This book is a compendium of knowledge on the useful properties of algae in the context of application as a useful component of innovative natural products. It presents all aspects of industrial applications of macroalgae biomass derived from the natural environment. Despite many interesting characteristics, algae are still regarded as undervalued raw material, therefore, present in the following chapters are not only environmental benefits arising from the development of excessive algal biomass, but also the distribution and biology of algae in natural conditions in reservoirs, methods of obtaining extracts from biomass of algae for industrial purposes. Furthermore, it also includes topics such as the use of biomass and algae extracts for the industrial purposes, in animal breeding and for agricultural purposes, as well as the economic aspects of algae biomass harvesting for industrial purposes. The book is intended for a wide audience interested in new methods of obtaining the biomass from the natural environment for industrial purposes and the manufacture of products based on bioactive substances obtained from the environment.

High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity.  As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.

Microalgae and cyanobacteria are a very diverse group of photosynthetic microorganisms with many applications. Some of them are related to the accumulation of molecules involved in specific metabolic pathways such as pigments, fatty acids, polyunsaturated fatty acids, carbohydrates, amino acids, etc. Also, there are uses of the biomass related to the exploitation of physiological necessities such as the absorption of essential nutrients (the removal of nitrogen and phosphorus from wastewater, the capture of CO2 from the fixation of nitrogen, etc.). Nevertheless, the evaluation in financial and life-cycle aspects is necessary to ensure the industrial application of the processes. The objective of the book is to analyze innovative applications of microalgae and cyanobacteria to develop environmental-friendly processes for removal of pollutants, wastewater treatment, production of high-value products or bioenergy, and finally evaluate the feasibility of the processes both ineconomic and sustainability aspects.

Tropical seaweeds represent a major source of diversity and potential for cultivation. Cultivation of seaweeds has been coined “phyconomy” (derived from phycology and agronomy). One of the world’s most important groups of tropical seaweeds is the eucheumatoids (comprising members of the genera Kappaphycus and Eucheuma). Whilst the biomass from these seaweeds is mostly used to produce colloids (i.e., various carrageenans) trends are changing and new, value-added applications are emerging including bioactives for agriculture, pharmaceutical applications, as well as bioplastics and possibly energy when processed as part of a MUZE (i.e., multi-stream, zero effluent), or biorefinery approach. Phyconomic activities around the production of seaweed biomass provides socio-economic benefits for many hundreds of thousands of global, coastal dwellers around a circum-tropical belt. However, times are changing and the once, repetitive manual aspects of attaching seaweed fragments to ropes and nets is beginning to be mechanized. Whilst it has taken agronomy several thousands of years to develop on land, its phyconomic counterpart is, at best, 50 years old in relation to developments in cultivation of eucheumatoids. Activities around cultivation of these tropical seaweeds can contribute to achieving the UN Sustainable Development Goals.This book contains contributions from many of the world’s authorities on tropical seaweed farming with a focus on the eucheumatoids. There are many lessons learned and best-practice examples which will be of interest to students of phyconomy (phycology), marine science, industrial users of cultivated biomass, as well as practitioners in charge of coastal zone management and ensuring responsible and sustainable socio-economic benefits are derived from marine resources for coastal dwellers.

Phyconomy encompasses the science and arts of both wild harvesting and cultivation of seaweeds. Some of these practices are as ancient as the very earliest uses of selected seaweeds, going back millennia. Other phyconomic practices are some of the most recent developments applied to the selection, breeding and multiplication of strains of resilient and productive cultivated species, specifically selected for the ever-changing marine environment in which they need to succeed. Phyconometrics involves measurement of stocks, impacts of harvesting as well as production, in the sea and on land; providing data on volumes and values of commercial species, some at very large industrial scales.In so much as tropical phyconomy has been covered (with particular attention to eucheumatoids), by the editorial team in other volumes of the DAPH book series, we realised there was also a large world of temperate activities covering micro and macroalgal species which had not previously been collated and presented to the applied phycological, phyconomic community. That has now been rectified! The co-editorial team of Anicia Q. Hurtado, Iain C. Neish and Alan T. Critchley were grateful to receive the additional assistance of Leonel Pereira and the project Temperate Phyconomy began. It soon became evident there was such a wealth of novel information that could be provided from temperate waters around the phyconomic world and indeed so much so that the title expanded to: Advances in Temperate Phyconomy: Algal Harvest and Cultivation in Globally Distributed Temperate Waters.Part I looks at specific topics of phyconomy including wild vs cultivated seaweed species. It dispels some of the myths around get the get-rich-quick seaweed production schemes; it presents some stark facts based in reality on applied phycology and what it takes to obtain quality seaweed biomass for many value-added applications. New developments in phyconomic practices, harvest, cultivation methods and materials, including strain selection and seed bank maintenance are detailed with a specific focus on temperate regions of the world.Part II will follow with another set of exciting developments on temperate phyconomy from around the world of temperate seaweeds of economic value.The book is aimed at all students, researchers, operators and practitioners in the sphere of applied phycology and phyconomy, i.e., both the macro and microalgal worlds - where there is much in common – if you look with eyes wide open. The book is a great way to read the specifics and also be able to browse relevant areas, presented by global leading teams, in their various phyconomic fields; it is full of information which might not pop up in an online search. In essence anyone working with algae commercially would gain benefits from reading and inwardly digesting the book’s contents from start to finish.

