Industrial seaweed use started in Brittany in the XVII century. Today, 700 species have been identified along 1000 km of shoreline, producing 10 million tons of biomass. In the Fourteenth International Seaweed Sumposium the latest developments in the area are discussed. The blending of molecular biology with traditional taxonomy is improving our understanding of phylogeny and species relationships among many of the important algae. A new generation of biologically-based management models is gradually incorporating field testing, concepts from ecological theory and principles from population biology. Prediction is being improved, and an appropriate balance is being struck between commercial exploitation and the preservation of wild seaweed resources. Cell and tissue culture of seaweeds is entering the mass-production phase. Field farming is now entering the large-scale production area. New, biologically active compounds are being described, obtained from algae, and new tools for the characterisation of phytocolloids are described. Microalgal blooms and toxins are also experiencing a flourish of new results.

This volume provides a selection of the most significant papers presented at the 15th International Seaweed Symposium in Valdivia, Chile, in January 1995. Plenary lectures featured seaweed research and utilization in Chile by Bernabé Santelices, ethnobotany of seaweeds by Isabella Abbott, host-virus interactions in marine brown algae by Dieter Müller, DNA analysis methods for recognizing species invasion by Annette Coleman, and recent developments in manufacturing and marketing carrageenan by Harris Bixler. Other highlights include sections on integrated aquaculture using seaweeds and marine invertebrates or fishes and on diseases in seaweeds. The remaining papers cover recent advances in floristics and systematics, population studies, pollution, cultivation, economics, physiology, biochemistry, cell biology, and chemistry and chemical composition of seaweeds, particularly species of Gracilariales, Gigartinales, Gelidiales, Laminariales and Fucales.

The current era of incredible innovations has made science and technology one of the most powerful tools to meet the goals of incremental prosperity for humans and sustainable development. The development of the biotech industry in any given country is shaped by the characteristics of the technology—particularly its close relation to scientific knowledge—and by country-specific factors—the level and nature of the scientific knowledge base, the institutional set-up, and the role assumed by the government—which influence the country's ability to exploit new opportunities and appropriate the respective results. This book presents an integrated approach for sustained innovation in various areas of biotechnology. Focusing mainly on the industrial, socio-economic and legal implications of biotechnological advances, it examines in detail not only the implications of IPR in omics-based research but also the ethical and intellectual standards and how these can be developed for sustained innovation. Integrating science and business, it offers a peek behind the scenes of the biotech industry and provides a comprehensive analysis of the foundations of the present day industry for students and professionals alike. The book is divided into three parts: Food and Agricultural BiotechnologyIndustrial BiotechnologyPharmaceutical Biotechnology

This unique compendium provides an insight into the role of emerging marine biorefineries based on macroalgae (seaweeds) in the development of a sustainable use of ocean resources for economic growth-blue economy.The useful reference text shows a complete picture on the motivation to develop seaweed technologies, and how the combination of biology, cultivation technologies and downstream processing with economics can address the social challenges through the blue growth.

Seaweeds, also known as macroalgae, are among the most important primary producers and act as ecological engineers on rocky coasts of the world’s oceans. In addition to their extreme ecological importance they are also of high economic relevance. Complementing available textbooks with its more research-oriented approach, this volume contains 22 chapters by renowned experts, grouped in five parts. In Part I fundamental processes and acclimation strategies of seaweeds towards the abiotic environment are covered. Part II focuses on the multitude of biotic interactions in seaweed communities, and in Part III the reader is introduced to the structure and function of the main seaweed systems of the world. The chapters of Part IV highlight and discuss the effects of global and local environmental changes on seaweeds and their communities. In the final Part V a comprehensive overview of developments in seaweed aquaculture, industrial applications and the overall economic importance of seaweeds is provided. Summarizing the advances in seaweed biology achieved within the last few decades, this book also identifies gaps in the present knowledge and needs for future research.
