Algal Culturing Techniques is a comprehensive reference on all aspects of the isolation and cultivation of marine and freshwater algae, including seaweeds. It is divided into seven parts that cover history, media preparation, isolation and purification techniques, mass culturing techniques, cell counting and growth measurement techniques, and reviews on topics and applications of algal culture techniques for environmental investigations.

Algal Culturing Techniques was developed to serve as both a new textbook and key reference for phycologists and others studying aquatic systems, aquaculture and environmental sciences. Students of algal ecology, marine botany, marine phycology, and microbial ecology will enjoy the hands-on methodology for culturing a variety of algae from fresh and marine waters. Researchers in industry, such as aquaculture, pharmaceutical, foodstuffs, and biotechnology companies will find an authoritative and comprehensive reference.

Sponsored by the Phycological Society of America Features color photographs and illustrations throughout Describes culturing methods ranging from the test tube to outdoor ponds and coastal seaweed farms Details isolation techniques ranging from traditional micropipette to automated flow cytometeric methods Includes purification, growth, maintenance, and cryopreservation techniques Highlights methods for estimating algal populations, growth rates, isolating and measuring algal pigments, and detecting and culturing algal viruses Features a comprehensive appendix of nearly 50 algal culture medium recipes Includes a glossary of phycological terms

Originally published in 1986, this book presents an in-depth treatment of the biology of the chrysophytes. The papers collected here are a result of the First International Chrysophyte Symposium held at the University of North Dakota in 1953. The 'golden algae', a group of predominantly fresh water microorganisms, have distinctive features that present much information about their taxonomic classification, their place in evolution and their role in the environment. The ecological significance of the chrysophytes is evident from their abundance in acid bogs and lakes, a condition that has created a new group of investigators concerned with these unique algae and the changing environment. These are just some of the aspects of chrysophyte biology that are discussed here. This book provides a strong foundation towards understanding today's living forms of chrysophyte algae and sheds light on the probable aquatic ecosystems of the past.

Protists represent an immensely diverse group of organisms comprised of algae, fungi and protozoa. The nature of protistan cell surface is as diverse as the terminology that has evolved to describe the various surface components. This terminology is defined and discussed in the opening of this book. The remaining contributions provide an up-to-date synopsis of structure, development and function of protistan cell surfaces, including their role in taxonomy and systematics.