Advances in Temperate Phyconomy: Algal Harvest and Cultivation in Globally Distributed Temperate Waters Part I , was published Jan. 2026. Part II provides a compilation of 23 additional chapters, by leaders in multiple, phyconomic aspects of temperate and cold-water production of algal biomass. These chapters encompass a wide spectrum of issues related to the management of biodiversity and biosecurity, wild harvesting and cultivation, cropping efficiencies and maintenance, socio-economics and value-addition to temperate algae. Global lessons can be learned from the intensive and extensive production and utilisation of selected algal biomass, produced by a variety of open water and on land systems. Readers benefit from the shared experiences and detailed comparisons between phyconomic advances in selected examples of micro and macroalgal genomics, bio-banking and intensive grow-out scenarios and sustainable valorisation of the biomass. The keys to the future, are lessons from the past!Indubitably all 52 chapters in Advances in Temperate Phyconomy Parts I and II are inseparable companions. Individually and collectively, they have something for everyone and will serve as a rich reference and compendium for a number of years to come. The books will be of benefit to those interested in applied phycology: students, academics, practitioners, and regulators alike. Pick up these tomes and read often; indulge you inner phyconomist!We sincerely hope you enjoy the diversity of information held within the contents and benefit greatly from reading both books and learning as much as we have from being the co-editors of this exciting project, with the further distinct privilege of making this information available globally.

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.

This book collates the latest information on Kappaphycus and Eucheuma seaweeds. The edited volume provides an important companion to anyone studying or working with what is the world’s largest cultivated marine plant biomass. The contributing authors have excelled in providing information on production and present and future uses of these carrageenan-bearing seaweeds. Important elements of taxonomy, distribution and methods of cultivation and processing are presented to the reader in an accessible and easily understood format. The book provides a number of valuable opinions on value addition and MUZE technologies which highlight value-chains associated with these important red algae.

This book presents the dynamic role of algae in a sustainable environment. Two major aspects, namely bioenergy and bioremediation, have been elaborated in various chapter contributed by scientists and teachers from different geographical areas throughout the world. Algal biofuels is an emerging area of equal interest to researchers, industries, and policy makers working or focusing on alternative (i.e. renewable) fuels. Algae have been an area of interest due to their wide range of applications. Over the last 5 decades, eukaryotic algae have been used in the aquaculture industry as feed for invertebrates, providing a rich source of antioxidants, dietary fiber, minerals and protein. More recently, there has been a focus on the use of algal biomass in the development of alternative fuels. The extraction of oil from algae has been widely explored as a much more viable feedstock than plant-based oils in large-scale fuel production. using algae as feedstock has the advantages that it doesn’t require arable land and that wastewater can be used as a source of nutrients in their culture. The multifunctional approach of algae includes pollution remediation, carbon sequestration, biofuels production, and delivery of value-added products. However, there are still some obstacles that need to be overcome to make their use as potential feedstock for biofuels techno-economically feasible. In order to maintain the sustainability aspect of algal biofuels, various aspects have to be studied and critically analyzed to assess the long-term sustainability of algal derived biofuels.This book discusses the role of algae as a promising future feedstock for biofuels. They are known to sequester carbon in much larger amounts than plants and as such the book also describes their phycoremediation potential for conventional as well as emerging contaminants. It describes the role of anaerobic digestion in algal biorefineries; bioreactions and process parameters; biogas recovery and reuse. The role of algal biofilm based technology in wastewater treatment and transforming waste into bio-products is discussed, and remediation of sewage water through algae is assessed.  The book also describes the production of biohydrogen, bio-oil, biodiesel; and the major bottlenecks in their usage. The emerging characterization techniques of these biofuels (bio-oil and biodiesel) are described, as are the decolorizing potential of algae and the genetic engineering techniques that could enhance the production of lipids in algae. Other aspects of the book include the role of remote sensing technology in the monitoring of algae and a life cycle assessment of algal biofuels.

India has 7,500 km of coastline with diverse habitats and rich biota. Coastal ecosystems, unfortunately, are experiencing wide range of pressures due to siltation, eutrophication, coastal development, aquaculture and climate change. Those species that adapt to these pressures will expand their living boundaries while others may fade away. Accordingly, the study of coastal biodiversity is of great concern globally and constitutes an important element of global change research. Gujarat has 1,600 km of coastline, reportedly with rich diversity of seaweeds. Previously published accounts on seaweed biodiversity were mainly in the form of checklists, the earliest among these being the checklist of Krishnamurthy and Joshi prepared in the early 1970s. The more recent checklists are based almost entirely on secondary information. The present book entitled Seaweeds of India – The Diversity and Distribution of Seaweeds of Gujarat Coast is a timely publication based wholly on primary data. Data were collected through extensive and systematic ? eld studies conducted by the authors during different seasons over a three year period. The authors collected nearly 200 species of seaweeds belonging to 100 genera of Chlorophyta, Phaeophyta and Rhodophyta. Twenty-four of the species are new to Gujarat coast and three are new to Indian waters. The book contains high-quality images of the different species in their existing habitats. Brief taxonomical descriptions, together with information on ecology, distribution, seasonality and abundance, are covered for each of the species.

Measurements of variable chlorophyll fluorescence have revolutionised global research of photosynthetic bacteria, algae and plants and in turn assessment of the status of aquatic ecosystems, a success that has partly been facilitated by the widespread commercialisation of a suite of chlorophyll fluorometers designed for almost every application in lakes, rivers and oceans. Numerous publications have been produced as researchers and assessors have simultaneously sought to optimise protocols and practices for key organisms or water bodies; however, such parallel efforts have led to difficulties in reconciling processes and patterns across the aquatic sciences. This book follows on from the first international conference on “chlorophyll fluorescence in the aquatic sciences” (AQUAFLUO 2007): to bridge the gaps between the concept, measurement and application of chlorophyll fluorescence through the synthesis and integration of current knowledge from leading researchers and assessors as well as instrument manufacturers.
