A significant component of many different ecosystems, cyanobacteria occupy almost every niche of the earth, including fresh and salt waters, rice fields, hot springs, arid deserts, and polar regions. Cyanobacteria, along with algae, produce nearly half the global oxygen, making assessment of their ecophysiologies important for understanding climate impacts and potential remediation. Stress Biology of Cyanobacteria: Molecular Mechanisms to Cellular Responses is a compilation of holistic responses of cyanobacteria, ranging from ecological and physiological to the modern aspects of their molecular biology, genomics, and biochemistry. Covering almost every aspect of cyanobacterial stress biology, this book is divided into two parts: Bioenergetics and Molecular Mechanisms of Stress Tolerance and Cellular Responses and Ecophysiology. The first few chapters focus on the molecular bioenergetics of photosynthesis and respiration in cyanobacteria, and provide a clear perspective on different stress tolerance mechanisms. Part I also covers the effect of specific stresses—including heavy metal, high and low temperature, salt, osmotic, and UV-B stress—on a wide range of vital physiological, biochemical, and molecular processes of cyanobacteria. Part II describes mechanisms of symbiosis, stress-induced bioproducts, and the role of environmental factors on nitrogen fixation, which along with photosynthesis is a major contributor to the current geochemical status of the planet. The text also covers mutation and cyanobacterial adaptation, and the most widely studied cyanotoxin, microcystin, which has effects on both human and animal health. With contributions from experts around the world, representing the global importance of cyanobacteria, this book provides a broad compilation of research that deals with cyanobacterial stress responses in both controlled laboratory conditions as well as in their natural environment.

Cyanobacteria constitute the most widely distributed group of photosynthetic prokaryotes found in almost all realms of the earth and play an important role in Earth’s nitrogen and carbon cycle. The gradual transformation from reducing atmosphere to oxidizing atmosphere was a turning point in the evolutionary history of the earth and made conditions for present life forms possible. Cyanobacteria: From Basic Science to Applications is the first reference volume that comprehensively discusses all aspects of cyanobacteria, including the diverse mechanisms of cyanobacteria for the advancement of cyanobacterial abilities, towards higher biofuel productivity, enhanced tolerance to environmental stress and bioactive compounds and potential for biofertilizers. Describes cyanobacterial diversity, stress biology, and biotechnological aspects of cyanobacteria Explores the global importance of cyanobacteria Provides a broad compilation of research that deals with cyanobacterial stress responses in both controlled laboratory conditions as well as in their natural environment

This technical book explores current and future applications ofsolar power as an unlimited source of energy that earth receivesevery day. Photosynthetic organisms have learned to utilizethis abundant source of energy by converting it into high-energybiochemical compounds. Inspired by the efficient conversionof solar energy into an electron flow, attempts have been made toconstruct artificial photosynthetic systems capable of establishinga charge separation state for generating electricity or drivingchemical reactions. Another important aspect ofphotosynthesis is the CO2 fixation and the production of highenergy compounds. Photosynthesis can produce biomass usingsolar energy while reducing the CO2 level in air. Biomass canbe converted into biofuels such as biodiesel and bioethanol. Undercertain conditions, photosynthetic organisms can also producehydrogen gas which is one of the cleanest sources of energy.

Reductionism to cellular and molecular mechanisms is one of the cornerstones of modern toxicology, forming the basis for a better understanding of individual toxic effects, and providing an important tool for human risk assessment. Mechanistic Toxicology is a timely textbook that provides an introduction to this important, but often neglected, area within the toxicological sciences. This book gives new insights into the processes and mechanisms underlying the toxicity of chemicals and explains how foreign compounds (drugs, environmental pollutants, industrial chemicals) exert their potentially damaging effects on cells and tissues. Features include: *an extensive number of illustrations, tables and photographs *summaries of the main learning points *question and answer reviews at the end of each chapter Mechanistic Toxicology incorporates recent advances in molecular biology and develops concepts for the reader in a logical way. It also illustrates, using many examples and complementary background information, how a better understanding of these mechanistic pathways helps in estimating potential risk to human health. Ideal for use in undergraduate and graduate classes of pharma-toxicology and environmental toxicology, Mechanistic Toxicology is also a valuable reference for any other readers interested in this subject.

Cell and Molecular Responses to Stress is a new multi-volume book series from Elsevier Science that focuses on how organisms respond at a molecular level to environmental stresses imposed upon them. All organisms deal with variations in multiple environmental factors including temperature, oxygen, salinity, and water availability. Many show amazing tolerances to extreme stress with remarkable biochemical adaptations that allow life to persist under very difficult circumstances. This series explores the molecular mechanisms by which cells and organisms respond to stress, focusing on the variations in metabolic response that allow some cells and organisms to deal with extreme stress, others to endure stress within strict limits, and others to have a very low tolerance for changes in environmental parameters. Articles from within the series highlight the elastic limits of molecular responses in Nature, with examples drawn from animal, plant and bacteria systems. Volume 1, begins by considering some of the roles of environmental stress in determining the geographic distribution of animals and in promoting species divergence and then explores gene expression and metabolic responses to environmental stress with examples of adaptation to high and low temperature, osmotic, anoxia/ischemia, desiccation, high pressure and heavy metal stresses.
