The proteins that gather light for plant photosynthesis are embedded within cell membranes in a site called the thylakoid membrane (or the "photosynthetic membrane"). These proteins form the light harvesting antenna that feeds with energy a number of vital photosynthetic processes such as water oxidation and oxygen evolution, the pumping of protons across the thylakoid membranes coupled with the electron transport chain of the photosystems and cytochrome b6f complex, and ATP synthesis by ATP synthase utilizing the generated proton gradient. The Photosynthetic Membrane: Molecular Mechanisms and Biophysics of Light Harvesting is an introduction to the fundamental design and function of the light harvesting photosynthetic membrane, one of the most common and most important structures of life. It describes the underlying structure of the membrane, the variety and roles of the membrane proteins, the atomic structures of light harvesting complexes and their macromolecular assemblies, the molecular mechanisms and dynamics of light harvesting and primary energy transformations, and the broad range of adaptations to different light environments. The book shows, using the example of the photosynthetic membrane, how complex biological structures utilize principles of chemistry and physics in order to carry out biological functions. The Photosynthetic Membrane: Molecular Mechanisms of Light Harvesting will appeal to a wide audience of undergraduate and postgraduate students as well as researchers working in the fields of biochemistry, molecular biology, biophysics, plant science and bioengineering.

To address the environmental, socioeconomic, and geopolitical issues associated with increasing global human energy consumption, technologies for utilizing renewable carbon-free or carbon-neutral energy sources must be identified and developed. Among renewable sources, solar energy is quite promising as it alone is sufficient to meet global human demands well into the foreseeable future. However, it is diffuse and diurnal. Thus effective strategies must be developed for its capture, conversion and storage. In this context, photosynthesis provides a paradigm for large-scale deployment. Photosynthesis occurs in plants, algae, and cyanobacteria and has evolved over 3 billion years. The process of photosynthesis currently produces more than 100 billion tons of dry biomass annually, which equates to a global energy storage rate of ~100 TW. Recently, detailed structural information on the natural photosynthetic systems has been acquired at the molecular level, providing a foundation for comprehensive functional studies of the photosynthetic process. Likewise, sophisticated spectroscopic techniques have revealed important mechanistic details. Such accomplishments have made it possible for scientists and engineers to construct artificial systems for solar energy transduction that are inspired by their biological counterparts. The book contains articles written by experts and world leaders in their respective fields and summarizes the exciting breakthroughs toward understanding the structures and mechanisms of the photosynthetic apparatus as well as efforts toward developing revolutionary new energy conversion technologies. The topics/chapters will be organized in terms of the natural sequence of events occurring in the process of photosynthesis, while keeping a higher-order organization of structure and mechanism as well as the notion that biology can inspire human technologies. For example, the topic of light harvesting, will be followed by charge separation at reaction centers, followed by charge stabilization, followed by chemical reactions, followed by protection mechanisms, followed by other more specialized topics and finally ending with artificial systems and looking forward. As shown in the table of contents (TOC), the book includes and integrates topics on the structures and mechanisms of photosynthesis, and provides relevant information on applications to bioenergy and solar energy transduction.

This book covers the state-of-the-art of microalgae physiology and biochemistry (and the several –omics). It serves as a key reference work for those working with microalgae, whether in the lab, the field, or for commercial applications. It is aimed at new entrants into the field (i.e. PhD students) as well as experienced practitioners. It has been over 40 years since the publication of a book on algal physiology. Apart from reviews and chapters no other comprehensive book on this topic has been published. Research on microalgae has expanded enormously since then, as has the commercial exploitation of microalgae. This volume thoroughly deals with the most critical physiological and biochemical processes governing algal growth and production.

Harnessing the sun’s energy via photosynthesis is at the core of sustainable production of food, fuel, and materials by plants, algae, and cyanobacteria. Photosynthesis depends on photoprotection against intense sunlight, starting with the safe removal of excess excitation energy from the light-harvesting system, which can be quickly and non-destructively assessed via non-photochemical quenching of chlorophyll fluorescence (NPQ). By placing NPQ into the context of whole-organism function, this book aims to contribute towards identification of plant and algal lines with superior stress resistance and productivity. By addressing agreements and open questions concerning photoprotection’s molecular mechanisms, this book contributes towards development of artificial photosynthetic systems. A comprehensive picture –from single molecules to organisms in ecosystems, and from leading expert’s views to practical information for non-specialists on NPQ measurement and terminology – is presented.

