Opis

153 posters. While plant biotechnology for enzyme production and designer biomass merged as "hot topics" throughout the Symposium, the preface for each session is included in the introductions. Special topic discussions were led on "Brazilian Bioethanol Progress" by Gisella Zanin, State University of Maringa, Brazil, and on "Nontradi tional Bioprocessing" by Gene Petersen, National Renewable Energy Labo ratory, Golden, CO. A tour of the Colorado Bioprocessing Center, a "state of the art" con tract research facility at Colorado State University highlighted the process development and scale-up activities ongoing with several industrial clients. The 1999 Charles D. Scott Award for Distinguished Contributions in the field of Biotechnology for Fuels and Chemicals was presented to Dr. Charles E. Wyman, Dartmouth College professor, Thayer School of Engineering, Hanover, New Hampshire. This award is named in honor of Dr. Charles D. Scott, the founder of this Symposium and its chair for the first ten years."
