

Описание:
Genetic investigations and manipulations of bacteria and bacteriophage have made vital contributions to our basic understanding of living cells and to the development of molecular biology and biotechnology. This volume is a survey of the genetics of bacteria and their viruses, and it provides students with a comprehensive introduction to this rapidly changing subject. The book is written for upper level undergraduates and beginning graduate students, particularly those who have had an introductory genetics course.
The fifth edition has been extensively revised to reflect recent advances in the field. The book now has a reader-friendly look, with end-of-chapter questions, "Thinking Ahead" and "Applications" boxes to challenge students' comprehension and insights. A complete glossary of commonly used terms has been revised and expanded.