The Encyclopedia of Plant Physiology series has turned several times to the topic of photosynthesis. In the original series, two volumes edited by A. PIRSON and published in 1960 provided a broad overview of the entire field. Although the New Series has devoted three volumes to the same topic, the overall breadth of the coverage has had to be restricted to allow for greater in-depth treatment of three major areas of modern photosynthesis research: I. Photosynthetic Elec tron Transport and Photophosphorylation (Volume 5 edited by A. TREBST and M. AvRON, and published in 1977); II. Photosynthetic Carbon Metabolism and Related Processes (Volume 6 edited by M. GIBBS and E. LATZKO, and published in 1979); and III. Photosynthetic Membranes and Light-Harvesting Systems (this volume). As we approached the organization of the current volume, we chose a set of topics for coverage that would complement the earlier volumes, as well as provide updates of areas that have seen major advances in recent years. In addition, we wanted to emphasize the following changes in the study of photo synthetic systems which have become increasingly important since 1977: the trend toward increased integration of biochemical and biophysical approaches to study photosynthetic membranes and light-harvesting systems, and a renewed appreciation of the structural parameters of membrane organization.

Biophysics represents perhaps one of the best examples of interdisciplinary research areas, where concepts and methods from disciplines such as physics, biology, b- chemistry, colloid chemistry, and physiology are integrated. It is by no means a new ?eld of study and has actually been around, initially as quantitative physiology and partly as colloid science, for over a hundred years. For a long time, biophysics has been taught and practiced as a research discipline mostly in medical schools and life sciences departments, and excellent biophysics textbooks have been published that are targeted at a biologically literate audience. With a few exceptions, it is only relatively recently that biophysics has started to be recognized as a physical science and integrated into physics departments’ curr- ula, sometimes under the new name of biological physics. In this period of cryst- lization and possible rede?nition of biophysics, there still exists some uncertainty as to what biophysics might actually represent. A particular tendency among phy- cists is to associate biophysics research with the development of powerful new te- niques that should eventually be used not by physicists to study physical processes in living matter, but by biologists in their biological investigations. There is value in that judgment, and excellent books have been published that introduce the int- ested reader to the use of physical principles for the development of new methods of investigation in life sciences.

This landmark collective work introduces the physical, chemical, and biological principles underlying photosynthesis: light absorption, excitation energy transfer, and charge separation. It begins with an introduction to properties of various pigments, and the pigment proteins in plant, algae, and bacterial systems. It addresses the underlying physics of light harvesting and key spectroscopic methods, including data analysis. It discusses assembly of the natural system, its energy transfer properties, and regulatory mechanisms. It also addresses light-harvesting in artificial systems and the impact of photosynthesis on our environment. The chapter authors are amongst the field�s world recognized experts. Chapters are divided into five main parts, the first focused on pigments, their properties and biosynthesis, and the second section looking at photosynthetic proteins, including light harvesting in higher plants, algae, cyanobacteria, and green bacteria. The third part turns to energy transfer and electron transport, discussing modeling approaches, quantum aspects, photoinduced electron transfer, and redox potential modulation, followed by a section on experimental spectroscopy in light harvesting research. The concluding final section includes chapters on artificial photosynthesis, with topics such as use of cyanobacteria and algae for sustainable energy production.

Life on earth depends on the photosynthetic use of solar energy by plants, and efforts to develop alternative sources of energy include a major thrust toward the use of photosynthesis to yield fuels. The study of photosynthesis is an especially convincing way of bringing together the disciplines of physics, chemistry, and biology and can be a valuable element in the teaching of biophysics and biochemistry. This book provides the only detailed modern treatment of the subject in a concise form. Part I outlines the historical development of the subject, emphasizing the chemical nature of photosynthesis and the roles of chlorophylls and other pigments. Part II reviews our present knowledge of the structure and components of photosynthetic tissues in relation to their function. Part III deals with the photo-chemistry of photosynthesis and with the patterns of chemical events, principally electron and proton transfer, that follow the photo-chemistry. Part IV treats the relationships of electron and proton transport to ATP formation, and the metabolic patterns of carbon assimilation. An epilogue exposes major areas of confusion and ignorance and indicates potentially fruitful directions of research, including the development of photosynthetic systems for solar energy conversion. Throughout the book, there are frequent digressions into those aspects of optics and molecular physics relevant to the subject matter. Suitable for upper undergraduate and graduate course use, this book is also sufficiently detailed to give professional scientists a perspective of the subject at the level of contemporary research.

