The Ecology Of Cyanobacteria

Cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions. Molecular biology has in recent years provided major advances in our understanding of cyanobacterial ecology. Perhaps for more than any other group of organisms, it is possible to see how the ecology, physiology, biochemistry, ultrastructure and molecular biology interact. This all helps to deal with practical problems such as the control of nuisance blooms and the use of cyanobacterial inocula to manage semi-desert soils. Large-scale culture of several organisms, especially "Spirulina" (Arthrospira), for health food and specialist products is increasingly being expanded for a much wider range of uses. In view of their probable contribution to past oil deposits, much attention is currently focused on their potential as a source of biofuel.

This book complements the highly successful Ecology of Cyanobacteria and integrates the discoveries of the past twelve years with the older literature.

Cyanobacteria make a major contribution to world photosynthesis and nitrogen fixation, but are also notorious for causing nuisances such as dense and often toxic `blooms' in lakes and the ocean. The Ecology of Cyanobacteria: Their Diversity in Time and Space is the first book to focus solely on ecological aspects of these organisms. Its twenty-two chapters are written by some thirty authors, who are leading experts in their particular subject. The book begins with an overview of the cyanobacteria - or blue-green algae, for those who are not specialists - then looks at their diversity in the geological record and goes on to describe their ecology in present environments where they play important roles. Why is one of the key groups of organisms in the Precambrian still one of the most important groups of phototrophs today? The importance of ecological information for rational management and exploitation of these organisms for commercial and other practical purposes is also assessed. Accounts are provided of nuisances as well as the ecology of the commercially successful Spirulina and the role of cyanobacteria in ecosystem recovery from oil pollution. Many chapters include aspects of physiology, biochemistry, geochemistry and molecular biology where these help general understanding of the subject. In addition there are three chapters dealing specifically with molecular ecology. Thirty-two pages of colour photos incorporate about seventy views and light micrographs. These features make the book valuable to a wide readership, including biologists, microbiologists, geologists, water managers and environmental consultants. The book complements the highly successful The Molecular Biology of Cyanobacteria already published by Kluwer.

Written by leading experts in the field, Cyanobacteria: An Economic Perspective is a comprehensive edited volume covering all areas of an important field and its application to energy, medicine and agriculture. Issues related to environment, food and energy have presented serious challenge to the stability of nation-states. Increasing global population, dwindling agriculture and industrial production, and inequitable distribution of resources and technologies have further aggravated the problem. The burden placed by increasing population on environment and especially on agricultural productivity is phenomenal. To provide food and fuel to such a massive population, it becomes imperative to find new ways and means to increase the production giving due consideration to biosphere’s ability to regenerate resources and provide ecological services. Cyanobacteria are environment friendly resource for commercial production of active biochemicals, drugs and future energy (biodiesel, bioethanol and hydrogen). Topics on isolation, identification and classification of cyanobacteria are discussed, as well as further sections on: summarizing a range of useful products synthesized by cyanobacteria, ecological services provided by cyanobacteria including their harmful effect in water bodies and associated flora and fauna. Chapter on tools, techniques, and patents also focus on the economic importance of the group. This book also provides an insight for future perspectives in each particular field and an extensive bibliography. This book will be a highly useful resource for students, researchers and professionals in academics in the life sciences including microbiology and biotechnology.

This outstanding volume provides an up-to-date overview of the advances in our knowledge of harmful cyanobacteria. An essential reference for all scientists and environmental professionals interested in cyanobacterial ecology and water management.

With the ever-increasing incidence of harmful cyanobacterial algal blooms, this monograph has added urgency and will be essential reading for all sorts of researchers, from neuroscientists to cancer research specialists. The volume contains the proceedings of the 2005 International Symposium on Cyanobacterial Harmful Algal Blooms, and has been edited by H. Kenneth Hudnell, of the US Environmental Protection Agency. It contains much of the most recent research into the subject.

The Pharmacological Potential of Cyanobacteria explores the bioactive compounds isolated from cyanobacteria and their relationship to human health and biotechnological applications. The book presents an overview of the chemistry and ecology of cyanobacteria, focusing on culture needs and techniques of biomass production. It is organized according to the different biological activities and biotechnological applications of compounds discovered in recent years. Besides biological activity, the mechanism of action of compounds is explained, along with molecular structure. Finally, compounds already used in therapeutics and biotechnology, as well as those in phases of approval or clinical trials are explored. Each chapter is written by a different research group with expertise in the field and publications in peer reviewed journals. Researchers and students in pharmaceutical academic research, pharmaceutical industrial sector personnel, health professionals, and nutritionists will find this book to be very useful. Covers all the bioactive compounds of cyanobacteria discovered thus far Includes chapters by experts in the field, covering the chemistry and mechanisms of action of cyanobacteria-bioactive compounds Provides a general overview of organisms, from biomass production to compound isolation and evaluation of bioactivities in different cell and cell-free systems
