Opis

With the Twenty-Third Symposium, we sustained the tradition of providing an informal, congenial atmosphere that our participants find conducive to pursuing technical discussion of program topics. The techni cal program consisted of six sessions with 38 oral presentations, a roundtable forum, two special topic discussions and a poster session con sisting of 230 posters. A special luncheon talk on "Natural Capitalism" by Karl Rabago of the Rocky Mountain Institute was particularly enlightening. More infor mation on these provocative approaches to resources and societal needs can be found at their website, www.rmi.org. While plant biotechnology and genetically modified organisms (GMOs) for enzyme production and designer biomass emerged as exciting areas throughout the Symposium, the frank exchange in the special topic sessions indicated the importance of thinking beyond the purely technical details in this important research area. The preface for each session is included in the introductions.

In Biotechnology for Fuels and Chemicals: The Twenty-Third Symposium, leading US and international researchers from academia, industry, and government present state-of-the-art research on how biotechnology is being used to produce economically competitive fuels and chemicals. The articles range from a discussion of advances in biomass production and processing, to commercialization of bio-based products. Additional topics include enzyme and microbial biocatalysts, bioprocessing research and development, the pros and cons of mixing oil and ethanol, and emerging biorefinery opportunities. The field continues to expand, and the ideas and techniques described will play important roles in developing new biological processes for producing fuels and chemicals on a large scale, and for reducing pollution and waste disposal problems, and their adverse impacts on global climate change. Cutting-edge and authoritative, Biotechnology for Fuels and Chemicals: The Twenty-Third Symposium provides an excellent overview of current research and development in the production of commodity fuels and chemicals via biological transformation.