Biophysics, being an interdisciplinary topic, is of great importance in modern biology. This book addresses the needs of biologists, biochemists, and medical biophysicists for an introduction to the subject. The text is based on a one-semester course offered to graduate students of life sciences, and covers a wide range of topics from quantum mechanics to pre-biotic evolution. To understand the topics, only basic school level mathematics is required. The first chapter introduces and refreshes the reader's knowledge of physics and chemistry. The next chapters cover various physico-chemical techniques used to study biomolecular structures, followed by treatments of spectroscopy, microscopy, diffraction, and computational techniques. X-ray crystallography and NMR are dealt with in greater detail. The latter half of the book covers results obtained from applications of the above techniques. Some of the other topics dealt with are energy pathways, biomechanics, and neuro-biophysics.

Aquatic Photosynthesis is a comprehensive guide to understanding the evolution and ecology of photosynthesis in aquatic environments. This second edition, thoroughly revised to bring it up to date, describes how one of the most fundamental metabolic processes evolved and transformed the surface chemistry of the Earth. The book focuses on recent biochemical and biophysical advances and the molecular biological techniques that have made them possible. In ten chapters that are self-contained but that build upon information presented earlier, the book starts with a reductionist, biophysical description of the photosynthetic reactions. It then moves through biochemical and molecular biological patterns in aquatic photoautotrophs, physiological and ecological principles, and global biogeochemical cycles. The book considers applications to ecology, and refers to historical developments. It can be used as a primary text in a lecture course, or as a supplemental text in a survey course such as biological oceanography, limnology, or biogeochemistry.

Photosynthesis is a process on which virtually all life on Earth depends. To answer the basic questions at all levels of complexity, from molecules to ecosystems, and to establish correlations and interactions between these levels, photosynthesis research - perhaps more than any other discipline in biology - requires a multidisciplinary approach. Congresses probably provide the only forums where progress throughout the whole field can be overviewed. The Congress proceedings give faithful pictures of recent advances in photosynthesis research and outline trends and perspectives in all areas, ranging from molecular events to aspects of photosynthesis on the global scale. The Proceedings Book, a set of 4 (or 5) volumes, is traditionally highly recognized and intensely quoted in the literature, and is found on the shelves of most senior scientists in the field and in all major libraries.

Progress in photosynthesis research is strongly dependent on instrumentation. It is therefore not surpr- ing that the impressive advances that have been made in recent decades are paralleled by equally impressive advances in sensitivity and sophistication of physical equipment and methods. This trend started already shortly after the war, in work by pioneers like Lou Duysens, the late Stacy French, Britton Chance, Horst Witt, George Feher and others, but it really gained momentum in the seventies and especially the eighties when pulsed lasers, pulsed EPR spectrometers and solid-state electronics acquired a more and more prominent role on the scene of scientific research. This book is different from most others because it focuses on the techniques rather than on the scientific questions involved. Its purpose is three-fold, and this purpose is reflected in each chapter: (i) to give the reader sufficient insight in the basic principles of a method to understand its applications (ii) to give information on the practical aspects of the method and (iii) to discuss some of the results obtained in photosynthesis research in order to provide insight in its potentalities. We hope that in this way the reader will obtain sufficient information for a critical assessment of the relevant literature, and, perhaps more important, will gain inspiration to tackle problems in his own field of research. The book is not intended to give a comprehensive review of photosynthesis, but nevertheless offers various views on the exciting developments that are going on.

In recent years it has become evident that transport processes across membranes play a crucial role in many metabolic systems. The activities of these transport processes often determine the physiology of the organisms. This book presents a state of the art review on the analysis of a wide variety of transport systems from bacteria and eukaryotic cells. A selection has been made of those systems that have been studied at the molecular level with special emphasis paid to the energetic and other biophysical properties. The different classes of transport systems are presented in the following: primary transport, secondary transport, phosphotransferase systems, channels and porines and macromolecular transport. Within each class of transporters several systems are presented by the leading experts in the field, which has resulted in a very broad overview of transport processes in biological cells. In this way the differences in the mechanisms used for translocation become evident while on the other hand features common to the different transport systems are revealed.
