The Fermentation and Biotechnology Division of the American Chemical Society annually organizes symposia on topics vital to the applied biosciences. In September, 1969, a symposium was held on "Properties and Products of Algae". Papers presented at this symposium covered numerous aspects of algal culture with emphasis on the special properties and products produced by algae of economic interest. The art of handling algae is rapidly becoming a science. The papers presented herein are part of man's attempt to understand the contribution of the algae to man's world. v Contributors to this Volume: H. H.
